what are the steps for dna replication?
Answers
Answer:
the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment.
Answer:
Process below
Explanation:
DNA replication is the process by which a cell copies its DNA in order to produce new cells. The steps of DNA replication are as follows:
The DNA double helix unwinds and separates into two single strands.An enzyme called helicase unwinds the DNA at the replication fork, breaking the hydrogen bonds between the nitrogenous bases and separating the two strands.Another enzyme called primase adds short RNA primers to the single strands of DNA. These primers provide a starting point for the synthesis of new strands.An enzyme called DNA polymerase begins adding new nucleotides to the single strands of DNA, using the existing strands as a template. DNA polymerase adds nucleotides to the 3' end of each strand, moving in the direction of the 5' end.The newly synthesized strands are joined together by an enzyme called ligase, which seals any gaps between the nucleotides.Once replication is complete, the cell has two identical copies of the original DNA molecule. These copies are used to create new cells, ensuring that each cell has the same genetic information as the original cell.Related Questions
consider the total breakdown of the glycogen structure below. assuming each glycosidic linkage can be broken down completely and the resulting products are fed through glycolytic metabolism.
Answers
The complete breakdown of glycogen structure results in the production of glucose molecules.
Glycogen is a complex carbohydrate composed of many glucose units linked together by glycosidic bonds. During the breakdown of glycogen, each glycosidic bond is cleaved by the action of glycogen phosphorylase, releasing a single glucose molecule.
The breakdown of glycogen occurs through the action of the enzyme glycogen phosphorylase, which cleaves the glycosidic bonds and releases individual glucose molecules. These glucose molecules can then be used as a source of energy for the body through cellular respiration.
Once the glucose molecules are produced, they can be fed into the glycolytic metabolism pathway, which results in the breakdown of glucose into pyruvate. This process generates energy in the form of ATP and is an important source of energy for the body, particularly during intense physical activity.

Using a sterile, plastic urine collection bag with a hypoallergenic skin adhesive is the proper approach to collect a kid urine sample. Before taking the sample, the perineal area needs to be thoroughly cleaned. The urethra must be encircled by the adhesive opening. Empty the bag into a 24-hour specimen container if one is required, then fasten a new bag.
A laboratory test called a 24-hour urine collection is performed to evaluate the amount of urine in a sample and assess kidney function. A 24-hour urine collection often goes like this: One or more containers will be provided to you so that you can collect and store your urine. Usually, a brown plastic container is utilised.

Meiosis worksheet define the following terms: homologous chromosome
Answers
A homologous chromosome is a pair of two chromosomes that typically includes one inherited from the mother and one from the father.
A pair of chromosomes known as homologous chromosomes has the same genetic material but may have various gene variants (alleles). They are produced when a single chromosome doubles itself during DNA replication and are comparable in size, structure, and gene content. During meiosis, homologous chromosomes join up, cross across to exchange genetic material, and then split into various cells. This technique aids in genetic information shuffle, resulting in variety in the progeny. The homologous chromosomes are essential for sexual reproduction because they make sure that each child inherits a combination of genes from both parents. Each human cell contains 46 chromosomes in total since there are 23 pairs of homologous chromosomes.

from which component of the light-dependent reactions does nadph form most directly? group of answer choices photosystem ii photosystem i cytochrome complex atp synthase
Answers
The most direct formation of NADPH occurs in the photosystem I component of light-dependent processes.
what is light dependent reactions?
The energy store molecule ATP and the reduced electron carrier NADPH are two molecules produced by the light-dependent processes that are required for the next phase of photosynthesis. The light processes are crucially influenced by photosystems, sizable protein and pigment (light-absorbing molecule) complexes that are designed to capture light. The two different kinds of photosystems are the PSI and the PSII.
In other words, the electron transfers between PSII and PSI and between PSI and NADPH are only energetically "downhill" (energy-releasing, and hence spontaneous) because the electrons in P680 and P700 are given a boost to extremely high energy levels by the absorption of energy from light.When a photon from PSII strikes PSI and ignites it, NADP (oxidised adenosine diphosphate phosphate) will reduce to NADPH. The most traditional method of NADPH has to be PSI.

As a result of rising temperatures, what changes could someone most likely predict about future generations of polar bears?
They will grow thicker, warmer coats.
They will grow thinner, darker fur.
They will lose their ability to swim.
They will become herbivores.
Answers
Answer:
They will grow thinner, darker fur.
Explanation:
This is because as temperatures rise, the Arctic sea ice melts, which makes it more difficult for polar bears to hunt their main prey, seals. As a result, they are likely to experience food shortages, which can lead to malnutrition and weight loss, resulting in thinner bodies. Additionally, as the sea ice melts, polar bears are forced to swim longer distances, which can also lead to increased energy expenditure and further weight loss. Therefore, it is unlikely that polar bears will grow thicker, warmer coats in response to rising temperatures.
