Answer 1

Answer:

(a) is right answer ..... hope help

Answer 2

Elements that are required for DNA and RNA synthesis are carbon, nitrogen, and phosphorous. (option c)

• DNA and RNA are deoxyribonucleic acids and ribonucleic acids respectively.
• They have a ribose sugar (for RNA) or deoxyribose sugar (for DNA) ring, which consists of carbon, hydrogen, and oxygen.
• A nitrogenous base is attached with a sugar ring.
• Also, there is a phospho-di-ester linkage that gives DNA and RNA directionality of 5' and 3'.
• All these 3 make up a nucleotide.
• Thus option c is correct.
