Each restriction enzyme functions by inspecting the length of the $DNA$ sequence.

Vedclass · Answer

(A) Restriction enzymes are endonucleases that recognize specific $DNA$ sequences known as palindromic sequences and cut the $DNA$ at these sites. Option $A$ is incorrect because restriction enzymes do not inspect the length of the $DNA$ sequence; rather,they recognize specific nucleotide sequences (recognition sites) regardless of the total length of the $DNA$ molecule. Option $B$ is correct as they cut at palindromic sites. Option $C$ is correct as they are fundamental tools in genetic engineering. Option $D$ is correct as $DNA$ ligase is used to join the sticky ends produced by restriction enzymes.

$(a)$ Restriction endonuclease	$(i)$ Joins the $DNA$ fragments
$(b)$ Restriction exonuclease	$(ii)$ Extends primers on genomic $DNA$ template
$(c)$ $DNA$ ligase	$(iii)$ Cuts $DNA$ at specific positions
$(d)$ $Taq$ polymerase	$(iv)$ Removes nucleotides from the ends of $DNA$
