|
Restriction Enzymes can cut at any sequence of DNA
|
|
True
|
|
|
False
|
|
|
Either A or B
|
|
|
None of the above
|
Explanation:
Detailed explanation-1: -Restriction enzymes have a very specific sequence at which they can cleave DNA. They never cleave the DNA at random sites.
Detailed explanation-2: -In the laboratory, restriction enzymes (or restriction endonucleases) are used to cut DNA into smaller fragments. The cuts are always made at specific nucleotide sequences. Different restriction enzymes recognise and cut different DNA sequences.
Detailed explanation-3: -So, the correct option is ‘They are made by bacteria and viruses’.
