Answer:
the answer is all of the above
Answer: Ribose is synthesized from glucose and other monosaccharide molecules in living cells by a process known as pentose phosphate pathway. The pentose phosphate pathway is a series of chemical reactions taking place in the cytosol of cells.
True
Changes in the transcription of mRNA or the translation of a polypeptide are not considered to be mutations because they are not permanent changes to the cell.
Explanation:
The half-life of mRNA and proteins is short. mRNA has an average of 10 hours of life span while proteins have an average of several days. Therefore mutation in these biomolecules will only persist as long as this mutated mRNA of protein exists. After its life-span, the molecule is degraded and replaced by a non-mutated mRNA or proteins. This is because the piece of DNA that codes for the mRNA and subsequent protein is not mutated. A mutation on DNA is the permanent kind of mutations because DNA is a highly stable molecule that stores information about the cell.

Answer:
Comparing DNA
Explanation:
Darwin could compare only the anatomy and embryos of living things. Today, scientists can compare their DNA. Similar DNA sequences are the strongest evidence for evolution from a common ancestor.
