Answer:

To allow transcription enzymes to access the DNA strand

Explanation:

The DNA double helix is made up of two complementary strands wound around each other, and tightly packaged as chromosomes.

DNA and RNA polymerases promote either DNA or RNA synthesis by attaching free nucleases to parent strands (a), which are then unwound and isolated by helicases (b). DNApolys synthesize DNA in a 5'-3 ' direction; owing to its restricted flow, there are only two types of replication: continuous from the point of differentiation of chromosomes, fork, and discontinuous from the fork.
