BIOL 120 Lecture 7: BMSC 220.3 Notes for Topic 7
Document Summary
Bmsc 220. 3 cell biology. Topic 7: protein synthesis and processing. Regulation of protein levels in the cell and protein degradation ). Fall 2015: controlled polyadenylation of mrna is also an important mechanism for the regulation of translation during early development. In addition, the general translation activity of cells can be regulated by modification of initiation factors. Regulation of protein function: regulation by small molecules: The nuclear envelope & traffic between the nucleus and the cytoplasm. Sub- compartments within the nucleus: many nuclear processes are localized to discrete sub- nuclear structures. 18s, 5. 8s, and 28s rrnas. Rnas, including trnas, snrnas and signal recognition particle rna. Topic 7, part 1 lecture slides. Initiation factors: added layers of regulation and control. Objective 1: review the general means by which a mrna sequence is translated to a protein. Translation: remember to clearly differentiate the terms transcription and translation. The language is codons, triplets that code for amino acids. Nucleotides amino acids.
