Intrauterine growth restriction (IUGR), or fetal growth restriction, is the poor growth of a fetus while in the womb during pregnancy. IUGR is defined by clinical features of malnutrition and evidence of reduced growth regardless of an infant's birth weight percentile. [ 5 ]
If small for gestational age babies have been the subject of intrauterine growth restriction, formerly known as intrauterine growth retardation, [5] the term "SGA associated with intrauterine growth restriction" is used. Intrauterine growth restriction refers to a condition in which a fetus is unable to achieve its genetically determined ...
Pseudogenes are usually characterized by a combination of similarity or homology to a known gene, together with a loss of some functionality. That is, although every pseudogene has a DNA sequence that is similar to some functional gene, they are usually unable to produce functional final protein products. [1]
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
When a family or genus goes extinct it must be true extinction, because pseudoextinction would mean that at least one member of the family or genus is still extant. [ 13 ] Pseudoextinction is an event that occurs much more frequently under the assumption of a Phyletic gradualism model of evolution, under which speciation is slow, uniform and ...
pseudo dicentric – only one centromere in a dicentric chromosome is active q: Long arm of a chromosome r: Ring chromosome t: Translocation: ter: Terminal end of arm (e.g. 2qter refers to the end of the long arm of chromosome 2) tri: Trisomy: trp: Triplication of a portion of a chromosome
Several important biological processes rely on RNA molecules that form pseudoknots, which are often RNAs with extensive tertiary structure.For example, the pseudoknot region of RNase P is one of the most conserved elements in all of evolution.
Pseudopseudohypoparathyroidism (PPHP) is an inherited disorder, [1] named for its similarity to pseudohypoparathyroidism in presentation. It is more properly Albright hereditary osteodystrophy, although without resistance of parathyroid hormone (PTH), as frequently seen in that affliction.
