From a single fertilized ovum undergoing a series of rapid cell divisions, a human infant develops. The embryonic cells become s
pecialized for a variety of functions. Which of these statements best describes how different cell types develop? A. Each cell type contains only the active parts of the DNA needed for that cell type.
B. Each cell has multiple copies of DNA that are affected in different ways by the environment to change the function of the cell at regular intervals.
C. Each cell has an identical copy of DNA with enzymes controlling the expression of specific genes, leading to a variety of cells.
D. Each cell type has only one chromosome containing thr DNA needed for that cell type.
<span>Bacterial genome is prone to mutational changes due to its simple nature and less efficient DNA repair mechanisms compared to humans, thus it has more chances of obtaining new genetic traits.</span>
