RIBONUCLEOTIDES Meaning and
Definition
-
Ribonucleotides are small molecules that serve as the building blocks of RNA (ribonucleic acid) during its synthesis within a living organism. They are composed of three main components: a nitrogenous base, a five-carbon sugar molecule (ribose), and a phosphate group. The nitrogenous base can be one of four types: adenine (A), guanine (G), cytosine (C), or uracil (U).
Ribonucleotides are important for cellular processes such as gene expression, protein synthesis, and the transmission of genetic information. They are synthesized in the cell through a series of enzymatic reactions. These reactions involve the addition of phosphate groups to the ribose sugar, followed by the attachment of a specific nitrogenous base. The resulting ribonucleotide molecules can then join together through phosphodiester bonds to form RNA chains.
In living organisms, ribonucleotide triphosphates (RTPs) are the most common form of ribonucleotides. They possess three phosphate groups in their structure. During RNA synthesis, one or two of these phosphate groups are cleaved off, releasing energy that is utilized in the formation of phosphodiester bonds. This process allows the ribonucleotides to link in a specific sequence, dictated by complementary base pairing, to form RNA molecules with diverse functions.
Overall, ribonucleotides are essential components in the structure and function of RNA, playing a crucial role in various biological processes within living organisms.

Etymology of RIBONUCLEOTIDES
The word "ribonucleotides" is derived from a combination of three components: "ribo-", "nucleo-", and "-tides".
1. "Ribo-" comes from the term "ribose", which refers to a type of sugar. Ribose is a fundamental component of RNA (ribonucleic acid). The prefix "ribo-" indicates the presence of ribose in the nucleotide.
2. "Nucleo-" is derived from the term "nucleotide", which is the building block of nucleic acids. Nucleotides consist of a nucleobase (a nitrogenous base), a ribose sugar, and a phosphate group, forming the basic structural unit of DNA and RNA.
3. "-Tides" is a suffix often added to the end of words to denote a connection with nucleotides.
