What is the function of mRNA (messenger RNA)?

Answers

Answer 1

Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts; ribosomal RNA (rRNA) molecules form the core of a cell's ribosomes (the structures in which protein synthesis takes place); and transfer RNA (tRNA) molecules carry amino acids to the ribosomes during protein.

Answer 2

mRNA is the messenger RNA found in all the living organisms. This RNA is responsible for the synthesis of proteins. mRNA translates the coding sequence from the DNA of an organism into the proteins.

What is Translation?

Translation is the process of synthesis of proteins in the ribosomes (rough endoplasmic reticulum) of the cell. In this process, the mRNA formed during the transcription of DNA is used for the production of all types of proteins in the cell.

The role of mRNA is to carry the information of proteins from the DNA into the cell's nucleus to the cell's cytoplasm, where the protein-synthesis machinery reads the mRNA sequence encoded by the DNA of the organism and translates each of the three-base codons into their corresponding amino acid in a growing polypeptide chain which forms the protein.

Show the reciprocal cross​: A red-eyed female (homozygous) and a white-eyed male. How many offspring will have white eyes and what is their sex?

Answers

When we see the reciprocal cross between a red-eyed female (homozygous) and a white-eyed male,we observe that none of the offspring will have white eyes. Additionally, the sex of the offspring will be half male and half female since the ratio of males to females is 1:1.

The reciprocal cross for a red-eyed female (homozygous) and a white-eyed male can be shown as follows:Female (XrXr) x Male (XwY). Females have two X chromosomes and males have an X and a Y chromosome. Red eyes are dominant to white eyes; therefore, we use Xr to represent red eyes and Xw to represent white eyes.

The offspring are as follows:All F1 females are heterozygous (XrXw).All F1 males are hemizygous (XrY).The F1 generation will have red eyes since the dominant allele is present.

None of the F1 individuals will have white eyes as the recessive allele is not present in the F1 generation.

2.) genes, located on chromosomes, found in the nucleus

What are traits?

Traits are passed from parents to offspring and are determined by genes, which are located on chromosomes in the nucleus of cells.

Chromosomes are long, thread-like structures that are found in the nucleus of cells. They are made up of DNA and proteins and carry the genetic information that determines an individual's inherited traits. Each chromosome contains many genes, which are specific segments of DNA that contain the instructions for making proteins. Proteins are molecules that perform a wide range of functions in the body, including building and repairing tissues, regulating chemical reactions, and transmitting nerve impulses.

Genes are located on chromosomes in the nucleus of cells and are responsible for determining an individual's inherited traits, such as eye color, hair color, and blood type. When cells divide, the chromosomes are replicated and the genes are passed on to the daughter cells. This is how traits are passed from parents to offspring.

Explain how different links can show a relation between two species. Describe evidence that shows other correlations and causations between the species.

Answers

Different links show relationships between two species. In the scientific world, there are three types of links, including mutualism, parasitism, and commensalism.

Mutualism is a relationship in which both species benefit. Parasitism is where one species benefits, and the other is harmed. Commensalism is a relationship in which one species benefits, and the other is not harmed or helped.One example of a mutualistic relationship is the bee and flower relationship. Bees collect nectar and pollen from flowers for their food, while at the same time, the bee helps in pollination. The bee gets food from the flower, and the flower is pollinated. This is a mutualistic relationship. A parasitic relationship is the relationship between tapeworms and humans. Tapeworms live inside the host and get their food from the host, thereby, causing harm to the host. Evidence that shows correlation and causation between the species includes physical changes in the organism or adaptations to the environment. For example, an animal that feeds on a certain plant may evolve to have a longer tongue to reach the nectar of that plant. In summary, different links show relationships between species, including mutualism, parasitism, and commensalism. The evidence for the correlation and causation between species includes physical changes or adaptations in the organism or environment.

What effects do you think that the loss of coastal fens has had on Michigan coastlines, coastal properties, plants and wildlife?

Answers

The loss of coastal fens in Michigan has had significant effects on the state's coastlines, coastal properties, plants, and wildlife.

Coastal fens are unique wetland habitats that provide important ecological functions and support a diverse range of plant and animal species.The loss of coastal fens has resulted in the degradation and erosion of Michigan's coastlines. Fens act as natural buffers, absorbing wave energy and reducing the impact of storms and high lake levels. Without the presence of fens, coastal areas are more susceptible to erosion, leading to shoreline retreat, loss of land, and damage to coastal properties.The disappearance of coastal fens has had a negative impact on the plant communities in the region. Fens are home to a variety of specialized plant species that are adapted to the unique hydrological and nutrient-rich conditions of these habitats. The loss of fens has resulted in a decline in plant diversity and the displacement of native species by invasive plants, disrupting the natural balance of coastal ecosystems.The loss of coastal fens has had implications for wildlife populations. Fens provide critical habitat for a wide range of species, including amphibians, reptiles, birds, and mammals. The loss of these habitats has led to the loss of nesting sites, feeding areas, and migration corridors for many species. This can have cascading effects on the overall biodiversity and ecological functioning of coastal ecosystems.The loss of coastal fens in Michigan has resulted in increased coastal erosion, decreased plant diversity, and the disruption of wildlife habitats. Efforts to protect and restore these imperiled habitats are crucial for preserving the ecological integrity and resilience of Michigan's coastlines and supporting the diverse array of plants and wildlife that depend on them.

Answers

Answer:

Genes that express 50% of recombination frequency or more are not linked genes. They might be in different chromosomes or located in the same one, but too far from each other.    

Explanation:

Genes are physically located in chromosomes. Many genes segregate independently after crossing-over because they are located far away from each other. But some other genes are too close, and they do not segregate independently. These are the linked genes that do not exhibit an independent distribution, and they inherit together more frequently.

We need to know that 1% of recombination frequency = 1 map unit = 1cm. And that the maximum recombination frequency is always 50%.

When the recombination frequency is inferior to 50%, genes are linked. If it is equal or superior, they are not linked. Genes are located far enough from each other to assort independently.

Genes that express 50% of recombination frequency or more are not linked genes. They might be in different chromosomes or located in the same one, but too far from each other.
