Chapter Outline. Transcription in Prokaryotes. Eukaryotic RNA Polymerases and General Transcription Factors. Regulation of Transcription in Eukaryotes. RNA Processing and Turnover. TSW – Recognize that the presence of a nucleus determines whether a cell is prokaryotic or eukaryotic. 6.12B. Cells. There are two . basic types . of cells. Prokaryotes. or prokaryotic cells . Eukaryotes. Eukaryotic Gene Regulation. How are genes turned on & off . in eukaryotes?. How do cells with the same genes differentiate to perform completely different, specialized functions?. Evolution of gene regulation. Kingdom Protista. A. Sometimes not considered a true kingdom because the organisms vary tremendously from one to another. The only universal characteristic among the group is that they are all eukaryotic.. 2. Terminology . Genome. – entire genetic material of an individual. Transcriptome. – set of transcribed sequences. Proteome. – set of proteins encoded by the genome. . Gene. * Basic . physical and functional units of heredity.. Gene Expression Group. 7/14/11. 2011 National Academies Northstar Institute for Undergraduate Education in Biology . Outline. Context. Review: Clicker Questions. Cell Differences (Think-Pair-Share). Regulation of Gene Expression (Mini-Lecture). Structure dictates function . Prokaryotic transcription is simpler. DNA exists in one chromosome . Less non-coding sequence. RNA polymerase binds the promoter directly. Genes are clustered into functional groups called operons. Two Basic Types. Remember….cells are the basic unit of life for ALL living things.. There are two basic types of cells:. Prokaryotic cells . – found in bacteria. Eukaryotic cells . – found in . Multicellular. . Organisms. Overview. Review of key structural and genetic features of eukaryotic cells.. Remind yourself of these by your own reading. .. The origin of cells with eukaryotic organization, some 2.5 . Eukaryotic Cell. 3. Eu. = True. Karyon. = Nucleus. B- The Eukaryotic Cell. Animal Cell. Plant Cell. Compare Animal and Plant cell. What are the functions of cell organelles . ?. Copyright © 2002 Pearson Education, Inc., publishing as Benjamin Cummings. Gene Regulation Gene expression can be turned on, turned off, turned up or turned down! For example, as test time approaches, some of you may note that stomach acid production increases dramatically&# Definition:. Anything genetic above and beyond the . sequence. of nucleotides. Importance:. Everything. , especially development and genetic. responses to the environment.. Examples of Epigenesis:. 1) Development: tissue differentiation and timing. AP Bio – Ch. 16-21.

A single guiding RNA (sgRNA; . a fusion of . tracrRNA. and crRNA. ) . binds CAS9 protein at one end, the other end guides CAS9 to target DNA sequence based on complementarity. . Gene for the CAS9 protein, encodes endonuclease, cuts both strands of the target sequence.
