DNA structure and protein synthesis
1. Describe the basic structure of a DNA molecule
2. What is meant by the ‘triplet code’?
3. The sequence of DNA bases is described as non-overlapping and
degenerate. Explain what is meant by these terms and why it is
important that DNA has these features.
4. Outline the evidence for the conclusion that the DNA code is nonoverlapping and made of triplet codons.
5. Describe the process of transcription.
6. Explain how DNA influences and controls protein synthesis.
DNA and identification
1. What is DNA profiling? Which regions of DNA are used in this process?
2. What are mini-satellites and micro-satellites in reference to DNA?
3. Outline the technique of electrophoresis to produce a DNA profile.
4. Explain what is meant by ‘southern blotting’.
5. Outline the sequence of events in the Polymerase Chain Reaction.
6. Describe how DNA profiling can be used to identify individuals (criminals
and relatives).
