Replication of DNA

Replication of DNA. To be able to explain: the semi-conservative mechanism of DNA replication, including the role of DNA polymerase. How DNA acts as a genetic code by controlling the sequence of amino acids in a polypeptide. That codons for amino acids are triplets of nucleotide bases.

The Structure of DNA

The Structure of DNA. DNA. DNA is often called the blueprint of life . In simple terms, DNA contains the instructions for making proteins within the cell. The Shape of the Molecule. DNA is very long. The basic shape is like a twisted ladder or zipper. This is called a double helix.
