RNA DNA

The video explains the two types of nucleic acids, DNA and RNA, detailing their structures, components, and functions. DNA is a double-stranded molecule with a double helix shape, containing the bases adenine, thymine, cytosine, and guanine. RNA is single-stranded and includes adenine, uracil, cytosine, and guanine. The video covers nucleotide structure, base pairing rules, and the roles of DNA and RNA in protein synthesis. It also introduces the three types of RNA: messenger RNA, ribosomal RNA, and transfer RNA.
