Question

question 9
you create a hybrid transgene containing dna from a human and a mouse. which of the following factors would most strongly affect when, where, and how much protein is expressed from that gene?
a the genes regulatory region
b the genes coding sequence
c the age of the host animal
d on which chromosome the gene resides
e the number of alleles

Explanation:

The gene's regulatory region controls gene expression, determining when, where, and how much protein is made. The coding sequence determines the amino - acid sequence of the protein, not the expression levels. Age of the host animal, chromosome location, and number of alleles have less direct impact on the temporal, spatial, and quantitative aspects of gene expression compared to the regulatory region.

Answer:

A. the gene's regulatory region
