Answer:
hello your question lacks the required option below are the missing options
A) The gene for insulin is a sequence of five different molecular bases while the gene for testosterone is a sequence of only four different molecular bases.
B) The gene for insulin is replicated in vacuoles, while the gene for testosterone is replicated in mitochondria
C) The gene for insulin has a different sequence of molecular bases than the gene for testosterone.
D) The gene for insulin is turned ON in liver cells, but the gene for testosterone is not
answer : The gene for insulin has a different sequence of molecular bases than the gene for testosterone ( C )
Explanation:
The statement that indicates the difference between the gene that codes for insulin and a gene that codes for testosterone is ; The gene for insulin has a different sequence of molecular bases than the gene for testosterone.
Genetic codes are determined basically by the four types of nitrogen bases contained in the molecules of the DNA ,
