In the polymerization of DNA, a phosphodiester bond is formed between a phosphate group of the nucleotide being added and which of the following atoms or molecules of the last nucleotide in the polymer?AThe 5' phosphate group.BC6.CThe 3' OH.DA nitrogen from the nitrogen-containing base.

Sagot :

The last nucleotide in the polymer is C)The 3' OH

A phosphodiester bond is produced when two of the hydroxyl groups in phosphoric acid engage with the hydroxyl groups on other molecules to establish two ester bonds. Because they provide the structure for the nucleic acid strand, phosphodiester bonds are essential for all life on Earth.

When nucleotides are integrated into DNA, a covalent bond between the 3'-OH group and the 5'-phosphate group of one nucleotide results in the formation of phosphodiester bonds between adjacent nucleotides.

A free 3'OH group is necessary for replication, but when the two chains separate, it does not exist. Replication is initiated using the primer's free 3'OH after it is used to make RNA primers. The replication fork only moves in one direction, whereas DNA replication only happens in the 5' to 3' direction.

In the polymerization of DNA, 3' OH is the last nucleotide in the polymer.
