IB Biology DNA Replication and Protein Synthesis HL

The genetic code is always read

• 3 bases at a time in the same direction.

• 4 bases at a time in the same direction.

• 3 bases at a time and the direction varies.

• 4 bases at a time and the direction varies.

DNA replication is called semi-conservative because...

• It has been going on for thousands of years

• Half of the nucleotides are DNA, the other half are RNA
