Which of the following sequences is recongnised by restriction enzyme BamHI ?

Options

A. `{:(5'-Goverset(darr)A AT T C-3'),(3'-C T T A underset(uarr)AG-5'):}`
B. `{:(5'-Aoverset(darr)A GCTA-3'),(3'-T T CG A underset(uarr)T-5'):}`
C. `{:(5'-Goverset(darr)GAT C C-3'),(3'-C CTAG underset(uarr)G-5'):}`
D. `{:(5'-C C Coverset(darr)A AT-3'),(3'-GGunderset(uarr)GT TA-5'):}`

Answer

C

Explanation

BamHl is obtained from Bacillus amyoliquefaciens H it recongnises a six base pair sequence and produces sticky ends.
`5'-overset(darr)G GATC C -3'`
`3'-C CTAunderset(uarr)G G-5'`
