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.
- Which of the following is a structure that is not involved in conjugation in bacteria?
|
A. |
sex pili |
|
|
B. |
mating bridge |
|
|
C. |
conjugative pili |
|
|
D. |
flagellum |
CONJUGATION:- Is the process by which one bacterium transfer genetic material to another through direct contact.During conjugation one bacterium serves as the donor of the genetic material ,and the other serves as the recipient.
