DNA replication is the process by which DNA makes a copy of itself during cell division. The correct order of the steps in DNA replication is as follows:
1. Replication begins with a specific nucleotide sequence called the replication origin.
2. A group of enzymes, called the helicases, bind to the DNA at each replication origin.
3. The helicase cleave and unravel a section of the original double helix, creating Y-shaped areas (replication forks) at the end of the unwound areas, which form a replication bubble.
4. New DNA strands are produced when an enzyme called DNA polymerase inserts into the replication bubble.
5. A primase enzyme synthesizes an RNA primer that serves as the starting point of new nucleotide attachment by DNA polymerase.
6. DNA polymerase can only synthesize the new nucleotide chain in the 5' to 3' direction.
7. As a result, one strand (the leading strand) is replicated continuously in the 5' to 3' direction in the same direction that the replication fork is moving.
8. The other strand, known as the lagging strand, is replicated in short segments, still in the 5' to 3' direction, but away from the replication fork.
9. Three fragments, called Okazaki fragments, are spliced together by DNA ligase.
10. When replication is complete, DNA polymerase dismantles the RNA primer and proofreads the nitrogen base pairing of the two new DNA molecules.
11. Replication ends with each new molecule of DNA containing one parent strand and one new strand.
In summary, DNA replication is a complex process that involves a series of steps that need to occur in a specific order for successful DNA replication. Understanding the order of these steps is crucial to understanding the DNA replication process.

B. organisms collide at high speeds during

C. bedrock is liquidated due to shifting tectonic
plates
D. volcanic ash is liquidated under extreme pressure
Answers
Answer:
A
Explanation:
a - What happens when organisms don't decompose? If there were no decomposers, wastes and the remains of dead organisms would pile up and the nutrients within the waste and dead organisms would not be released back into the ecosystem. Producers would not have enough nutrients.
b - What happens when a catastrophic mass extinction occurs? A mass extinction event is when species vanish much faster than they are replaced. This is usually defined as about 75% of the world's species being lost in a 'short' amount of geological time - less than 2.8 million years
c - What does the shifting of tectonic plates cause? At the “seams” where tectonic plates come in contact, the crustal rocks may grind violently against each other, causing earthquakes and volcano eruptions. The relatively fast movement of the tectonic plates under California explains the frequent earthquakes that occur there.
d - Volcanic ash doesn't actually do that.
Now, how do fossil fuels form? After millions of years underground, the compounds that make up plankton and plants turn into fossil fuels. Fossil fuels are formed when the organic matter that has been buried deep within the earth is subject to heat and pressure over millions of years. In both cases, heat and pressure are critical to the formation of fossil fuels.

You are working in a bacterial genetics laboratory. You are studying the biosynthetic pathway for the amino acid arginine in e. Coli and have two mutant strains: arge, and argg that were generated by transposon mutagenesis. You need to perform an experiment with these two arginine biosynthesis mutants, and so you first streak them from your stock culture onto la so that they have access to arginine. Once the strains have grown on the la plate, you streak individual colonies of both mutants onto m9, m9 ornithine, and m9 l-argininosuccinate plates that you purchased from a reputable supplier. As expected, the arge mutant cannot grow on m9 unless ornithine is supplemented. Unexpectedly, the argg mutant can grow on all three plates, whether l-argininosuccinate is supplemented or not. What is the most plausible explanation for these unexpected results?
Answers
The most plausible explanation for the unexpected results is that the argg mutation occurs downstream of the arge mutation in the arginine biosynthetic pathway. The arge mutation has a defect in the step converting ornithine to citrulline, which can only be restored by supplementing ornithine to the growth media.
However, the argg mutant can grow on all three plates without the need for L-argininosuccinate supplementation. Arginine biosynthesis in E. coli is a multistep pathway. It begins with the enzyme N-acetylglutamate synthase (encoded by the argA gene), which catalyzes the formation of N-acetylglutamate.
In the next step, N-acetylglutamate kinase (ArgB) phosphorylates N-acetylglutamate to form N-acetylglutamyl phosphate. N-acetylglutamyl phosphate is then converted to ornithine by ornithine transcarbamylase (argF) and ornithine is further converted to citrulline by argininosuccinate synthase (argG) followed by argininosuccinate lyase (argH) to form arginine.
Therefore, it can be concluded that the arge mutation occurs at the step converting ornithine to citrulline while the argg mutation occurs at the step converting argininosuccinate to arginine. The arge mutation prevents the conversion of ornithine to citrulline while the argg mutation does not affect the conversion of argininosuccinate to arginine. Thus, it can grow on all three plates without the need for L-argininosuccinate supplementation.

Sam is investigating the factors that affect photosynthesis. She keeps some plants in the dark for 24–48 hours. They receive no light. What does this remove from the plants?
Answers
Keeping the plants in the dark for 24-48 hours removes the source of light from the plants.
Light is one of the essential factors required for the process of photosynthesis in plants.
During photosynthesis, plants use light energy to convert carbon dioxide and water into glucose and oxygen. This process takes place in specialized cell structures called chloroplasts, which contain the pigment chlorophyll that captures light energy.By depriving the plants of light for an extended period, the plants are unable to carry out photosynthesis. As a result, they are unable to generate the energy-rich molecules necessary for their growth, development, and survival.Without the presence of light, plants cannot perform the chemical reactions involved in photosynthesis and cannot produce the required carbohydrates and other organic compounds.Thus, the plant's source of light is removed by keeping them in the dark for 24 to 48 hours.

The brain dysfunction associated with autism spectrum disorder (ASD) can sometimes involve the cerebellum and sometimes involve the frontal cortex.
a. True
b. False
Answers
a. True is the correct answer.
What is ASD?Autism spectrum disorder (ASD) is a neurodevelopmental disorder that affects communication, social interaction, and behavior. The exact cause of ASD is not fully understood, but it is believed to involve a combination of genetic and environmental factors.
Brain imaging studies have shown that individuals with ASD often have structural and functional abnormalities in several areas of the brain, including the cerebellum and frontal cortex.
The cerebellum is involved in motor control, balance, and coordination, but research suggests that it may also play a role in higher cognitive functions, such as language, attention, and social interaction. The frontal cortex, on the other hand, is responsible for a range of executive functions, including decision-making, planning, and impulse control, as well as social cognition and emotional regulation.
The dysfunction associated with ASD in these brain regions can manifest in different ways, depending on the individual. Some individuals with ASD may have difficulty with motor coordination and balance, while others may have trouble with language and communication.
Some individuals may exhibit impulsivity, while others may struggle with social interaction and emotional regulation. Therefore, it is true that the brain dysfunction associated with ASD can sometimes involve the cerebellum and sometimes involve the frontal cortex.

g imagine that in the future we discover a set of genes that is largely responsible for causing aging in humans. also, imagine that we can alter these genes in some way so that we live longer. considering antagonistic pleiotropy, why might this be a concern?
Answers
Antagonistic pleiotropy is a genetic phenomenon where a single gene affects multiple traits, with positive effects on some traits and negative effects on others. In the case of aging, it is possible that the set of genes responsible for causing aging in humans also have positive effects on other aspects of health and fitness, such as reproductive success and immunity.
If we were to alter these genes in some way to extend lifespan, it is possible that we would inadvertently disrupt the positive effects of these genes on other traits. For example, if a gene that promotes cellular repair also increases the risk of cancer, altering it to extend lifespan could also increase the risk of cancer. Similarly, if a gene that enhances immunity also increases inflammation and tissue damage, altering it to extend lifespan could also compromise the immune system and increase susceptibility to infections.
Thus, the concern with altering the set of genes responsible for causing aging is that we may be trading off lifespan for other aspects of health and fitness. This is not to say that we should not pursue research on extending lifespan, but rather that we should be mindful of the potential trade-offs and strive to understand the full scope of the genetic and physiological mechanisms involved in aging before attempting to manipulate them.

In most of green plants, photosynthesis takes place in the___________.
Answers
In most of green plants, photosynthesis takes place in the chloroplasts. Photosynthesis is the process through which plants absorb water and carbon dioxide from the soil and atmosphere.
In contrast to the carbon dioxide, which is reduced within the plant cell and obtains electrons, water is oxidised within the cell of the plant. Due to this, carbon dioxide and water are converted into glucose and oxygen, respectively. The photosynthesis process can be carried out by such plants' green stems. Photosynthesis may typically be carried out by plants as long as they have green parts. Chloroplasts, which are involved in photosynthesis, are what give plants their characteristic green hue.
