In Rapidly Dividing Cells,expression of BRCA1 and BRCA2 Genes Is

Question

In rapidly dividing cells,expression of BRCA1 and BRCA2 genes is the highest during the ____.
A) mitosis to cytokinesis transition
B) G1/S transition and into S phase
C) G2/mitosis transition
D) S/G2 transition
E) metaphase to anaphase transition

Accepted Answer

The BRCA1 and BRCA2 genes are involved in DNA repair, particularly during DNA replication. Their expression peaks during the G1/S transition and into the S phase, when DNA replication occurs, to ensure genomic integrity.
