BIOTECHNOLOGY TEST WITH VERIFIED SOLUTIONS #2
Biotechnology - correct answer manipulation of living organisms or their components to
produce useful products.
Cloning vector - correct answer a carrier used to transfer a gene from one organism to
another in genetic engineering (a virus, or recombinant plasmid)
Dna fingerprint - correct answer a pattern of bands on an electrophoresis gel, made up
of restriction fragments of someone's dna; can be used to identify a person at the
molecular level
Dna ligase - correct answer an enzyme that ties the ends of inserted dna in genetic
engineering (or okazaki fragments in dna replication)
Gel electrophoresis - correct answer separation of dna fragments on the basis of their
length and electrical charge
Gene cloning - correct answer production of multiple copies of a gene.
Gene therapy - correct answer insertion of normal genes into human cells to correct
genetic disorders
Genetic engineering - correct answer direct manipulation of genes for practical
purposes.
Genetically modified (gm) organism - correct answer an organism whose genes have
been intentionally manipulated; also known as a transgenic organism
Polymerase chain reaction (pcr) - correct answer technique that allows to make many
copies of a particular gene
Recombinant dna - correct answer dna produced by combining dna from different
species
Restriction enzyme - correct answer enzyme that cuts dna at a specific sequence of
nucleotides (palindrome area)
Restriction site - correct answer a specific sequence on a dna strand that is recognized
as a "cut site" by a restriction enzyme.
Ti plasmid - correct answer a plasmid of a tumor-inducing bacterium that integrates a
segment of its dna into the host chromosome of a plant; frequently used as a carrier for
genetic engineering in plants.
