Genetic Recombination
Recombination is crucial to this process because it allows genes to be reassorted into diverse combinations. Genetic recombination is the process of combining genetic components from two different origins into a single unit. In prokaryotes, genetic recombination takes place by the unilateral transfer of deoxyribonucleic acid. It includes transduction, transformation, and conjugation. The genetic exchange occurring between homologous deoxyribonucleic acid sequences (DNA) from two different sources is termed general recombination. For this to happen, an identical sequence of the two recombining molecules is required. The process of genetic exchange which occurs in eukaryotes during sexual reproduction such as meiosis is an example of this type of genetic recombination.
Microbial Genetics
Genes are the functional units of heredity. They transfer characteristic information from parents to the offspring.
- What is horizontal gene transfer? What are the three mechanisms for this to occur in bacteria?
- What are the components needed for the processes of transformation, conjugation, and transduction? How does each process occur? What genes are involved in each process?
- How do generalized and specialized transduction differ? What is the end result of each?
- What is recombination? What is the importance to bacteria & archaea?
- What are the two types of recombination? What are the details of each type? What components are needed for each type?
