A strain of Neisseria gonorrheae has recently acquired the ability to be resistant to the antibiotic penicillin. Evidence indicates that this is not a new mutation but rather a gene received from another bacterium. After the new genetic information recombines with the genome, how would gonorrheae use the DNA to resist the action of penicillin? The gene would be transcribed into RNA and then translated into protein. The gene would translated into protein and then transcribed into RNA. The gene would be recognized as a mutation and repaired. The gene would be released from the N. gonorrheae as naked DNA.
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.
