What enzyme helps in the replication if DNA?

Solution

The enzymes that are involved in DNA replication of

Helicase:

Unzip or unwinde DNA helix at the replication fork resulting in single strands to be replicated.

Primase:

This enzyme synthesizes RNA primer to act as template for future okazaki fragments to build.

DNA polymerases:

These copy DNA sequences by using one strand of the DNA as template. The require a primer that is complementary to the template. Ex: DNA polymer 1& 11 which are repair enzyme.

DNA polymerase 3 helps in synthesizing nucleotides onto leading end in 5\'-3\' direction.

Ligase:

Define line helps in burning the okazaki fragments.

Telomerase:

It includes a molecule of RNA which acts as template for nuclear segments and it helps in catalyzing the lengthening of telomeres.

Nuclease:

This enzyme cut the unwanted or defective segments from the DNA sequence.

Topoisomerase:

During unwinding of the double helix this enzyme reduces single strand nick in the DNA enabling it to coil and that relieve the strain.
