Answer: Acetyl-CoA
Explanation:
Acetyl-CoA can be obtained from the pyruvate, the end product of aerobic glycolysis. Also, Acetyl-CoA is the one of the starting materials of citric acid cycle.
For lipid synthesis, biotin carries activated CO2 that is incorporated into acetyl-CoA to form Malonyl-CoA, which is then elongated to yield various lipids of different length.
Thus, Acetyl-CoA is the building block of lipid synthesis
Answer:
Option (D).
Explanation:
Different DNA polymerase are present in eukaryotes that are necessary for the replication of the DNA. DNA polymerase composed of four subunits : POLD2, POLD1, POLD4, and POLD3.
The DNA polymerase delta are involved in the DNA synthesis. This polymerase has both the exonuclease activity and proofreading ability of newly synthesized DNA.
Thus, the correct answer is option (d).
