Question 14

A culture of synchronous animal cells is treated with a chemical agent that specifically inhibits mitochondrial translation, preventing the duplication of mitochondria and cell growth. This treatment is administered immediately after the completion of cytokinesis.

In which phase of the cell cycle will these cells accumulate, and what will be their relative DNA mass compared to a cell in the second growth ( $G_2$ ) phase?

first growth ( $G_1$ ) phase, with half the DNA mass of a cell in the second growth ( $G_2$ ) phase

first growth ( $G_1$ ) phase, with twice the DNA mass of a cell in the second growth ( $G_2$ ) phase

second growth ( $G_2$ ) phase, with half the DNA mass of a cell in the first growth ( $G_1$ ) phase

synthesis ( $S$ ) phase, with half the DNA mass of a cell in the second growth ( $G_2$ ) phase
