The base that rna has but dna doesn’t
WebDuring transcription, enzymes called RNA polymerases build RNA molecules that are complementary to a portion of one strand of the DNA double helix (Figure 3). RNA molecules differ from DNA ... WebApr 19, 2024 · While DNA is double-stranded, forming a double helix shape, RNA is single-stranded, and its chains are significantly shorter than DNA chains (a few thousand base pairs at most, compared to millions of DNA base pairs). RNA’s single-strand structure allows it to form complex three-dimensional shapes.

WebBasic Structure of RNA. The basic structure of RNA is shown in the figure below-The ribonucleic acid has all the components same to that of the DNA with only 2 main differences within it. RNA has the same nitrogen bases called the adenine, Guanine, Cytosine as that of the DNA except for the Thymine which is replaced by the uracil.
WebRNA Primase: Adds RNA primers. Helicase: unzips/unwinds the DNA helix by breaking the bonds between the bases.
