Question

when measuring the dna content in a mitotically active tissue, you note that a particular cell has half as much dna as some of the others. the cell is most likely in which phase? question 22 options: g2 metaphase g1 anaphase prophase

Answer 1

A cell with half as much DNA as others in a mitotically active tissue is likely in the G1 phase, where the DNA has not yet been replicated.

Step-by-step explanation:

If we observe that a cell has half as much DNA as others in a mitotically active tissue, it suggests that the cell is likely in the G1 phase of the cell cycle. During the G1 phase, the cell undergoes growth and prepares for DNA replication but has not yet duplicated its DNA, as it does in the subsequent S phase. Given this information, cells in other phases such as G2, metaphase, anaphase, and prophase will have a full content of DNA because DNA replication has already occurred during S phase, or they are engaged in the process of mitosis where the replicated DNA is divided between two daughter cells.
