NEET 2026 Biology question
Which of the following statements are not true regarding restriction endonucleases? A. They are called molecular scissors. B. These are the enzymes responsible for restricting the growth of bacteriophages in *E. coli*. C. They cut the DNA only at the centre of the palindromic sites. D. They remove nucleotides only from the ends of DNA fragments. E. They recognise specific palindromic base-pair sequences. Choose the answer from the options given below :
Solution
A true: restriction enzymes cut DNA and are called molecular scissors. B true: restriction endonucleases were first isolated from *E. coli* as the enzymes restricting bacteriophage growth. C not true: they cut the strands a little away from the centre of the palindromic site (e.g. EcoRI cuts
