Eukaryotic Gene Regulation. Almost all the cells in an organism are genetically identical.. Differences between cell types result from . differential gene expression. , the expression of different genes by cells with the same genome.. CONSTITUTIVE GENE PRODUCTS ARE NEEDED BY THE BODY AT ALL TIMES. TUMOR SUPRESSOR PROTEINS. ATP. ENZYMES THAT CONTROL CELLULAR RESPIRATION. ADAPTIVE GENE PRODUCTS ARE ONLY REQUIRED UNDER CERTAIN CONDITIONS. Learning Objectives. Learn what a ‘transcription factor’ is.. Learn how oestrogen affects gene transcription.. Learn what siRNA is and how it affects gene expression.. Recap of 15.1. That the cells in our bodies are highly . The DNA inherited by organisms leads to specific traits by dictating synthesis of proteins . The process by which DNA directs protein synthesis is called . Gene Expression. Transcription. Translation. 1. The information content of genes is in the form of specific sequences of nucleotides along the DNA . strands. The . DNA of an organism leads to specific traits by dictating the synthesis of proteins and of RNA molecules involved in protein synthesis (. Anablep. . anablep. . with its “4 eyes”. Upper half of lids look aerially while the lower half looks into the water.. Cells of the two parts of the eye exhibit differential gene expression. Individual bacteria respond to environmental change by regulating their gene expression. 1. The information content of genes is in the form of specific sequences of nucleotides along the DNA . strands. The . DNA of an organism leads to specific traits by dictating the synthesis of proteins and of RNA molecules involved in protein synthesis (. TUMOR SUPRESSOR PROTEINS. ATP. ENZYMES THAT CONTROL CELLULAR RESPIRATION. ADAPTIVE GENE PRODUCTS ARE ONLY REQUIRED UNDER CERTAIN CONDITIONS. GENES FOR PROTEIN DIGESTION ARE TURNED OFF WHEN THERE IS NO PROTEIN AVAILABLE. . (Chapter 9). Presented by Dr. Laurie M. Erickson. Chair of the Department of Health Sciences. Blitstein Institute of Hebrew Theological College. Chicago, IL, USA.. Gene Expression can be Regulated.. Gene expression: . 10.1 Types of RNA. DNA vs RNA. DNA vs RNA. Translation. Micro RNA (miRNA). Types of RNA Molecules. Chapter 10: Transcription and RNA Processing. 10.2 RNA Polymerase Enzymes. Transcription Initiation. Central Dogma. The direction of the . flow of genetic information. is from DNA to RNA to polypeptide.. DNA Replication. Initiation and Unwinding of DNA. DNA . gyrase. . (. topoisomerase. ) unwinds the DNA coil.. Mechanism of regulation of gene expression- An overview. Gene activity is controlled first and foremost at the level of transcription.. Much of this control is achieved through the interplay between proteins that bind to specific DNA sequences and their DNA binding sites. . , Transcription Factors, and Chromatin Remodeling The Gene • Complex collection of sequences that o Controls a phenotype ▪ Individually • OR ▪ Complexed with the action of other genes • Acknowledgement.
