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.
Explanation:
Flagellum, plural flagella, hairlike structure that acts primarily as an organelle of locomotion in the cells of many living organisms. Flagella, characteristic of the protozoan group Mastigophora, also occur on the gametes of algae, fungi, mosses, slime molds, and animals.
Flagellum Definition
A flagellum is a microscopic hair-like organelle used by cells and microorganisms for movement. The word flagellum in Latin means whip, just like the whipping motion flagella (plural) often use for locomotion. Specialized flagella in some organisms are also used as sensory organelles that can detect changes in temperature and pH.

c-Fos is a proto-oncogene that is the homolog of the retroviral oncogene v-fos. It was first discovered in rat fibroblasts as the transforming gene of the FBJ MSV.</span>
