WebWhy is DNA replicated 5' to 3'? Discussion of the reaction mechanism for DNA (and RNA) synthesis, and why it causes synthesis to proceed only in the 5' to 3' direction. WebNov 24, 2024 · The two strands of a DNA molecule are antiparallel to one another (the backbone of one strand runs from 5'-3' while the complimentary strand runs 3'-5'). Unfortunately, DNA polymerase, the enzyme responsible for replicating DNA, can only make DNA in a 5'-3' direction (and read DNA in the 3'-5' direction). WebJul 1, 2024 · RNA molecules are much shorter than DNA molecules; only a portion of one DNA strand is copied or transcribed to make an RNA molecule.

"WebDNA-polymerase can only work from the 5'-end to the 3'-end. I think in order to understand, just think of the structure of a nucleotide. 1) A nucleotide has a free 5' phosphate end and a free 3' OH end. 2) A strand in 5' to 3' direction indicates a free 5' phosphate at one end and a free 3' OH at the other end.
