PPT-Prokaryotes and Eukaryotes

Biology Unit 04 Lesson 01 Prokaryotes What are they Cells usually singlecelled with no nucleus Have no specialized organelles Usually have cell wall cell membrane ribosomes genetic material cytoplasm and flagella or cilia. NusA. Stabilizes the RNA pol pausing. r. -independent termination. Figure 12.9. 2. Rho-independent terminator. . contains a short . inverted repeat. (~20 . bp. ). 3. Weakest base pairing: . A:U . make the dissociation easier. GTAC. Learning Outcomes. Students recognise that there are different levels of classification – the largest being the five kingdoms which are based on cell structure.. Distinguishing plant cells from animal or fungal cells.. RNA Processing, and Transcriptional Regulation. Structure of RNA. Major Classes of RNA. Transcription in Prokaryotes. Transcription in Eukaryotes. Post-transcriptional Processing of Eukaryotic mRNA. Transcriptional Regulation in Prokaryotes:. Eubacteria & . Archarbacteria. Prokaryotes. Unicellular organisms that lack a nucleus. Prokaryotes are identified by characteristics such as shape, the chemical nature of their cell walls, the way they move, and the way they obtain energy.. PROKARYOTES. EUKARYOTES. CYTOPLASM. Cell Membrane. DNA. Always single-celled. No Nucleus. DNA is a simple,. Single loop. Small Cells. (1 – 10 . um. ). Bacteria. . Can be single- or multicellular . SC.L.14.1: The cell theory. All living things are composed of cells. They may be unicellular or . multicellular. .. The cell is the basic unit of life.. Cells arise from pre-existing cells. Prokaryotic .

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. Levels of Organization Card Sort. Lab Tables (4 group members). 5 Minutes Max. Levels of Organization Matching. 5 Minutes. Classifying Prokaryotes. The smallest and most abundant microorganisms on Earth are . prokaryotes. —unicellular organisms that lack a nucleus. . Prokaryotes have DNA, like all other cells, but their DNA is not found in a membrane-bound nuclear envelope as it is in eukaryotes. Prokaryote DNA is located in the cytoplasm. .
