MOLECULAR GENETICS Flashcards
is a method for separation and analysis of macromolecules (DNA, RNA and proteins) and their fragments, based on their size and charge.
Gel electrophoresis
Oligonucleotides are short, single-stranded DNA or RNA molecules that have a wide range of applications in genetic testing, research, and forensics.
Oligonuceotides
are enzymes that cleave the phosphodiester bond within a polynucleotide chain
Endonuceases
detection of a specific DNA sequence in DNA samples
Southern blot
process of determining the precise order of nucleotides within a DNA molecule
DNA sequencing
used to assemble recombinant DNA molecules and to direct their replication within host organisms.
DNA cloning
assist in the identification of individuals by their respective DNA profiles
DNA finger printing
to amplify a single or a few copies of a piece of DNA across several orders of magnitude, generating thousands to millions of copies of a particular DNA sequence
Polymerase chain reaction
collection of microscopic DNA spots attached to a solid surface
DNA microarray
the use of DNA as a drug to treat disease by delivering therapeutic DNA into a patient’s cells
Gene therapy
Altered DNA that results from the insertion of a sequence of deoxyribonucleotides not previously present into an existing molecule of DNA
Recombinant DNA
DNA containing sequences derived from two different species (eg, humans and bacteria
Chimeric DNA
Association of complementary strands of nucleic acids
Hybridization
after separation, labeled oligonucleotides placed in contact with an X-ray film; will show labeled substances as dark bands
Auturadiography
cleaves DNA about 25 bp from the recognition sequence
Type III
cleaves the DNA within the recognition sequence itself; requires no ATPrecognition sequences are usually 4-6
TYPE II
Cleaves both strands of DNA at opposing phosphodiester bonds leaving no unpaired base on the ends
Blunt ends
