Which of the following is correct about restriction enzymes?

Restriction enzymes act as molecular scissors that cut DNA at specific recognition sequences, essential in genetic engineering. This follows from NCERT principle where the relation explains the outcome clearly for students in simple steps.

Which of the following statements about restriction enzymes is correct?

Restriction enzymes recognize palindromic DNA sequences and cut at specific sites. This follows from NCERT principle where the relation explains the outcome clearly for students in simple steps.

Which of the following statement about restriction enzymes is incorrect?

Restriction enzymes do not cut DNA randomly; they recognize specific sequences and cut at precise locations. This follows from NCERT principle where the relation explains the outcome clearly for students in simple steps.

Which of the following statements about restriction enzymes is FALSE?

Some restriction enzymes produce blunt ends instead of sticky ends when cutting DNA. This follows from NCERT principle where the relation explains the outcome clearly for students in simple steps.
