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.

● ● Illustrate the chromosome changes in interphase and mitosis using a diploid cell that is 2n=4 (two large and two small chromosomes). Label the circles as G1 and G2 stages of interphase and each phase of mitosis (in order). Draw the chromosome in each circle using the following guidelines. 1) For unreplicated chromosome draw a line (/) and for replicated chromosome draw an X. 2) For simplicity, do not indicate that the chromosomes are decondensed chromatin during interphase. 3) Skip drawing the nuclear membrane or spindle fibers, since we are focusing on the chromosomes. Label genes in the resulting daughter cells as A/a and B/b. (These letters represent genes which are at particular places along the DNA molecule. Each chromosomes can have a thousand genes but we are focusing on these two.) Ask me Qs in class if anythign on this is not clear.
