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 are the diffrences between bacteria and archea?
Archaea were categorized as bacteria initially, but biochemical studies found that they have striking dissimilarities. Archaea and bacteria are similar in the way that they both are prokaryotes and do not have a definite nucleus and cell organelles. Their cellular material is distributed unevenly within the cell.
The major differences between archaea and bacteria is that
- Archaea are the unicellular organisms that are not seen in many shapes but bacteria on the other hand have characteristic shapes like rod shaped, spherical shaped and spiral shaped bacteria.
- The cell wall of the bacteria is composed of peptidoglycan or lipopolysaccharide while that of an archaea is composed of pseudopeptidoglycan.
- Generally archaea love to inhabit in extreme environments like hot springs, near volcanoes, gut of human beings and other ruminants. Bacteria on the other hand, are more diversely populated everywhere. They can be found in soil, water, animals, plants etc.
