How Do You Spell EXORIBONUCLEASES?

Pronunciation: [ɛɡzˈɔːɹɪbˌɒnjuːklˌɪe͡ɪsɪz] (IPA)

Exoribonucleases is a complex scientific term referring to enzymes that digest RNA. The pronunciation of this word is /ɛksɔːraɪbəʊnjuːkleɪzɪz/, which can be broken down as follows: the initial sound is "eks", which means 'out of'; the next syllable "sorai" indicates that the 'o' sounds like the one in 'sore'; the following syllable 'bo' is pronounced with a long 'o'; and finally, 'nu' sounds like 'new', and 'kle' and 'zis' are pronounced like in 'bicycle' and 'sizzle', respectively.

EXORIBONUCLEASES Meaning and Definition

1. Exoribonucleases are a class of enzymes that participate in the degradation and processing of RNA molecules. They are responsible for removing or trimming nucleotides from the ends of RNA molecules, which plays a crucial role in the regulation of gene expression and the maintenance of RNA quality control.

   Exoribonucleases function by catalyzing the hydrolytic cleavage of phosphodiester bonds in RNA molecules, resulting in the release of individual nucleotides or shorter RNA fragments. These enzymes generally work in a 5' to 3' direction, selectively degrading RNA from one end. They can act on either single-stranded or double-stranded RNA and exhibit specificity towards different RNA substrates.

   Exoribonucleases are essential in various cellular processes, including RNA turnover, mRNA decay, RNA surveillance pathways, and the maturation of transfer and ribosomal RNAs. They help in the removal of RNA molecules that are no longer needed or have acquired damage or errors during transcription or processing. Furthermore, exoribonucleases also contribute to the fine-tuning of gene expression levels by affecting the stability and abundance of specific RNA species.

   In summary, exoribonucleases are enzymes involved in the degradation and processing of RNA molecules by selectively removing nucleotides from one end. Their activities are critical for the regulation of gene expression, RNA quality control, and overall RNA homeostasis within cells.

Etymology of EXORIBONUCLEASES

The word "Exoribonucleases" is derived from several components:

1. Exo-: This prefix comes from the Greek word "exō", meaning "out of" or "outside". It is commonly used in scientific terminology to indicate something that acts externally or from the outside.

2. Ribonucleases: This word is a combination of "ribo-" and "-nucleases". "Ribo-" refers to ribonucleic acid (RNA), a molecule that plays a crucial role in protein synthesis. "-Nucleases" is a suffix used to describe enzymes that cleave or break down nucleic acids.

Therefore, when these components are combined, "Exoribonucleases" refers to a group of enzymes that cleave or break down RNA from the outside or externally.
