Ch 12 DNA Replication

In this short unit, we will be studying the DNA molecule in detail. We will look at the specific structure of the subunits (nucleotides) as well as the structure of the DNA molecule itself.

We will also study the process where DNA is replicated, paying special attention to the enzymes which aid in replication.

All of this is in preparation and to contrast to the next unit, RNA and Protein Synthesis, where we learn how the nucleus runs the operations of the cell.

Pages in the book to read: 12.1 - 12.3, 338– 353
