Transcription: Let's talk about DNA replication. The replication of DNA takes place in the nucleus of the cell. There are a number of players in the replication itself. Among them are the DNA and some specialized enzymes that help the process along. As we mentioned before, the bonds that are formed between the two chains that form the double helix are very weak bonds known as hydrogen bonds. These hydrogen bonds form between the nitro bases. Incidentally, there are three hydrogen bonds between the base pair C and G and two hydrogen bonds between A and T. When it is time for replication to begin, a special en ...
