Exam 20: DNA Technology and Genetic Engineering

Prior to genetic engineering, insulin for humans with insulin-dependent diabetes was extracted from pigs and cattle. Presently insulin is produced by transgenic

What determines the specific segment of DNA that is amplified by PCR?

Gel electrophoresis is a technique used to separate a mixture of DNA fragments. During this process, large DNA fragments move longer distances than small DNA fragments when an electric current is applied.

Pharmaceutical companies prefer to genetically engineer large animals with human genes because it may be possible to obtain large amounts of the resulting protein from the animals'

Small pieces of DNA can be amplified by a process known as polymerase chain reaction.

Cystic fibrosis is a genetic disorder that is caused by the lack of a gene that encodes a cell membrane protein which transports ________ ions.

Plants that have foreign DNA inserted into their genome for the purpose of producing products beneficial to humans are referred to as

Transgenic plants can presently be used for the production of human proteins, including human serum albumin.

The techniques associated with biotechnology have allowed for fairly widespread manipulation of food available for consumption. The idea of genetically modified foods has many Americans concerned about the safety of these foods. In your opinion, are the concerns well-founded?

Insertion of a gene into another organism's DNA so that it can be transferred to another organism like a bacterium is called

The rapid development of knowledge regarding how to manipulate and analyze DNA, including techniques for modifying its structure, has led to the new field in biology known as

Short single-stranded pieces of DNA called ________ attach to a DNA template to serve as the beginning site of DNA replication.

Programmed cell death in somatic cells that are damaged is known as ________.

To create cows, sheep, and pigs that grow faster and larger, the gene for ________ has been inserted into their genomes.

Recombinant DNA technology uses a number of "tools" and components. Match each of the following to its definition. -DNA ligase
