PPT-7.3 Transcription in prokaryotes

731 State that transcription is carried out in a 5 3 direction Nucleotides are added in the form of ribonucleoside triphosphates 732 Distinguish between the sense and antisense strands of DNA. 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.. 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 . 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.. Structure & Function. Dr.Qurat-Ul-Ain. Department Of Microbiology. KEMU,Lahore. . Two Basic Types of Cells. _____________________. ______________. Size of Living Things. 1 m = 100 cm = 1,000mm = 1,000,000 . 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.. 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,. microscopic single celled organisms. collective biomass – . 10x of all eukaryotes!!!!!. vast genetic diversity among members. physical diversity. shapes: . spheres (. coccus. ), rods (bacilli) and spirals.

Domains of living cells. . Principles of microbial cell structure . Elements of Microbial cell Structure. Eukaryotes. . Prokaryotes & chemistry of cellular components . 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. .
