How does skin color relate to protein synthesis

1 answer:

4 0

Answer: Many Genes, Many Proteins. The expression of a multitude of genes is required for the characteristic known as skin color. This expression results in a continuous palette of skin color. The skin pigments, eumelanin and pheomelanin are synthesized in melanosomes, which form in melanocytes.

You must draw a Punnett square and work out these problems to get the correct answers. In cats, long-hair (H) is dominant to sho

Lana71 [14]

Answer:

The correct answer is -

Genotypes: 1 heterozygous dominant: 1 recessive

Phenotypes: 1 long hair cat: 1 short hair cat

probability: 50% chances of both long and short hair cats

Explanation:

It is given that long hair is a dominant represented by H, over the short hair represented by h. In the cross of a heterozygous cat for long hair with a cat with short hair, would produce H, h and h, h gametes respectively.

Cross: Hh × hh

H h

h Hh hh

In this Punnett, there are two heterozygous long hair offspring produced and two short-hair cats.

So, Genotypes: 1 heterozygous dominant: 1 recessive

Phenotypes: 1 long hair cat: 1 short hair cat

probability: 50% chances of both long and short hair cats

How can DNA be useful in phylogeny? Question 14 options: A) DNA from every organism in a clade is sequenced to identify genetic

Delvig [45]

Answer:

The correct answer is - option B. DNA sequences from different species can be compared, giving us more information about their evolutionary relationships.

Explanation:

The study of the evolution of a species in a longer period of time and its evolutionary relation with other species is phylogeny. DNA is the basis of the molecular phylogeny of a species to find out the evolution of species.

Genetic mutations, a sequence of nucleotides, and other information of DNA helps in the establishment of divergence from common ancestry. By comparing the information it gives an idea about the evolutionary ancestry of two or more species.

Species a diverged from species b 60,000 years ago. On a particular gene, they have 15 nucleotide differences. How many nucleoti

a_sh-v [17]

The given question says that b species diverged around 60,000 year ago from species a. Since the divergence, they have a nucleotide difference of 15 nucleotide.

We need to find out the nucleotide difference in another 240,000 year, which means a total of 300,000 year since divergence.

The nucleotide difference in 60,000 years = 15 nucleotide.

The nucleotide difference in 1 year = $\frac{15}{60,000}$ nucleotide.

The nucleotide difference in 300,000 years = $\frac{15}{60,000}\times 300,000$ nucleotide.

The nucleotide difference in 300,000 years = 75 nucleotide.

Hence, after another 240,000 years or 300,000 years since divergence, the species and species b would show a difference of 75 nucleotide.

In another 240,000 years, there would be 60 nucleotide difference, as 15 of the nucleotide are already different in initial 60,000 years from the total of 75 nucleotide difference in 300,000 years. So, 60 (75-15) nucleotide difference would be observed in next 240,000 years.

What structures have rna

Ksivusya [100]

Structurally, DNA and RNA are nearly identical. As mentioned earlier, however, there are three fundamental differences that account for the very different functions of the two molecules. RNA has a ribose sugar instead of a deoxyribose sugar like DNA. RNA nucleotides have a uracil base instead of thymine.
