Gene nomenclature is the scientific naming of genes, the units of heredity in living organisms. It is also closely associated with protein nomenclature, as genes and the proteins they code for usually have similar nomenclature. An international committee published recommendations for genetic symbols and nomenclature in 1957. [ 1 ]
Used in a variety of ways, often to indicate well-preserved specimens, well-developed bones, "truer" examples of fossil forms, or simply admiration on the part of the discoverer. Examples: Euparkeria ("good one of Parker's"); Euhelopus ("good marsh foot"); Eustreptospondylus ("well-curved vertebrae"); Eucoelophysis ("truly hollow form")
Amniocentesisis a medical procedure used primarily in the prenatal diagnosisof genetic conditions.[1] It has other uses such as in the assessment of infection and fetal lung maturity.[2] Prenatal diagnostic testing, which includes amniocentesis, is necessary to conclusively diagnose the majority of genetic disorders, with amniocentesis being ...
Suffix. In linguistics, a suffix is an affix which is placed after the stem of a word. Common examples are case endings, which indicate the grammatical case of nouns and adjectives, and verb endings, which form the conjugation of verbs. Suffixes can carry grammatical information (inflectional endings) or lexical information (derivational ...
A gene family is a set of several similar genes, formed by duplication of a single original gene, and generally with similar biochemical functions. One such family are the genes for human hemoglobin subunits; the ten genes are in two clusters on different chromosomes, called the α-globin and β-globin loci. These two gene clusters are thought ...
Gene structure is the organisation of specialised sequence elements within a gene. Genes contain most of the information necessary for living cells to survive and reproduce. [ 1 ][ 2 ] In most organisms, genes are made of DNA, where the particular DNA sequence determines the function of the gene. A gene is transcribed (copied) from DNA into RNA ...
The molecular gene is a sequence of nucleotides in DNA that is transcribed to produce a functional RNA. There are two types of molecular genes: protein-coding genes and non-coding genes. [ 1 ][ 2 ][ 3 ] During gene expression (the synthesis of RNA or protein from a gene), DNA is first copied into RNA.
