A couple of questions

Is Type III an endonuclease?

Type III restriction enzymes are a group of endonucleases that recognize a non-pallindromic sequence, comprising two inversely oriented sites.

What are types of endonucleases?

There are three categories of restriction endonucleases: Type I, Type II and Type III. They are categorized based on their mechanism of action. They are regularly used in genetic engineering to create recombinant DNA, which can be introduced into different cells of bacterial, plant or animal origin.

What type of enzyme is endonuclease?

Restriction endonucleases (REs) are bacterial enzymes that cleave double-stranded DNA. Type I REs are important in bacterial function but do not cleave DNA at specific sequences.

What is an example of an endonuclease?

Some examples of type II restriction endonucleases include BamHI, EcoRI, EcoRV, HindIII, and HaeIII. Type III, however, cleaves the DNA at about 25 base pairs from the recognition sequence and also requires ATP in the process.

Is Hind III a restriction endonuclease?

HindIII (pronounced "Hin D Three") is a type II site-specific deoxyribonuclease restriction enzyme isolated from Haemophilus influenzae that cleaves the DNA palindromic sequence AAGCTT in the presence of the cofactor Mg2+ via hydrolysis. …

What is Type 3 restriction endonuclease?

Type III restriction enzymes are a group of endonucleases that recognize a non-pallindromic sequence, comprising two inversely oriented sites.

What is RNA endonuclease?

The RNA-splicing endonuclease is an evolutionarily conserved enzyme responsible for the excision of introns from nuclear transfer RNA (tRNA) and all archaeal RNAs.

Which of the following is not an endonuclease?

Which of the following is NOT an endonuclease? Explanation: Endonuclease are those which break internal phosphodiester bonds of DNA while exonuclease removes nucleotide from the end of the DNA. Examples: mung bean nuclease, S1 nuclease, Rnase A, and RNase H.
