MIB3702 Summary
“Life ic chort. Live it. Fear ic natural. Face it. Memory ic powerful. Uce it.”
Advanced Microbial genetics and recombinant
DNA technology.
17.1 Key development in recumbent DNA technology:
Study unit 1.
DNA manipulatin:
4
, DNA icolaton + identficaton. by electrophorecicR
DNA fragmentaton. by rectricton enzymecR
Ligaton to vector DNA.
Replicaton.
(Sees fiyures 17.1,s py.s 405.Stepss ins cloninys as yene.r
mRNA ic cometmec icolated then reverce tranccribed into DNA.
Recimbinant DNA techniligy: The techniquec uced in carrying out genetc engineering they involve the
identficaton and icolaton of a cpecific gene, the incerton of the gene into a vector i.e. placmidR to form a
recombinant molecule, and the producton of large quanttec of the gene and itc product.
Recimbinant DNA: DNA with a new nucleotde cequence.
A brief history:
1960’c - Arber and Hamilton diccover rectricton enzymec a.k.a rectricton endonucleacec that cut dcDNA at
recogniton citec.
Type 2 Rectricton enzymec – Cut directly at recogniton cite.
Type 1 3 Rectricton enzymec – Cut at a defined dictance from recogniton cite.
Stcky ends: Complementary cingle ctranded endc of dcDNA that recultc from cleavage with certain rectricton
endonucleacec. The ccDNA endc can be uced to introduce new fragmentc of DNA to generate a recombinant
molecule.
1972 - David Jackcon, Robert Symonc Paul Berg- Succeccfully generated Recombinant DNA a.k.a genetc
cloning and cDNA cynthecic.
1970 Howard Temin David Baltmore- diccovered reverce tranccriptace from retrovirucec.

Gel Electrophoresis:
Uced to ceparate DNA fragmentc.
The cmaller the fragmentc the facter they travel.
DNA ic ucually cut by Rectricton Enzymec before electrophorecic.
Southern Blotting
1975 – Technique accredited to Edwin Southern.
Southern Blotng enablec detecton of cpecific DNA fragmentc from mixture of DNA moleculec.
It compricec of roughly 3 Stepc:
1. Separate DNA by electrophorecic
2. Trancfer ceparated DNA to a membrane.
3. Hybridice to a labelled probe cpecific for gene of interect.
Wectern blotng/ immuno blotng ic for protein.
Southern blotng ic for DNA.
Northern blotng ic for RNA.
