Question

Which of the following is TRUE regarding nucleosome formation during DNA replication?

a) Nucleosomes are dismantled during replication.
b) Nucleosomes are replicated as intact structures.
c) Newly synthesized DNA is immediately wrapped into nucleosomes.
d) Nucleosomes form only after DNA synthesis is complete.

Answer 1

Nucleosomes are dismantled during replication, and newly synthesized DNA is immediately wrapped into nucleosomes.

Step-by-step explanation:

During DNA replication, nucleosomes are dismantled and then reassembled. This process allows for the replication of DNA while maintaining the structural integrity of the nucleosomes.

After the DNA is replicated, newly synthesized DNA is immediately wrapped into nucleosomes to form chromatin. Nucleosomes play a crucial role in compacting and organizing the DNA in the cell.

Therefore, the correct answer is a) Nucleosomes are dismantled during replication.
