Question

Quizplus · Accepted Answer

CENP-A is not involved in DNA replication licensing during S phase. It is a histone H3 variant associated with centromeres and is involved in chromosome segregation rather than DNA replication licensing. DNA replication licensing involves the assembly of pre-replication complexes at origins of replication during G1 phase, ensuring that each segment of the genome is replicated once and only once per cell cycle. ORC, MCM proteins, and helicase loaders are all components of this process, while geminin regulates it by inhibiting the re-assembly of pre-replication complexes once DNA replication has initiated.
