State true or false:
Exonucleases remove nucleotides at specific positions within DNA.

Exonucleases remove nucleotides from

Assertion: Exonucleases remove nucleotides from the ends of DNA. Reason: Endonucleases make cuts at specific positions within the DNA.

Consider the following statements. A. Endonucleases remove nucleotides from the ends of the DNA whereas, exonucleases make cuts a specific positions within the DNA. Restriction enzymes cut the strand of DNA a little away from the centre of the palindrome sites. C. Asexual reproductions provides opportunities for variations and formulation of unique combinations of genetic setup. ltbrtgt D. DNA fragments can be separated by a technique known as gel electrophoresis. Of the above statements:

Read the following statements and select the correct ones. (i) Same kind of sticky ends are produced when a DNA has been cut by different restriction enzymes. (iii) Exonucleases make cuts at specific positions within the DNA. (iii) Hind ll was the first restriction endonuclease to be isolated. (iv) A bacteriophage has the ability to replicate within bacterial cells by integrating its DNA with bacterial DNA. (v) Presence of more than one recognition sites for a enzyme within the vector complicates the gene cloning.

State true (T) or false (F).

Which nuclease remove nucleotides from the ends of the DNA ?

A specific recognition sequence identified by endonuclease to make cut at specific positions within the DNA is

Assertion (A) : Restriction enzymes belongs to class nucleases. Reason (R) : Nucleases are of two kinds : exo and endonucleases. Exonucleases remove nucleotides within the DNA.
