Web19 apr. 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. WebDuring transcription, the RNA polymerase after the initial abortive attempts traverses the template strand of DNA in 3’ to 5’ direction, producing a complementary RNA strand in 5’ to 3’ direction.
