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. WebExpert Answer. 1. A 3' to 5', 5' to 3' The main function of the DNA polymerase is to produce a copy of DNA from the deoxyribonucleotides. The directionality of the newly forming strand (the daughter strand) is opposite to the direction in which DNA …
