Question

After binding to the two strands of the double helix DNA, where specifically does the restriction enzyme act to cut the two strands of DNA? Write the specific term used for the specific nucleotide sequences of DNA recognised by a restriction endonuclease.

Hint:

Recognition sequences in DNA are palindromic, enabling restriction enzymes to bind and cut at precise locations.

Answer 1

Restriction enzymes act at specific recognition sites or sequences on the double-stranded DNA. These sites are typically palindromic sequences, where the enzyme cuts the DNA to generate sticky or blunt ends. The specific term used for the nucleotide sequences recognised by a restriction endonuclease is recognition sequence.
