BIOLOGY 151 Study Guide - Midterm Guide: Missense Mutation, Signal Recognition Particle, Silent Mutation
Document Summary
Hallmarks of cancer failure to respond to growth controls: self sufficiency for growth signals. 2: sustained angiogenesis, evasion of programmed cell death. 6: genomic instability/high mutation rate, metabolic changes-cachexia limitless replicative materials tissue invasion and metastasis. Multiple transcription factors are required for gene expression. Transcription factors activate or block gene expression in specific combinations. Dna sequences and the presence or absence of specific transcription factors determined gene expression. acidic amino acids have a negative charge basic amino acids have a positive charge. There is polar and non polar amino acids are held together by peptide bonds. Aug is met and it is the only start codon the three stop codons are uag, uga, ugg. Rna interference: cut up messenger rna and prevents it from working mirna sirna. Read dna replication sections nuclear localization sequence: is an amino acid sequence which "tags" a protein for import into the cell nucleus by nuclear transport.
