Amplification (pronounced am-pluh-fi-key-shuh-n) involves
extending a sentence or phrase in order to further explain, emphasize, or exaggerate certain points of a definition
, description, or argument. Amplification can involve embellishment or technical elaboration. Either way, more information is being added.
What does amplification mean in biology?
Definition. In molecular biology, amplification is
a process by which a nucleic acid molecule is enzymatically copied to generate a progeny population with the same sequence as the parental one
. The most widely used amplification method is Polymerase Chain Reaction (PCR).
What is meant by amplification in physics?
(physics) The act, or result of independently increasing some quantity, especially voltage, power or current. … The act
or result of amplifying
, enlarging, or extending.
What is mean by amplification of signal?
The use of specific detection methodologies to directly increase the signal in proportion to the amount of target in the reaction
.
What is the term amplification?
Amplification (pronounced am-pluh-fi-key-shuh-n) involves
extending a sentence or phrase in order to further explain, emphasize, or exaggerate certain points of a definition
, description, or argument. Amplification can involve embellishment or technical elaboration. Either way, more information is being added.
What is an example of amplification?
In literature, amplification means the writer is adding more information to a sentence. … For example, “
The dog is an excellent breed
” can benefit from a bit of amplification. As such, the writer might say, “The dog is an excellent breed, full of intelligence, loyalty, and overall healthfulness.”
What is amplification used for?
“In amplification, writers repeat something they’ve just said while adding more details and information to the original description. . . “The main purpose of amplification is
to focus the reader’s attention on an idea he or she might otherwise miss.
“
How is amplification done?
The amplification of gene is done by using
the technique of PCR
. PCR stands for Polymerase Chain reaction. PCR enables the production or amplification of billions of copies of an original piece of DNA in the tube with minutes or hours.
Why do we need PCR amplification?
PCR
allows the amplification of DNA sequencing in an exponential way using repeated thermal cycling
. PCR allows the generation of many millions of copies of DNA using heating and cooling cycles. As a result, many people are now using PCR in their research all over the world.
Why is gene amplification used?
Gene Amplification
Cancer cells sometimes
produce multiple copies of genes in response to signals from other cells or their environment
. The term also can refer to polymerase chain reaction (PCR), a laboratory technique that is used by scientists to amplify gene sequences in a test tube.
What does DNA amplification require?
To amplify a segment of DNA using PCR, the sample is first heated so the
DNA denatures
, or separates into two pieces of single-stranded DNA. Next, an enzyme called “Taq polymerase” synthesizes – builds – two new strands of DNA, using the original strands as templates.
What is amplification of light?
Light amplification is
the process of intensifying the amplitude of an electromagnetic light wave
. … Laser amplification is associated with the linear polarization which occurs due to first-order atomic susceptibility in an optical medium.
What is amplification in transistor?
Transistor is electronic solid state semiconductor device which regulates electric current flow and acts as a switch or gate for electronic signals. A transistor consists of three layers of a semiconductor material. … Similarly, Amplification is
the process of increasing the strength of a SIGNAL
.
How does signal amplification occur?
When a signaling molecule joins with an appropriate receptor on a cell surface
, this binding triggers a chain of events that not only carries the signal to the cell interior, but amplifies it as well. Cells can also send signaling molecules to other cells.
What is an example of signal amplification?
Signal amplification, for example, results
in a liver cell releasing many glucose molecules after detecting just a single molecule of epinephrine
. Signal amplification can occur at many points. For example, as long as epinephrine remains bound to a receptor, the receptor can activate a succession of G proteins.
What is voltage amplification?
:
the ratio of the alternating voltage produced at the output terminals of an amplifier to the alternating voltage impressed at the input terminals
.
