genetic quiz 4 finals Flashcards
(40 cards)
The use of living organisms or substances they produce in
the development of products or processes that are beneficial
to humans.
biotechnology
Recombinant methods also enable the introduction of genetic
material into animals and plants, resulting in
genetically
modified organisms (GMOs).
an organism that has received genetic
material from a different species
Transgenic organism
a gene from one species that is introduced into
another species.
Transgene
Recombinant techniques
can improve strains of
microorganisms
USES OF MICROORGANISMS
removed
from cattle and pigs.
pancreases
Insulin is a hormone composed of two different polypeptide
chains, called the
A and B chains.
comprising β-galactosidase and either the A or B
chain.
Fusion protein
which
cleaves the fusion protein after a methionine that is found at the
junction between β-galactosidase and the A or B chain.
cyanogen bromide (CNBr),
use of living organisms or their products to
alleviate plant diseases or damage from environmental
conditions.
Biological control-
prevent disease in several ways.
Biological control agents-
are used to compete
effectively against pathogenic strains for nutrients or space.
Nonpathogenic microorganisms
to prevent
crown gall disease caused by
Agrobacterium tumefaciens.
Agrobacterium radiobacter
produces agrocin 84, a
small-molecule antibiotic that kills A.
tumefaciens.
A. radiobacter
contains a plasmid with
genes that encode enzymes responsible for
the synthesis of agrocin 84.
A. radiobacter
lethal to many
caterpillars and beetles
Bacillus thuringiensis,
use of living organisms or their products
to decrease pollutants in the environment.
Bioremediation-
during bioremediation via
microorganisms, enzymes produced by a microorganism
modify a toxic pollutant by altering or transforming its
structure
Biotransformation-
in which the toxic pollutant is degraded,
yielding less complex, nontoxic metabolites.
Biodegradation-
Another way to alter the toxicity of organic pollutants is
polymerization.
aimed at altering the sequence of a gene.
Gene modification-
-Cas technology can inactivate a gene by introducing
a deletion in it. It can alter a gene sequence by introducing a
specific mutation, such as a missense mutation, into a gene.
CRISPR
involves the insertion of a cloned gene into a
genome
Gene addition-
in which a gene of interest
has been inserted into a particular
site
gene
knockin
