Lecture 31: Cloning of DNA
Reading material: Horton, Chapter 24 in 2nd Ed; 23 in 3rd Ed (Stryer: Chapter 6)
Abstract: Recombinant DNA technology has revolutionized biochemistry. Some of the methods will be summarized:
Restriction enzymes cleave DNA specifically. DNA can be sequenced by using
dideoxynucleotides. Plasmides and phages can be used for DNA cloning in bacteria. Genomic and cDNA libraries can be constructed. A particular gene can be amplified by the polymerase chain reaction (PCR).
Key concepts:
Restriction enzymes
Blotting techniques
The Sanger dideoxy method of DNA sequencing
Synthetic nucleotide synthesis
Vectors
Libraries
PCR
cDNA
Cloning
