Web8 de jan. de 2024 · DNA and RNA are very similar. After all, RNA is supposed to be a copy of DNA. However, there are a few differences between the two molecules. The biggest difference is in their shape: DNA is a two-stranded molecule in the form of a double helix. RNA, on the other hand, is a single-stranded molecule.
WebEach chromosome is formed of DNA and proteins ( basically histamin) . DNA is a double helix; 2 strands, each one has coding areas ( which are 2% and maybe less) and non-coding areas . Within the gene itself there are non-coding sequences which their name is “ introns “. WebA molecule of DNA has two strands, composed of nucleotides, that form a double helix shape. 2.
