Function of restriction enzymes?

They race along strands of DNA and RNA looking for a specific sequence where it cuts and renders that DNA harmless. The most common purpose is for security. If a foreign molec

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 is the role of restriction enzymes in bacteria?

Restriction enzyme in bacteria cuts of the foreign DNA inside the host, thus destroying them. The host DNA is protected against this destructive action due to methylation of t

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 can restriction enzymes leave?

Restriction enzymes can leave blunt or sticky ends. This will depend on where they cut the DNA, if they cut at the same point on both strands, they will leave a blunt end, if

Why did restriction enzymes evolve?

They are the bacteria's immune system designed to cut up and destroy invading bacteriophage ( Viruses that attack specific bacteria)They recognize specific sequences of DNA fo

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 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
