In biology and medicine, gravidity and parity are the number of times a female has been pregnant (gravidity) and carried the pregnancies to a viable gestational age (parity). [1] These two terms are usually coupled, sometimes with additional terms, to indicate more details of the female's obstetric history. [2] When using these terms:
Guanosine-5'-triphosphate (GTP) is a purine nucleoside triphosphate.It is one of the building blocks needed for the synthesis of RNA during the transcription process. Its structure is similar to that of the guanosine nucleoside, the only difference being that nucleotides like GTP have phosphates on their ribose sugar.
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 ...
Guanosine diphosphate, abbreviated GDP, is a nucleoside diphosphate.It is an ester of pyrophosphoric acid with the nucleoside guanosine.GDP consists of a pyrophosphate group, a pentose sugar ribose, and the nucleobase guanine.
Meaning: a prefix used to make words with a sense opposite to that of the root word; in this case, meaning "without" or "-less". This is usually used to describe organisms without a certain characteristic, as well as organisms in which that characteristic may not be immediately obvious.
CpG is shorthand for 5'—C—phosphate—G—3' , that is, cytosine and guanine separated by only one phosphate group; phosphate links any two nucleosides together in DNA. . The CpG notation is used to distinguish this single-stranded linear sequence from the CG base-pairing of cytosine and guanine for double-stranded sequenc
A nucleoside triphosphate is a nucleoside containing a nitrogenous base bound to a 5-carbon sugar (either ribose or deoxyribose), with three phosphate groups bound to the sugar. [1]
Schematic of GEF activation of a GTPase. Guanine nucleotide exchange factors (GEFs) are proteins or protein domains involved in the activation of small GTPases.Small GTPases act as molecular switches in intracellular signaling pathways and have many downstream targets.
