What would you like to do?

Is topoisomerases belong to restriction enzymes?

already exists.

Would you like to merge this question into it?

already exists as an alternate of this question.

Would you like to make it the primary and merge this question into it?

exists and is an alternate of .

Topoisomerase is not a restriction enzyme but an enzyme that keeps unwound DNA from tangling while it is being replicated.

What are restriction enzymes?

Restriction enzymes (also known as restriction endonucleases) are proteins which cut DNA up at specific sequences in the genome. For example, the commonly used restriction end

What is a restriction enzyme?

A restriction enzyme (also known as restriction endonuclease) is protein which cuts DNA up at specific sequences (called restriction sites) in a genome. For example, the commo

What does a restriction enzyme do?

Restriction enzyme cuts double or single stranded DNA at a specific recognition nucleotide sequences known as restriction site. .

What is the use of restriction enzymes in DNA?

restriction enzymes cut the DNA at specific sites called restriction sites. These restriction sites are 6 - 8 base pairs long and occur at different frequencies on the DNA

Where are restriction enzymes obtained from?

Restriction enzymes are obtained from many prokaryotes and about1500 enzymes with known sequence recognition sites have beenisolated. Restriction enzyme is a protein that reco

What is a topoisomerase?

Topoisomerase: are isomerase enzymes that act on the topology of DNA . Helicase untwists the double helix and separates the template DNA strands at the replication fork..

What function does the enzyme topoisomerase have?

The function of topoisomerase is to unwind the helix of DNA into a regular, ladder-like shape. Topoisomerase is only found in primates. In other organisms, the molecule is cal

What organism uses restriction enzymes?

Bacterias use restriction enzymes as a form of defense mechanism. We as people use these restriction enzymes in bacterias to aid us in genetic engineering.

Enzymatic function of restriction enzymes?

There are actually two types of restriction enzymes, type I and type II. The form commonly referred to as 'restriction enzyme' are type II. These enzymes recognize specific se

How are restriction enzymes used in the laboratory?

Restriction enzymes are used to isolate genes of interest or to insert genes into different genomes (recombination). Essentially, they allow geneticists to modify the genome o

What is the purpose of restriction enzyme?

There main purpose is to cut up viral DNA that invades bacteria. Since they do this at definite sites, depending on which restriction enzyme is used, they can be used in genet
