What is the role of helicase in DNA replication?

• It assembles nucleotides into DNA strands.

• It unwinds and separates DNA strands.

• It synthesizes RNA primers.

• It repairs damaged DNA.

How are nucleosomes formed?

• By folding DNA into a double helix.

• By linking DNA strands with RNA.

• By wrapping DNA around histone proteins.

• By coiling DNA strands into a helix.

What is the function of microtubules during cell division?

• They form the cell membrane.

• They synthesize DNA.
