When the genetic material of multiple organisms has been combined, it is called recombinant DNA.
The small unit of self-replicating DNA used as a cloning vector in genetic engineering is a bacterial plasmid.
The method of polymerase chain reaction (PCR) is used to make enough exact copies of DNA for researchers to use in analysis.
An ill or injured patient may have suffered from damaged tissues that the cell cycle, including mitosis, won't naturally repair or replace. This may include damaged nerves, or skin, or muscle. A form of biotechnology that attempts to stimulate new cell divisions with application of cells that are genetically unspecialized, is
stem cell research
The genetic molecular material that has been spliced together from multiple organisms is
The first organism (organisms) to have been produced as transgenic organisms was (were)
Before a desired gene can be spliced into a bacterial plasmid cloning vector, the gene must first be ___ from the original DNA.
cloned from the mix of recipient DNA, and
For DNA sequencing, the technological process called ___ separates DNA fragments that have already been isolated and cut into different lengths.
Examine this diagram of short tandem repeats found in DNA profiling of three suspects in a crime. Man 1 shares the same number of STRs as 1 in 5,000 people. Man 2 shares the same number of STRs as 1 in 10,000 people. Man 3 shares the same number of STRs as 1 in 3,500 people. DNA extracted from samples at the crime scene found 6 STR repeats, giving the interpretation that
Man 2 is likely guilty, considering that he has a rare STR profile that matches crime scene samples.
Identify the correct comparison in the genetic characteristics between embryonic and adult stem cells.
Embryonic stem cells can produce any of the differentiated cells, while adult stem cells can't.
Many plants, fungi, and even animals can asexually reproduce new genetic copies of themselves because fragments survive. This is a natural version of
The method used to produce the cloned sheep, Dolly, was
somatic cell nuclear transfer.
After identifying a specific protein associated with a medical problem, the corresponding gene can identified with a ___, which is radioactively or fluorescently tagged.
A couple, both carriers of Cystic Fibrosis alleles, can prepare for a child being born with the disease, by testing with
preimplantation genetic diagnosis.
Preimplantation genetic diagnosis is one form of biotechnology associated with the fertility technology of
in vitro fertilization.
After a cell has been removed from an embryo for preimplantation genetic diagnosis, the embryo
will continue to grow and develop.
