Question

Using the following words, explain the difference between

DNA and RNA.

Nucleus, uracil, double helix

Answer 1

DNA has four nitrogen bases, one of them being thymine. For RNA, instead of having thymine, it has uracil. DNA is a double stranded (also known as double helix) and RNA is single stranded. This explains why RNA can leave the nucleus and DNA can’t.

Answer 2

RNA is single-stranded while DNA is double-stranded.
RNA contains uracil while DNA contains thymine.
RNA has the sugar ribose while DNA has the sugar deoxyribose.
