GUANINE NUCLEOTIDE Meaning and
Definition
-
Guanine nucleotide refers to a molecule that is composed of guanine, a nitrogenous base, which is attached to a five-carbon sugar (ribose or deoxyribose) and a phosphate group. This combination forms one unit of a nucleotide, which comprises the building blocks of nucleic acids, including DNA and RNA. Guanine nucleotides are crucial components of these genetic materials and play a fundamental role in various biological processes.
Guanine, one of the four DNA bases, pairs with cytosine through hydrogen bonds in DNA double strands, forming the base pairs that facilitate the double helix structure of DNA. It is also present in RNA, where it pairs with cytosine in a similar manner, contributing to its folding and functioning. The nucleotide form of guanine is essential for the stable and accurate replication, transcription, and translation of genetic information.
Moreover, guanine nucleotides serve as critical signaling molecules involved in numerous cellular processes. They act as carriers of energy in the form of guanosine triphosphate (GTP) and guanosine diphosphate (GDP), participating in various biochemical reactions, including protein synthesis, cell signaling pathways, and regulation of cellular activities. These nucleotides facilitate the transfer of energy and serve as molecular switches that regulate the activity of enzymes and proteins.
In summary, guanine nucleotide is a molecular unit comprised of guanine, a sugar molecule, and a phosphate group, serving as a building block for DNA and RNA. It is involved in genetic coding, replication, and transcription, while also acting as a critical signaling molecule for cellular processes.

Etymology of GUANINE NUCLEOTIDE
The word "guanine" is derived from the word "guano", which refers to the excrement of sea birds and bats. Guano was first discovered and used as a fertilizer in the 19th century. It was later found that guano contained high levels of a nitrogen-containing compound known as guanine, which was isolated and named around the same time.
The term "nucleotide" comes from the Latin word "nucleus", meaning "kernel" or "seed", and the suffix "-ide", which indicates a compound or ion. It was coined by the Swedish chemist Albrecht Kossel in the late 19th century to describe the building blocks of nucleic acids, such as DNA and RNA.
When combined, "guanine nucleotide" refers to a molecule composed of guanine, a nitrogenous base, linked to a sugar molecule and one or more phosphate groups.
