Front Back
Plasmid
Are small circular DNA molecules that replicate separately from the bacterial chromosome
Recombinant plasmid
Artificially constructed plasmids with a desired gene
Recombinant dna
Artificially constructed dna with desired genes inserted using sticky ends
Genetic engineering
The deliberate modification of the characteristics of an organism by manipulating its genetic material.
Bacteriophage
A virus that parasitizes a bacterium by infecting it and reproducing inside it. used to insert genes into cells
Cloning vector
A DNA molecule that can carry foreign DNA into a host cell and replicate there
Restriction enzymes
Cut DNA molecules at specific DNA sequences called restriction sites
Restriction fragments
A restriction enzyme usually makes many cuts, yielding
Sticky ends
The most useful restriction enzymes cut DNA in a staggered way
BAC
Is a large plasmid that has been trimmed down and can carry a large DNA insert. another type of vector used in DNA library construction
YAC
Behave normally in mitosis and can carry more DNA than a plasmid as vectors helps avoid gene expression problems in eukaryotic cells
Genomic libraries
•made using bacteria is the collection of recombinant vector clones produced by cloning DNA fragments from an entire genome made using bacteriophages is stored as a collection of phage clones
Nucleic acid probe
A clone carrying the gene of interest can be identified with a
Nucleic acid hybridization
Proces used to determine if a clone has a desired trait. make complementary gene and see if it produces the protien
Gel electrophoresis
Method used to sequence dna where fragments are pulled through a porus gel and then read under a uv light
