D. darkness
The diagram below represents a common
laboratory technique in molecular genetics.
The ounder is a species of sh that can live in
very cold water. The sh produces an “antifreeze”
protein that prevents ice crystals from forming in
its blood. The DNA for this protein has been
identi ed. An enzyme is used to cut and remove
this section of ounder DNA that is then spliced
into the DNA of a strawberry plant. As a result,
the plant can now produce a protein that makes
it more resistant to the damaging e ects of frost.
This process is known as
A.
sorting of genes
B.
genetic engineering
C.
recombination of chromosomes
One common use of this technology is the
D. mutation by deletion of genetic material
A.
production of a human embryo to aid women
who are unable to have children
B.
change of single-celled organisms to
multicellular organisms
C.
introduction of a toxic substance to kill
bacterial cells
D. production of hormones or enzymes to replace
missing human body chemicals
