Wie DNA verdoppelt wird: Einfache Animationen

DNA polymerase moves along the template strand, adding new nucleotides to create the complementary strand.The enzyme selects nucleotides from the surrounding pool of building blocks.Base pairing follows strict rules: Adenine pairs with Thymine, and Guanin pairs with Cytosine.Finally, the enzyme connects the sugar-phosphate backbone of the new strand.As DNA replication nears completion, we can see two new DNA molecules forming.This process follows the semi-conservative model, where each new DNA molecule contains one original strand and one newly synthesized strand.Special proofreading enzymes carefully check the newly synthesized DNA strands for any errors.If an error is found, the enzyme immediately corrects it to ensure perfect replication.After error checking is complete, the two new DNA molecules separate fully. Each is an exact copy of the original DNA.Each new DNA molecule contains one original strand shown in dark blue, and one new strand shown in light blue.
