PPT-Gene regulation in prokaryotes and

Eukaryotes By prof Sawsan Sajid AL Jubori   transcription  and its regulation in prokaryotics is much simpler But the eukaryotes have to transcribe and then have a process for mRNA processing like capping splicing and adding ply adenine tail and then have a special mechanism to transport the processed mature mRNA to the cytoplasm from the nucleus. Cell Theory. Every living organism consists of one or more cells.. The cell is the structural and functional unit of life.. All living cells arise by division of preexisting cells.. Cells contain hereditary material, which they pass on to their offspring during division.. Pre-transcriptional regulation. chromatin compaction . eg. . deacetylation. , . methylation. transcriptional initiation . ie. transcription factors to activate or repress. alternative promoters =. Prokaryotic . Structure. size1-5. m. m (resolution of the human eye ~750. m. m). . Cell wall. . main component is peptidoglycan (modified sugar polymers). . can be further differentiated performing a gram stain . Single-celled organisms. Very tiny. Cannot be seen without a microscope. Our microscopes are not powerful enough. Lack a nucleus and most other organelles. Most numerous organisms on Earth. Extremely important organisms.. Structure of RNA. Major Classes of RNA. Transcription in Prokaryotes. Transcription in Eukaryotes. Post-transcriptional Processing of Eukaryotic mRNA. Transcriptional Regulation in Prokaryotes:. the Lac Operon as an example. Biology Unit 04 Lesson 01. Prokaryotes – What are they?. Cells (usually single-celled) with no nucleus. Have no specialized organelles. Usually have: cell wall, cell membrane, ribosomes, genetic material, cytoplasm, and flagella or cilia. GET READY TO USE THEM. STAND UP NOW . WITH CLICKERS IN HAND. WHEN I GIVE THE SIGNAL,. HOLD YOUR BREATH AS LONG AS YOU CAN.. I will count the time off.. When you can’t hold your breath any longer,. Draw 8 boxes on your paper. Gene regulation accounts for some of the phenotypic differences between organisms with similar genes.. 2005-2006. Gene regulation in bacteria. Control of gene expression enables individual bacteria to adjust their metabolism to environmental change. microscopic single celled organisms. collective biomass – . 10x of all eukaryotes!!!!!. vast genetic diversity among members. physical diversity. shapes: . spheres (. coccus. ), rods (bacilli) and spirals. What makes these two cell classes different?. Cells. The . cell. is the smallest unit of life in the universe.. ALL cells have two things in common:. They have . cell membranes. , which are barriers that separate the inside of a cell from the outside.. Warm Up- 8/21. What level of organization is this picture an example of?. Good Things.
