What is the Function of Host Factor During the Replication

Question

What is the function of Host Factor during the replication of the Qb RNA genome?
A) It delays the folding of the RNA into its final secondary structure.
B) It makes the 3' end of the genome more accessible to the replicase enzyme.
C) It adds a non-template A nucleotide to the 5' end of the minus strand.
D) It facilitates binding of the replicase protein to the coat protein start codon.
E) It prevents binding of the replicase enzyme to the 5' end of the genome.

Accepted Answer

Host Factor helps in unwinding and denaturing the 3' end of the Qb RNA genome, making it more accessible to the replicase enzyme, which facilitates replication.
