Answer:

A mutation is a change in a DNA sequence. Mutations can result from DNA copying mistakes made during cell division, exposure to ionizing radiation, exposure to chemicals called mutagens, or infection by viruses.

Somatic hypermutation of V genes ​
zaharov [31]

Answer:

Somatic hypermutation is a process in which point mutations build up in the antibody V-regions of both the heavy and light chains.

This process occurs at rates that are about 106-fold higher than the background mutation rates observed in other genes.

It allows B cells to mutate the genes that they use to produce antibodies. This then ensures the B cells to produce antibodies that are better able to bind to bacteria, viruses and other infections.

The binding of a compound to an enzyme is observed to slow down or stop the rate of the reaction catalyzed by the enzyme. Increa
Setler79 [48]

Answer:

The correct answer is A the compound is a competitive inhibitor

Explanation:

Competitive inhibitor competes with the substrate to bind to the active site of the target enzyme and after binding to the active site the inhibitor slow down or stop the reaction catalyzed by that enzyme.

          Competitive inhibitor basically effects the Km value of the enzyme thus decreasing the activity of the later.

           Increasing the substrate concentration displace the inhibitor from the enzyme"s active site thus reducing the inhibitory effects of the later thus increasing the activity of the enzyme.

In sweet pea, red flower color is controlled by two genes involved in the anthocyanin pathway, A and B. Both genes are required
Alex787 [66]

Answer:

The dihybrid ratio we expect in the offspring is 9:7.

Explanation:

This is an example of complementary gene interaction, which is the non allelic interaction or genes, where the prominent genes at heterozygous loci may complement each other by complementing recessive alleles at the respective loci.

So in this case of  complementary gene interaction, the individuals that are A-bb or aaB- or aabb will have the same set of observable features (phenotype) but only A-B- individuals will how the dominant phenotype.

Label the stages of mitosis for every image (1-10) I will mark brainliest:)
Romashka-Z-Leto [24]

Answer:

Mitosis is the process in which the nucleus of a eukaryotic cell divides. During this process, sister chromatids separate from each other and move to opposite poles of the cell. This happens in four phases, called prophase, metaphase, anaphase, and telophase
