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 ...
3' untranslated region (3'-UTR). Also three-prime untranslated region, 3' non-translated region (3'-NTR), and trailer sequence.. 3'-end. Also three-prime end.. One of two ends of a single linear strand of DNA or RNA, specifically the end at which the chain of nucleotides terminates at the third carbon atom in the furanose ring of deoxyribose or ribose (i.e. the terminus at which the 3' carbon ...

If the lineages in the phylogenetic tree stand for species, a polytomy shows the simultaneous speciation of three or more species. [6] In particular situations, they may be common, for example when a species that has rapidly expanded its range or is highly panmictic undergoes peripatric speciation in different regions.
Since "triply landlocked" seems not to be a commonly agreed upon term and the sources don't provide a definition by which the claim is true, it seems to me it should be removed. Doctroid 03:13, 22 April 2023 (UTC) Remove it. The concept of being landlocked isn't meaningfully applied to provinces or states within a given country.
Both terms are relative: a derived trait for one clade may be an ancestral trait for a different clade. The term "derived trait" is often used interchangeably with the more technical term apomorphy. descendant developmental biology diploid. Denoted in shorthand with the somatic number 2n.
This glossary of developmental biology is a list of definitions of terms and concepts commonly used in the study of developmental biology and related disciplines in biology, including embryology and reproductive biology, primarily as they pertain to vertebrate animals and particularly to humans and other mammals.
A gyroid is an infinitely connected triply periodic minimal surface discovered by Alan Schoen in 1970. [1] [2] It arises naturally in polymer science and biology, as an interface with high surface area.
