horizontal gene transfer and how can this process potentially change how we view relatedness among the three Domains? Provide an example of a species with characteristics that results from horizontal gene transfer.
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.
What is horizontal gene transfer and how can this process potentially change how we view relatedness among the three Domains? Provide an example of a species with characteristics that results from horizontal gene transfer.
Gene transfer is the insertion of gene in the form of DNA into cells. There are two ways to transfer the gene-
- Horizontal gene transfer
- Vertical gene transfer
This phenomena occur with the help of bacteriophage.
