91132 Study Guide - Final Guide: Alternative Splicing, Tata Box, Start Codon
Document Summary
The consequence of this mutation would be a change in the codons downstream from the mutation. They are very soluble in water because they contain sugars and phosphates on the outside. Human have an estimated 21000 protein coding gene. Messenger rna: single stranded, pre-mrna produced first. Alternative splicing encode more than one peptide via different combination of extrons or introns trna: recognise the sequence, translate proteins, 80 nucleotide long. The synthesis of rna as directed by dna the mrna sequence. Specific dna sequences delineate initiation site and termination site of transcription. Silencers: regulatory elements, can be cis or trans acting. Histones proteins have "tails" that can be modified, this called histone code. Aggregate protein causes diseases: alzheimer"s disease, mad cow disease. During the process of transcription, how does the rna polymerase enzyme. Know" where to start transcribing a gene into rna. Its starts at a specific nucleotide sequence known as the promoter.
