I can help! My name is DNA Ligase, and I can join the Okazaki fragments together.
Thank you very much!
Now we have two strands of the identical DNA! We successfully replicated the DNA!
Great job guys! Now we have to repeat everything we just did starting at each replication origin. I know it seems like a lot of work, but we can do it if we all work together!
I wish we had done Prokaryotic DNA Replication instead of Eukaryotic DNA Replication, so there would only be one replication origin and we would be done already.
DNA is made up of nucleotides, and each nucleotide has a phosphate group, which is covalently bonded to a deoxyribose sugar, which is covalently bonded one of four nitrogen bases - adenine, thymine, guanine, or cytosine. These bases are connected to another base from another nucleotide with a hydrogen bond, and I am breaking these hydrogen bonds to unwind the DNA.
