Ans 1) Difference - DNA is double stranded where as RNA is single stranded - Four Nitrogenous bases are adenine, thymine, cytosine, and guanine in DNA where as adenine, uracil , guanine, and cytosine in RNA. - DNA is found in nucleus where as RNA is found in cytiplasm Similar Both have phosphate group and 5 carbon sugar. Both are formed from nucleotides Solution Ans 1) Difference - DNA is double stranded where as RNA is single stranded - Four Nitrogenous bases are adenine, thymine, cytosine, and guanine in DNA where as adenine, uracil , guanine, and cytosine in RNA. - DNA is found in nucleus where as RNA is found in cytiplasm Similar Both have phosphate group and 5 carbon sugar.
