Apart of the promoter, called the tata box, is said to be highly conserved in evolution. which might this illustrate? a. the sequence evolves very rapidly. b. the sequence does not mutate. c. any mutation in the sequence is selected against. d. the sequence is found in many but not all promoters. e. the sequence is transcribed at the start of every gene.

c. Any mutation in the sequence is selected against.

Explanation:

When a gene sequence is said to be highly conserved during evolution, it means that it has a low rate of mutations and mutations in this sequence are not favored by the evolutionary forces. Evolutionary forces such as natural selection favor the organisms with the non-mutated sequence. Since the promoter sequence TATA box is highly conserved, evolutionary forces do not favor the phenotypes having mutations in this sequence. On the other hand, the organisms having the wild type TATA box sequence are favored during evolution.

hey there!

so, when you eat, your teeth chew and grind food into smaller pieces. this is mechanical digestion. then reactions aided by digestive enzymes break down large food molecules into smaller molecules. this is chemical digestion. the two processes change the food into simpler substances that can be used by the body for raw materials and energy.

hope this
