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 ...
In some cases, the gene letter may be followed by an allele number. All letters and numbers are underlined or italicised. For example, leuA is one of the genes of the leucine biosynthetic pathway, and leuA273 is a particular allele of this gene.
Biology Letters is a peer-reviewed scientific journal published by the Royal Society, established in 2005. It focuses on the rapid publication of short research articles, reviews, and opinion pieces across the biological sciences .
For example, verus is listed without the variants for Aloe vera or Galium verum. The second part of a binomial is often a person's name in the genitive case, ending -i (masculine) or -ae (feminine), such as Kaempfer's tody-tyrant, Hemitriccus kaempferi. The name may be converted into a Latinised form first, giving -ii and -iae instead.

In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder , is sometimes added directly above order, with suborder directly beneath order.
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 ...
For example, early tRNA-like ribozymes may have had different affinities for amino acids, with codons emerging from another part of the ribozyme that exhibited random variability. Once enough peptides were coded for, any major random change in the genetic code would have been lethal; hence it became "frozen".
