Lab session Protein - Isolation and analysis - Electrophoresis and concentration determination - Western technique Lab session Genetic engineering - DNA cloning and plasmid design - Transformation and competent cell preparation - Lab session -Oral presentations Introduction of some concepts Micro and macro molecules Micro-molecules: Glucose, amino acids ….etc. Macro-molecules DNA, RNA and proteins Isolation of macromolecules Break the cell open This process is called cell lysis Cells must be placed in a buffer solution during the lysis process. why? Isolation of macromolecules Hierarchy & Protein Function Protein Folding II Regulation of Protein Function by Degradation electrophoresis SDS-PAGE Introduction to genetics What is the genetic material S and R bacterial cells Streprococcus pneumonia Hershy –Chase “blender” experiment using T2 bacteriophage Bacteriophage How genes are transmitted from parents to offspring? Classical or mendelian genetics Gregory Mendel experiment on Garden peas 1856-1863 Classical genetics depends on: Phenotype: color , size , texture…etc. Genotype: The genetic make up of the organism. Inheritance of seed texture Morphological phenotype W is dominant over the w Inheritance of seed texture Molecular phenotype Mendel first experiment Inheritance of Genetic trait(s) Mendel first experiment reciprocal cross Results of Mendel first experiment Explanation of 3 dominant :1 recessive inheritance Monohybrid cross Independent assortment Segregation The principal of the 3:1 inheritance Phenotype: Genotype:
