What is the ecor1 cut site?
In molecular biology it is used as a restriction enzyme. EcoRI creates 4 nucleotide sticky ends with 5′ end overhangs of AATT. The nucleic acid recognition sequence where the enzyme cuts is G↓AATTC, which has a palindromic, complementary sequence of CTTAA↓G.
What is a restriction site in DNA?
A restriction site is a sequence of approximately 6–8 base pairs of DNA that binds to a given restriction enzyme. These restriction enzymes, of which there are many, have been isolated from bacteria. Their natural function is to inactivate invading viruses by cleaving the viral DNA.
What is the restriction site of EcoRI enzyme?
Additional Information: The EcoRI is a restriction enzyme that creates four nucleotide sticky ends with the end of 5′. The enzyme cuts at the recognition site of G/AATTC which has a complementary sequence of CTTAA/G.
What is the recognition site for Hind 2?
Hind II recognizes the sequence GTPy/PuAC and generates fragments with blunt ends (1). Compatible ends Hind II generates fragments with blunt ends and is compatible to any other blunt end. Isoschizomers Hind II is an isoschizomer to Hinc II.
What is Gaattc?
GAATTC is a palindromic sequence and can be defined as a sequence of the nucleic acid in a DNA or RNA molecule which is stranded double in which reading is in a firm direction.
What is ecor1 used for?
EcoRI or a similar restriction enzyme is used to cut the gene of interest from the organism. The same restriction enzyme is used to open a bacterial plasmid up for gene insertion. The gene of interest is inserted into the bacterial plasmid via an enzyme called DNA ligase.
What do you mean by restriction site?
Restriction site: A sequence in DNA that can be recognized and cut by a specific restriction enzyme.
How many restriction sites are there in pbr322?
There are six key restriction sites inside the AmpR gene. The circular sequence is numbered such that 0 is the middle of the unique EcoRI site and the count increases through the TetR gene.
Does Hind 3 produce blunt ends?
Option B: Hind 3: It is a type 2 restriction endonuclease which gives sticky ends. It is isolated from Haemophilus influenzae. Eco RV: It is type 2 endonuclease producing blunt ends in the centre of nucleotide sequence GAT/ATC.
What bacteria does HindIII come from?
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.
