QUESTION 17 In microbiology, dilutions are critical for getting a countable number of microbes to grow on a petri dish If you suspect your culture of bacteria has 180 x 107 cells per ml, what would you want the final dilution to be in order to end up with 30 colonies of bacteria on a petri dish? Express your answer as an exponent rounded to two decimal places. Eg. 10.01e-3, not 0.00101
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.
