Following statements describe the characteristics of the enzyme Restriction Endonuclease. Identify the incorrect statement.Option 1)The enzyme cuts $DNA$ molecule at identified position within the $DNA$.Option 2)The enzyme binds $DNA$ at specific sites and cuts only one of the two strands.Option 3)The enzyme cuts the sugar-phosphate backbone at specific sites on each strand.Option 4)The enzyme recognises a specific palindronic nucleotide sequence in the $DNA$.

S solutionqc

Restriction Endonuclease -

These enzymes cleave DNA only within or near the specific base sequence. These sequences are called as recognition sites. They are of three types RE- I, RE-II and RE-III.

- wherein

1st Restriction enzyme (Hind II) was used in RDT.

Restriction endonuclease bind to the specific sites (palindromic sequences) the $DNA$ and cut both the strands of the $DNA$.

Option 1)

The enzyme cuts $DNA$ molecule at identified position within the $DNA$.

Option 2)

The enzyme binds $DNA$ at specific sites and cuts only one of the two strands.

Option 3)

The enzyme cuts the sugar-phosphate backbone at specific sites on each strand.

Option 4)

The enzyme recognises a specific palindronic nucleotide sequence in the $DNA$.
