Web6 jul. 2024 · 2.2) Why does DNA synthesis only proceed in the 5’ to 3’ direction? Because DNA polymerase can only add nucleotides to the 3´ end of the polynucleotide strand. Because the 3´ end of the polynucleotide molecule is more electronegative that the 5´ end. Because that is the direction in which the two strands of DNA unzip. Websynthesized, DNA polymerase then adds DNA to the 3´ end of the RNA. ... synthesis can initiate and continue uninterrupted toward the right end of this strand. Remember: new nucleotides are added in a 5´ 3´ direction, so the template must be copied from its 3´ end. The other strand has a 5´ end at the left with the 3´ end pointing right.

WebExplain why enzymatic DNA synthesis occurs only in the 5’ to 3’ direction. DNA polymerase enzyme helps in the synthesis of DNA molecules from deoxyribonucleotides, the building blocks of DNA.
