MHT CET Biology question

The recognition sequence of restriction enzyme 'A' is GGCC and that of 'B' is GAATTC. Which statement among the following is true regarding the probable frequency of cutting sites in a genome?

(A)Both A and B cut equality frequently
(B)A cuts once every 676 nucleotides and B cuts 1024 nucleotides
(C)A cuts once every 256 nucleotides and B cuts 4096 nucleotidesCorrect
(D)A cuts once every 256 nucleotides and B cuts 1024 nucleotides

Answer: (C)

Solution

A site of n base pairs occurs about once in nucleotides: GGCC (4 bp) gives = 256 and GAATTC (6 bp) gives
