WebJoining the nucleotides into a DNA strand. A DNA strand is simply a string of nucleotides joined together. I can show how this happens perfectly well by going back to a simpler diagram and not worrying about the structure of the bases. The phosphate group on one nucleotide links to the 3' carbon atom on the sugar of another one. WebJul 15, 2024 · The answer has to do with hydrogen bonding that connects the bases and stabilizes the DNA molecule. The only pairs that can create hydrogen bonds in that space are adenine with thymine and cytosine with guanine. A and T form two hydrogen bonds while C and G form three. WebMar 5, 2024 · Elongation is the addition of nucleotides to the mRNA strand. RNA polymerase reads the unwound DNA strand and builds the mRNA molecule, using complementary base pairs.
