In a cotransduction experiment using P1, the transfer of one geneis selected for and the presence of the second gene is then determined.If 0 out of 1000 transductants that carry the first gene alsocarry the second gene, what would you conclude about the minimumdistance between the two genes?
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.
In a cotransduction experiment using P1, the transfer of one gene
is selected for and the presence of the second gene is then determined.
If 0 out of 1000 transductants that carry the first gene also
carry the second gene, what would you conclude about the minimum
distance between the two genes?
