Question

Which of the following is/are difference(s) between DNA and RNA?

• A. DNA is double stranded while RNA is single stranded.
• B. DNA has thymine while RNA has uracil
• C. DNA has deoxyribose sugar and RNA has ribose sugar
• D. DNA has phosphate ion and RNA has magnesium ion

Answer 1

Answer: (A), (B), (C)

The correct options are
A DNA is double stranded while RNA is single stranded.
B DNA has thymine while RNA has uracil
C DNA has deoxyribose sugar and RNA has ribose sugar

Following are the differences between DNA and RNA:

i) DNA is double stranded while RNA is single stranded.

ii) DNA has thymine and RNA has uracil as a nitrogenous base.

iii) DNA has deoxyribose sugar and RNA has ribose sugar.

Both the nucleic acids contain phosphate ion.
