Question:

The correct statement regarding RNA and DNA respectively is:

the sugar component in RNA is arabinose and the sugar component in DNA is2′−deoxyribose

the sugar component in RNA is2′−deoxyriboseand the sugar component in DNA is arabinose

the sugar component in RNA is ribose and the sugar component in DNA is2′−deoxyribose

the sugar component in RNA is arabinose and the sugar component in DNA is ribose

Solution:

The sugar component in RNA is ribose and the sugar component in DNA is 2'-deoxyribose. RNA is ribose nucleic acid and DNA is 2'-deoxyribose nucleic acid.
