goldfiish [28.3K]

Answer:

C. A-T rich; initiator

Explanation:

Replication origins have A-T rich DNA sequences that attract initiator proteins.

Replication origin is the DNA sequence where replication is initiated in a genome. The replication origin sequences is rich in adenine (A) and thymine (T) bases because it is easier to break the bonds between the bases compared to the bonds between guanine and cytosine. adenine (A) and thymine (T) bases have two bonds joining them as against three bonds between guanine and cytosine

The initiator proteins recognizes  DNA sequences in the replication origin and helps to initiate DNA replication.
