Question

DNA replication requires
A. DNA polymerase
B. DNA ligase
C. RNA polymerase
D. All of the above

Answer 1

Hint: DNA is deoxyribonucleic acid. It carries the genetic code of organisms. With the help of the DNA replication process, genetic code is transferred from the parent cell to daughter cells. It performs a crucial role in the cell division process especially in the growth and repair of damaged tissues.

Complete Answer:
1) DNA polymerase is a polymerizing enzyme that has to polymerize and to exonuclease editing activities. It adds deoxyribonucleotides to free hydroxyl gathering of groundwork to incorporate new DNA strands.

2) The DNA ligase enzyme consolidates two fragments using a phosphodiester bond between hydroxyl toward the finish of one end and phosphate at the end of another section.

3) RNA polymerase fills in as primase during DNA replication and blends RNA/DNA groundwork which is an abandoned segment and has a free hydroxyl group to facilitate the expansion of deoxyribonucleotides by DNA polymerase enzyme.

Therefore, the correct option is D i.e, all of the above.

Note: One massively long DNA molecule forms each of the chromosomes of an organism, of them in a human. The essential living unit is a single cell. A cell rises into multiple cells through the sequential repetition of a process called cell division.
Before every division, new copies must be made of each of the numerous molecules that structure the cell, including the duplication of all DNA molecules. DNA replication is the name given to this duplication cycle, which enables an organism to pass hereditary information from one generation to another.
