BIOB11H3 Study Guide - Midterm Guide: Satellite Dna, Minisatellite, Telomere
Document Summary
Bio b11 comprehensive: explain fluorescent in situ hybridization. Increases with increasing distance from the point of initiation. Original rna synthesized from template dna (transcription unit) To be transcribed and non-coding to allow for variability in alternative splicing. Short half-life (in minutes) so it is rapidly degraded/turned over. A large percent of rna being synthesized by the cell at any time is hnrna or rna. To be used for synthesized from one dna molecule. Template for translation smaller rna molecules and exported to cytoplasm into a polypeptide by ribosomes in the cytoplasm rrna. Pol i (synthesized in nucleolus) in cells is rrna. Iii (not synthesized in reaction which amino acids are covalently linked together nucleolus) There are multiple copies of genes encoding rrna, so it has moderately repeated. Encoded by repeated dna sequences (tdna) in small clusters scattered around the genome in a tandem repeated array. Has an internal promoter, so it is transcribed by rna.
