Question

In bacterial DNA replication of the lagging strand, __________ is required for the synthesis of a new DNA strand whereas __________ is required for removing the RNA primer and replacing it with DNA nucleotides.

Answer 1

Answer:

In bacterial DNA replication of the lagging strand,DNA polymerase III is required for the synthesis of a new DNA strand.

whereas DNA polymerase I is required for removing the RNA primer and replacing it with DNA nucleotides.

Explanation:

Replication: is a process by which two identical copies of DNA are produced from the original DNA molecule.

Bacterial DNA replication take place in three steps

• Initiation

• elongation

• termination.

DNA polymerase III is an enzyme that is responsible for DNA synthesis in bacteria and to carry out the '5-3' polymerase function.

DNA polymerase consists of

• pol III core: carry the polymerase activity and proofreading activity of the nucleotides which are mispaired.

• beta sliding clamp: increase the DNA synthesis rate.

• clamp loading complex. promote DNA replication.

DNA polymerase I: function is to join the Okazaki fragments by removing the RNA primer and replacing it with nucleotides and to repair the damage the DNA.
