DNA techniques Flashcards
exam 1
narcolepsy
condition characterized by sudden and uncontrollable attacks of sleep
restriction endonucleases
cuts the DNA of the phage into fragments
protected by methylation
bacterial DNA
isolated from ecoli
ECO R1
Gel elctrophoresis run from one charge to the other
from negative to positive
size of molecules on a gel electropherisis
from larger to smaller molecules
SNoW DRoP
southern blot: DNA
Northern blot: RNA
Western blot: Proteins
In a southern blot, duplex DNA needs to be turned into
single stranded DNA
southern blot, hybrydization is succesful
when the DNA fragment that we want appears in the landmark according to its size
Detection of a _____________ using Southern Blot
deletion
Detecting ____________ _______ Via Southern Blot
trinucleotide expansion
CGG repeat region
Fragile X
Trinucleotide expansion has a greater molecular weight as severity increases
southern blot
all individuals has the same mutation
sickle cell anemia
detection of the _______ _______ associated with sickle cell anemia using ____________ ________
point mutation
southern blot
single point mutation A–> T
sickle cell anemia
molecular weight changes from 1.1 to 1.3 in a southern blot
detection of sickle cell anemia
polymorphisms serve as
DNA fingerprinting
differences in polymorphisms
restriction fragment length polymorhism
altered RFLP
associated with possible mutation and diseases
FISH
Fluorescence in situ hybridization
to check for the presence, absence or copy member of the chromosome
FISH
____ is separated according to size by electrophoresis through denaturing gel and transferred to a solid support
RNA
SDS wash
Western blots–> protein neutralizing the charge
