WebLike DNA, RNA is made up of nucleotide consisting of a 5-carbon sugar ribose, a phosphate group, and a nitrogenous base. However, there are three main differences between DNA and RNA: RNA uses the sugar ribose instead of deoxyribose. RNA is generally single-stranded instead of double-stranded. RNA contains uracil in place of thymine. WebtRNA, like mRNA is formed by transcription. this is where DNA polymerase 3 transcribes dna to RNA.
