Question

Quizplus · Accepted Answer

A splicesome is a complex of proteins and RNA that catalyzes splicing, the process by which introns (non-coding regions) are removed from pre-mRNA and exons (coding regions) are joined together. The splicesomes are made up of small nuclear RNAs (snRNAs) and proteins, and they come together in a highly regulated process to carry out splicing. Holoenzyme refers to an enzyme that contains multiple subunits and/or cofactors. Nucleosome refers to the basic structural unit of chromatin, consisting of DNA wrapped around histone proteins. Ribosome refers to the large macromolecular machine that synthesizes proteins by translating mRNA into amino acid sequences. Chromosome refers to the condensed structure formed by DNA during cell division.
