BIOLOGY BIOTECHNOLOGY QUIZ WITH ANSWERS #11
Biotechnology - correct answer process of manipulating organisms, cells or molecules
to produce specific products
Restriction enzymes - correct answer enzymes that cut dna into precise pieces at
different sequences of base pairs
Gel electrophoresis - correct answer procedure used to separate and analyze dna
fragments by placing a mixture of those fragments at one end of a porous gel and
applying electrical voltage to the gel
Dna fingerprinting - correct answer tool used by biologists that analyzes an individual's
unique collection of dna restriction fragments; used to determine whether two samples
of genetic material are from the same person
Plasmids - correct answer small accessory dna molecules that provide antibiotic
resistance
Recombinant dna - correct answer dna produced by combining dna from different
sources
Dna microarray big definition - correct answer glass slide or silicon chip that carries
thousands of different kinds of single-stranded dna fragments arranged in a grid. Used
to detect and measure the expression of thousands of genes at once
Polymerase chain reaction (pcr) - correct answer the technique used by biologists to
make many copies of a particular gene
Dna extraction allows scientists to... - correct answer isolate dna
Gel electrophoresis allows scientists to... - correct answer sort dna strands according to
length
The final product of running a gel is... - correct answer the fingerprint, or image of where
the dna landed
Dna extraction is necessary because it allows for... - correct answer genetic testing,
body identification, and analysis of forensic evidence
Pcr stands for... - correct answer polymerase chain reaction
Pcr helps people... - correct answer focus in on one dna segment and copy it billions of
times
