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.
True. Since electron microscopes use electrons instead of light, it can magnify up to 500,000 times of it’s actual size.
