BIOL 200 Lecture Notes - Lecture 7: Tata Box, Molecular Cloning, Plasmid
Document Summary
Biol 200 - lecture 7, regulatory sequences in protein cording genes. Body is consisted of many different types of cells that each have specific functions. During development, different cells will express different genes, which will lead to a different expression of proteins. Transcription regulation mrna splicing mrna export mrna degradation. Each step has to be controlled very precisely for the body to function properly. Expression of the eukaryotic protein coding gene is regulated through the multiple protein-biding transcription-control regions located at various distances from the transcription start site. Many places and elements in the a gene that regulate the transcription. Direct biding of rna polymerase ii to dna. The promoter is essential for transcription, if there is no promoter, there is no transcription. For this course, the promoter will be the tata box, or any other sequence that recruits rna polymerase to the transcription start site. Most of the genes have a tata box.
