Answer:

The correct answer is option C. "pleiotropy".

Explanation:

Pleiotropy is a characteristic that defines a gene that is responsible for the development of multiple traits, which often seem to be unrelated. Sickle-cell disease is an example of a disease caused by the mutation of a pleiotropic gene, resulting in the person developing red levels, blood clots, and strokes. Other example is the disease phenylketonuria, at which the affected person suffers from a mental disorder and reduced hair and skin pigmentation by a single mutation in a single gene on chromosome 12.

How many nucleotides <br> are in the gene acc tta ggc cct tca
noname [10]
15

Each one of those letters represents a nucleotide. So to find out how many nucleotides are in the gene, just count them

However, keep in mind that this only represents 1/2 strands that make up DNA. If you are supposed to include the other strand, simply double 15, and there would be 30 nucleotides total. However, only 1 strand is actually required in order for protein synthesis to work, so I think it's just 15.
