Purines, Pyrimidines and Nucleic Acid Metabolism

Question
8 out of 14
 

The breakdown product of ribonuclease action is



A Nucleoside 5’ phosphate

B Nucleoside 3’ phosphates only

C Nucleoside 3’ phosphate + oligo nucleotides

D Purine & pyrimidine bases

Ans. C nucleoside 3’ phosphate + oligonucleotides

a. Specific Nucleases digest nucleic acids. Both deoxyribonuclease and ribonuclease — capable of cleaving internal phosphodiester bonds to produce either 3’ -hydroxyl and 5’ -phosphoryl terminal or 5’ -hydroxyl and 3’ -phosphoryl terminals.

b. These are referred to endonucleases

i. Ribonuclease Acts on Ribonucleic acids, and end product are Nucleotides

ii. Deoxyribonuclease acts on Deoxyribonucleic acid and end products are Nucleotides
