. In two isolates (one is resistant to ampicillin and theother is sensitive to ampicillin) of a new bacterium,you found that genes encoding ampicillin resistanceare being transferred into the sensitive strain. . To determine if the gene transfer is transformationor transduction, you treat the mixed culture of cellswith DNase. Why would this treatment distinguishbetween these two modes of gene transfer? Describethe results predicted if the gene transfer is transformation versus transduction
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.
