Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Another name for restriction enzymes is
A
Taq polymerase
B
Restriction endonuclease
C
Restriction sites
D
DNA helicase
Explanation: 

Detailed explanation-1: -Restriction enzymes are also called “molecular scissors” as they cleave DNA at or near specific recognition sequences known as restriction sites. These enzymes make one incision on each of the two strands of DNA and are also called restriction endonucleases.

Detailed explanation-2: -Restriction enzymes, also called restriction endonucleases, recognize a specific sequence of nucleotides in double stranded DNA and cut the DNA at a specific location.

Detailed explanation-3: -restriction enzyme, also called restriction endonuclease, a protein produced by bacteria that cleaves DNA at specific sites along the molecule. In the bacterial cell, restriction enzymes cleave foreign DNA, thus eliminating infecting organisms.

Detailed explanation-4: -Restriction endonuclease: An enzyme from bacteria that can recognize specific base sequences in DNA and cut (restrict) the DNA at that site (the restriction site). Also called a restriction enzyme.

Detailed explanation-5: -In molecular biology, endonucleases are enzymes that cleave the phosphodiester bond within a polynucleotide chain (namely DNA or RNA).
