Genetic Technology Flashcards
(11 cards)
agarose gel
used to separate DNA molecules of different sequence lengths
polyacrylamide
use to separate proteins of various amino acid lengths
blotting
used to detect molecules & preserve the same for later
southern blotting
detection of specific DNA sequences
Northern blotting
detects RNA
western blotting
detects specific proteins
PCR - polymerase chain reaction
what are the 3 steps used?
- denaturing - the DNA (98 degrees C)
- annealing - complimentary nucleotides called primes attach to the single stranded templates (50-65 degrees C)
- Extension - by attaching bases (72 degrees C)
DNA cloning
used for gene amplification
DNA sequencing
used for analysis of DNA
Restriction fragment length polymorphism (RFLPs) `
restriction enzymes bind to & cut the dsDNA; a different fragment length lets you know there is a difference in the specific sequence within the individual
Gel electrophoresis
separates molecules of different sizes using a charge gradient
