Document Summary
Control of gene expression i: how genes are regulated, dna and proteins both contribute to the importance of gene expression. I. e heart cells, stem cells (not one that is approaching its hayflick limit) 7: control of gene suppression - what genes are expressed, at temporal and expression level. Transcript: non coding or coding, the rna sequence post transcription: product of transcription, transcriptone - is looking at all of the transcripts as a whole. Controlling gene expression: transcription initiation, don"t start the transcription process if the gene is not needed to be expressed, tissue specific transcription factors. Transcriptional - regulation of transcription initiation, this also determines which genes are transcribed (regulating the transcription process from occurring or not occurring. Posttranscriptional - rna editing after transcription has occurred, affect the functionality of the protein or whether or not it codes for a protein and its expression levels.
