How Do You Spell NUCLEOSIDES?

Pronunciation: [njˈuːklɪˌɒsa͡ɪdz] (IPA)

Nucleosides are organic molecules that serve as building blocks of nucleic acids. The correct spelling of the word can be explained with the IPA phonetic transcription as /ˌnjuːkliəˈsaɪdz/. The first syllable "nu-" is pronounced as [nu:], followed by the stressed syllable "-cle-" pronounced as [kli:]. The word ends with "-o-" pronounced as [əʊ] and "-sides" pronounced as [saɪdz]. The correct spelling and pronunciation of nucleosides are crucial in scientific research and medical field for accurate communication and understanding of nucleic acid structures and functions.

NUCLEOSIDES Meaning and Definition

1. Nucleosides are organic compounds that serve as the basic building blocks of nucleic acids, which are the essential molecules involved in storing and transmitting genetic information in living organisms. The structure of a nucleoside consists of a five-carbon sugar molecule, known as a pentose, bonded to a nitrogen-containing base. The base may be either a pyrimidine, such as cytosine, uracil, or thymine, or a purine, such as adenine or guanine.

   The pentose sugar in a nucleoside is typically either ribose or deoxyribose, with the latter lacking an oxygen atom when compared to ribose. This distinction determines whether the resulting nucleoside contributes to the formation of RNA (ribonucleic acid) or DNA (deoxyribonucleic acid), respectively.

   Although nucleosides do not contain a phosphate group like nucleotides, they play a crucial role in the synthesis of nucleic acids. When nucleosides undergo phosphorylation, involving the addition of a phosphate group, they are transformed into nucleotides. Nucleotides are the monomers that link together to form the polynucleotide chains of DNA or RNA. The phosphate group is responsible for the formation of the backbone of these chains and also plays a role in energy transfer within a cell.

   In addition to their role as building blocks of genetic material, nucleosides have also been identified as components in several coenzymes, such as ATP (adenosine triphosphate) and NAD+ (nicotinamide adenine dinucleotide). These coenzymes participate in vital cellular processes, including energy metabolism and enzymatic reactions.

Etymology of NUCLEOSIDES

The word "nucleoside" is derived from the combination of two words: "nucleo-" and "-side".

1. "Nucleo-" is derived from the Latin word "nucleus", which means "kernel" or "core". In this context, it refers to the central part of a cell or an atom.

2. "-Side" is a suffix that originated from the Latin word "sīdus", meaning "star". "-Side" is commonly used in chemistry to denote a substance derived from another substance, often with a similar structure, but through a specific modification or substitution.
