Population genomics has developed as a popular field of research, where genomic sequencing methods are used to conduct large-scale comparisons of DNA sequences among populations - beyond the limits of genetic markers such as short-range PCR products or microsatellites traditionally used in population genetics. Population genomics studies genome ...
Molecular genetics is a branch of biology that addresses how differences in the structures or expression of DNA molecules manifests as variation among organisms. Molecular genetics often applies an "investigative approach" to determine the structure and/or function of genes in an organism's genome using genetic screens.
Genetics is the study of genes, genetic variation, and heredity in organisms. [ 1 ] [ 2 ] [ 3 ] It is an important branch in biology because heredity is vital to organisms' evolution . Gregor Mendel , a Moravian Augustinian friar working in the 19th century in Brno , was the first to study genetics scientifically.
In comparative genomics, synteny is the preserved order of genes on chromosomes of related species indicating their descent from a common ancestor.Synteny provides a framework in which the conservation of homologous genes and gene order is identified between genomes of different species. [9]
Population genomics is the large-scale comparison of DNA sequences of populations. Population genomics is a neologism that is associated with population genetics . Population genomics studies genome -wide effects to improve our understanding of microevolution so that we may learn the phylogenetic history and demography of a population.
Computational genomics refers to the use of computational and statistical analysis to decipher biology from genome sequences and related data, [1] including both DNA and RNA sequence as well as other "post-genomic" data (i.e., experimental data obtained with technologies that require the genome sequence, such as genomic DNA microarrays).
Neurogenomics: Study of genetic influences on the development and function of the nervous system. Pangenomics: Study of the entire collection of genes or genomes found within a given species. [14] Personal genomics: Branch of genomics concerned with the sequencing and analysis of the genome of an individual. Once the genotypes are known, the ...
A genome is all the genetic information of an organism. [1] It consists of nucleotide sequences of DNA (or RNA in RNA viruses ). The nuclear genome includes protein-coding genes and non-coding genes, other functional regions of the genome such as regulatory sequences (see non-coding DNA ), and often a substantial fraction of junk DNA with no ...
