PY - 2014 T2 - Integrative Medical Biochemistry Examination and Board Review AB - High-Yield TermsTranscription: describes the process by which the genetic information in a gene is converted into polyribonucleotides, the RNAsPromoter: sequences in the gene that promote the ability of RNA polymerases to recognize the nucleotide at which initiation begins; must reside close to the gene and in a specific orientation for activityEnhancer: sequences that act in cis by binding proteins that result in enhancement of transcription; can be located long distance from the gene or even on different chromosomes, also do not require orientation for activitySplicing: the process whereby the introns are removed from heteronuclear RNA (hnRNA)RNA editing: a novel enzymatic mechanism for the modification of nucleotide sequences of RNA, resulting in altered coding capacitySmall noncoding RNAs: includes the U small nuclear RNAs (snRNAs) of the splicing machinery, the microRNAs (miRNAs) derived from noncoding genes that are involved in processes of expression control, and the small interfering RNAs (siRNAs) responsible for the process of RNA-mediated interference (RNAi) in gene expressionribozyme: an enzyme activity solely associated with an RNA molecule, such as the peptidyltransferase activity of the large ribosomal subunit SN - PB - McGraw-Hill Education CY - New York, NY Y2 - 2024/03/29 UR - accesspharmacy.mhmedical.com/content.aspx?aid=1122104765 ER -
