RNA, DNA BASES, RNA BASES

Q. What functions are performed by RNA?

Ans:    RNA serves as carrier of genetic information to site of

protein synthesis. It is essential component of ribosomes and of some enzymes.

Q.        What is structure of DNA?

Ans:    DNA has a double helical structure. Double helixes of

structure are held together by complementary base pairing joined together by hydrogen bonds.

Q. What are structural differences b/w DNA & RNA?

Ans:    (i) DNA contains Adenine, Thymine, Cytosine &

Guanine while RNA has Adenine, Uracil, Cytosine and Guanine.

(ii)       DNA has deoxyribose while RNA has ribose sugars.

(iii)                DNA is doule stranded while RNA is single stranded.
