Question

For the following structural characteristic, decide if it is a characteristic of DNA, a characteristic of RNA, a characteristic of both DNA and RNA, or a characteristic of neither DNA nor RNA.

It is usually a single string of nucleotides.



DNA

RNA

both DNA and RNA

neither DNA nor RNA

Answer 1

The answer is RNA. Only RNA has one single strand, DNA has 2.

Hope this helped :D

Answer 2

RNA

Step-by-step explanation:

RNA presents a single strand (uniqueness), while in DNA, a double strand (complementary duplicity) is observed.

In addition, there are other differences such as molecular weight, nitrogenous bases (both have cytosine, guanine and adenine, but DNA has thymine and RNA has uracil) and the type of sugar present in its molecules, which gave rise to its names: RNA has ribose sugar while DNA has deoxyribose sugar.
