Question

A normal sequence of DNA bases in a single

human skin cell is CATGGC. If this sequence
replicates in this cell and becomes GATGGC,
this alteration will most likely be passed to
(1) every cell that develops from it
(2) all human body cells
(3) offspring of the human
(4) all skin cells of this person

Answer 1

The answer is (1). The skin cell is the terminal differential cell. So it will not differentiation again but can divide. Then it will not pass to the offspring and only can pass to the cells that develops from it.
