PPT-Prokaryotic gene regulation

Group 1 Akhtar Ali Lucile McCook Marcella Hackney Sarah Lea Anglin Anne Grove Facilitator Prokaryotic gene regulation Context Target Audience Intro Biology for Freshmen DNA structure. 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. A. Generalized Structure. 1. Cell Appendages. A) Flagella. 1) Functions in movement of the cell. 2) 3 components. Prokaryotic Cell Structure. a) Filament . i) Whip-like, helical structure. b) Hook . i) Holds the filament. 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. 2.2.1, 2.2.2: Ultrastructure of . E.coli. Mesosome. Plasmid. 2.2.3: Electron micrograph of . E.coli. Nucleoid region. cytoplasm. IB Question: . Draw and label a generalized prokaryotic cell as seen under the electron microscope. . Eukaryotes, Prokaryotes and Measuring Cells. Lesson Objectives. To understand the difference between eukaryotic and prokaryotic cells.. To describe the features of a prokaryotic cell such as a bacterium.. 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. A. Generalized Structure. 1. Cell Appendages. A) Flagella. 1) Functions in movement of the cell. 2) 3 components. Prokaryotic Cell Structure. a) Filament . i) Whip-like, helical structure. b) Hook . i) Holds the filament. Endosymbiosis. h. eterotrophic eukaryote. Examine these diagrams showing . how an ancestor to eukaryotic cells may have engulfed smaller heterotrophic prokaryotic cells that began producing ATP for it. Pre-transcriptional regulation. chromatin compaction . eg. . deacetylation. , . methylation. transcriptional initiation . ie. transcription factors to activate or repress. alternative promoters =. 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 . CHAPTER 27. PROKARYOTIC ADAPTATIONS. typical prokaryote:. 0.5 -5 microns. unicellular. variety of shapes. cocci. (spherical). bacilli (rods). spirochetes (corkscrews). Cell-Surface Structures. nearly all have cell wall. CSCOPE. Unit: 08 Lesson: 01. There are hundreds of different types of cells in your body, and each type has a unique function. We’re going to compare some different types of cells to see how much they have in common. . (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: . 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.
