Document Summary

Side note: activators bind to enhancer gene sites; repressors bind to silencer gene sites, ultimately slowing transcription: the formation of the transcription initiation complex provides stability, and allows. Rna polymerase ii to be recruited, so transcription can begin; various transcription factors also regulate the rate, speed and length of the transcriptional process. How does this process differ in prokaryotes: when rna polymerase ii reaches the end of the coding region, it is usually signalled by many adenines (a nucleotides) to dissociate/detach from the dna. Note: sequence of exons correspond to an area of the protein once translation is complete. Example: alternative splicing of tropomyosin in smooth muscle and skeletal muscle: a nucleotide mismatch has been left uncorrected and lies right at the position of the signal sequence for intron 1. Side note: mutations also make retroviruses very difficult to eradicate.
