Genome:

Chromosome:

Gene:  

Genetic code:

Genotype:

Phenotype:

Genomics:

2. Describe the process of DNA replication.

 

3. Describe protein synthesis:
4. Explain the regulation of gene expression in bacteria by operon, induction, repression, and catabolic repression.

5. Classify mutations by type, and describe how mutations are prevented and repaired. Mutation:

 

6. Define mutagen:
7. Describe two ways mutations can be repaired.

Spontaneous mutation rate = 1 in 10⁹ replicated base pairs or 1 in 10⁶ replicated genes

Mutagens increase to 10^–5 or 10^–3 per replicated gene

8. Compare the mechanisms of genetic recombination in bacteria. Recombination:
9. Differentiate between horizontal and vertical gene transfer.

 

10. ---Describe the functions of plasmids and transposons.

 

11. Discuss how genetic mutation and recombination provide material for natural selection to act on.
