Question

in which phase does the cell form sister chromatids that are linked at their midpoints?
g₂
mitosis
g₁
s
cytokinesis

Explanation:

During the S (synthesis) phase of the cell cycle, DNA replication occurs. Each chromosome is replicated, and the two identical copies (sister chromatids) are linked at the centromere (midpoint). In \(G_1\) phase, the cell grows and prepares for DNA replication. In \(G_2\) phase, the cell prepares for mitosis. Mitosis is the process of nuclear division, and cytokinesis is the division of the cytoplasm.

Answer:

S
