Scientists who study the cell cycle use fluorescent dyes and lasers that enable them to measure the DNA content of individual cells. They can count the number of cells with 2N and 4N DNA content, as well as in between 2N and 4N (greater than 2N, but not quite 4N yet). a. In what phase(s) of the cell cycle will cellshave 2N DNA content?
b. In In what phase(s) of the cell cycle will cellshave 4N DNA content?
c. In what phase(s) of the cell cycle will cellshave more than 2N but less than 4N DNA content?
