Question

Explain the action of restriction endonucleas Ecoli 1​

Answer 1

Answer:

Explanation:

Restriction endonucleases are enzymes that break the phosphodiester bonds of nucleic acids.

Explanation:

Restriction enzymes recognize and cut at specific sequences.

Some recognize specific groups of 4 bases while many others recognize groups of 6. A 6-base restriction sequence may not exist even once in a given viral DNA molecule.

For example, the

GAATTC

CTTAAG

recognition sequence of the E.coli RI enzyme is not present in the bacteriophage T7 DNA, which is 40,000 base pairs long.
