Question

DNA contains the template needed to copy itself, but it has no catalytic activity in cells. What catalyzes the formation of phosphodiester bonds between adjacent nucleotides in the DNA polymer being formed?A) RibozymesB) DNA polymeraseC) ATPD) Deoxyribonucleotide triphosphates

Answer 1

Answer:B. DNA polymerase

Explanation:

DNA polymerase is the enzyme that catalyzed the formation of phosphodiester bonds between adjacent nucleotides in the DNA polymer formed.

Answer 2

Answer: The correct answer to the question is option B.

DNA POLYMERASE

DNA polymerase catalyzes the formation of phosphodiester bonds between adjacent nucleotides in the DNA polymer being formed

Explanation: DNA Replication, the formation of a phosphodiester bridge is catalyzed by DNA polymerases.

DNA polymerases catalyze the formation of a phosphodiester bond efficiently only if the base on the incoming nucleoside triphosphate is complementary to the base on the template strand,During polymerization of nucleotides to form nucleic acids, the hydroxyl group on the phosphate group attaches to the 3' carbon of a sugar of one nucleotide to form an ester bond to the phosphate of another nucleotide. The reaction forms a phosphodiester linkage and eliminates a water molecule. In DNA and RNA, the phosphodiester bond is the linkage between the 3' carbon atom of one sugar molecule and the 5' carbon atom of another, deoxyribose in DNA and ribose in RNA. Strong covalent bonds form between the phosphate group and two 5-carbon ring carbohydrates (pentoses) over two ester bonds.

The phosphodiester bond, which links the sugar molecules and phosphate molecules in the backbone, is one of the most crucial components for building DNA and RNA because it maintains the integrity of the genetic code and allows for life on this planet.
