The hydrochloric acid produced by the stomach for digestion.
Explanation:
Due to the hernia, there is poor sphincter control thus allowing backflow of the acid into the eaophagus
The correct question with the options would be:
During which part of the cell cycle is DNA polymerase most active?
a. G1 phase of interphase
b. mitosis
c. S phase of interphase
d. G2 phase of interphase
e. cytokinesis
The correct answer is c. S phase of interphase.
The replication of the entire genome or the whole DNA occurs during the S-phase or also called synthesis phase. Therefore, the enzyme is DNA polymerase which carries out the replication of DNA shows its maximum activity. The DNA polymerase is active in various cell cycle checkpoints to detect the DNA damage but the repair action of DNA polymerase involves only a small region of DNA as compared to the whole genome during the S-phase.
b. an embryonic cell is the answer
