Which of the following enzyme is used in DNA multiplication?
1 DNA polymerase
2 RNA polymerase
3 DNA endonuclease
4 Exonuclease
Explanation:
DNA polymerase enzyme is used in DNA multiplication. DNA polymerases are enzymes that create DNA molecules by assembling nucleotide, the building block of DNA. - RNA polymerase :- RNA polymerase is an enzyme that is responsible for copying a DNA sequence into an RNA sequence, during the process of transcription.

Histone proteins are positively charged because they are rich in basic amino acid residues
1 Arginine and Proline
2 Arginine and Alanine
3 Arginine and Lysine
4 Arginine and Phenylalanine
Explanation:
Histone is positively charged, basic protein. Histon protein acquires charge depending upon the abundance of amino acids residue with charged side chain. Histone are rich in the basic amino acid residues lysines and arginies. Both the amino acid residues carry positive charge in their side chain histon are organised to form a unit of eight molecules called as histone octamer.

Arrange the three steps of PCR each cycle in sequence I. Denaturation II. Extension of primers III. Primer annealing IV. DNA Ligation
1 I, III and II
2 II, III and IV
3 I, II and III
4 IV, III and I
Explanation:
PCR stands for polymerase chain Reaction. In this reaction, multiple copies of the gene of interest is synthesised in uitro using two sets of primers and the enzyme DNA polymerase. In polymerase chain reaction each cycle has three steps- I. Denaturation II. Extension of primers III. Primer annealing
