Chapter 21 Flashcards
Genetic Testing and Treatment.
A gene expression microarray has
short pieces of DNA of known sequence attached to a small plastic or glass square.
The requirements for patenting of an invention involving DNA in the U.S. are that it should be
new, useful, and not obvious to an expert in the field.
One of the earliest uses of biotechnology was
using yeast to ferment fruit into wine.
Structures used in recombinant DNA technology to carry the DNA from the cells of one species to the cells of another species are
cloning vectors.
Proteins isolated from bacteria and used in recombinant DNA technology to cut DNA at specific sequences are
restriction enzymes.
In 2010, a federal judge in the U.S. ruled seven patents on the BRCA1 and BRCA2 genes had been improperly granted.
true.
Recombinant DNA technology is used to
create many copies of a specific piece of DNA.
If part of a DNA template is the sequence GTTAGTCTGTGGGCT, then the mRNA transcribed from it is
CAAUCAGACACCCGA.
The first drug produced using recombinant DNA technology was
insulin.
Bacteriophages can be used as vectors in recombinant DNA experiments because they
insert their genetic material into bacteria.
The linear order of amino acids in a polypeptide is the __________ structure of a protein.
primary.
Restriction enzymes are useful in creating recombinant DNA molecules because they
generate “sticky ends” by cutting at the same sequence in any DNA source.
The process in which bacteria with the ability to detoxify certain pollutants are released in a particular area is known as
bioremediation.
Bacteriophages can be used as vectors in recombinant DNA experiments because they
insert their genetic material into bacteria.
A DNA sequence can be patented if
it is useful as a tool for research or as a novel or improved product.
