Various strains of bacteria are able to transfer genes to eukaryotic hosts. This process of horizontal gene transfer often results in the formation of enzymes in the host organism that assist in metabolic pathways. Which of the following is the most likely explanation for why bacterial genes are able to successfully transfer genes that produce enzymes in eukaryotic cells? A - Bacteria and Eukarya have similar mechanisms for the formation and use of enzymes in metabolic processes. B - Bacteria and Eukarya use the same enzymes in all of their metabolic processes so the genes are interchangeable. C - Bacteria and Eukarya share similar reproductive mechanisms so the cells reproduce without recognizing foreign DNA. D - Bacteria and Eukarya have the same mechanism for replicating DNA so genes can easily be transferred between the two types of cells.
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.
