[4] Halobacterium salinarum and Haloferax volcanii, model Haloarchaea. The former has a reputation in the study of DNA repair. The latter is more suited to more traditional genetics due to a shorter generation time and more stable genome. This order is known for its easy updake of genetic tools as well as resistance to culture contamination. [4]
The total number of genetic traits or characteristics in the genetic make-up of a population, species, or other group of organisms. It is often used as a measure of the adaptability of a group to changing environments. Genetic diversity is similar to, though distinct from, genetic variability. genetic drift
Horizontal gene transfer (HGT) or lateral gene transfer (LGT) [1] [2] [3] is the movement of genetic material between organisms other than by the ("vertical") transmission of DNA from parent to offspring (reproduction). [4] HGT is an important factor in the evolution of many organisms.
The transmission of genes to an organism's offspring, is the basis of the inheritance of phenotypic traits from one generation to the next. These genes make up different DNA sequences, together called a genotype, that is specific to every given individual, within the gene pool of the population of a given species.
The genetic process of mutation takes place within an individual, resulting in heritable changes to the genetic material. This process is often characterized by a description of the starting and ending states, or the kind of change that has happened at the level of DNA (e.g,. a T-to-C mutation, a 1-bp deletion), of genes or proteins (e.g., a ...
Based on a phylogenetic analysis, Dacks and Roger have proposed that facultative sex was present in the group's common ancestor. [51] A core set of genes that function in meiosis is present in both Trichomonas vaginalis and Giardia intestinalis, two organisms previously thought to be asexual.
Molecular phylogenetics (/ m ə ˈ l ɛ k j ʊ l ər ˌ f aɪ l oʊ dʒ ə ˈ n ɛ t ɪ k s, m ɒ-, m oʊ-/ [1] [2]) is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine ...
Clinical metagenomic sequencing shows promise as a sensitive and rapid method to diagnose infection by comparing genetic material found in a patient's sample to databases of all known microscopic human pathogens and thousands of other bacterial, viral, fungal, and parasitic organisms and databases on antimicrobial resistances gene sequences ...
