What are two examples of probes?
It is helpful to consider the following terms to understand better what gene probes are about:
- RNA: Ribonucleic acid (RNA) is a molecule similar to DNA. ...
- Radioactive material: the radioactive or fluorescent material could be an isotope, a dye, or an enzyme. ...
- Nucleic acid: Nucleic acids are a class of macromolecules found in all cells and viruses. ...
- Base pair: A base pair is two chemical bases bonded together and forming the DNA ladder. ...

What are the four types of probes?
The probes can be divided into 4 basic categories: the lin- ear probe, the loop probe, the side-by-side probe and the concentric probe ( fig. 3 ) [10] .
What are the two types of probes?
There are two common types of probes suitable for use with the instrument: active and resistive divider (passive).
What is a probe in ultrasound?
An ultrasound transducer, also called a probe, is a device that produces sound waves that bounce off body tissues and make echoes. The transducer also receives the echoes and sends them to a computer that uses them to create an image called sonogram.
What are 3 types of probes?
There are three basic types of probe used in emergency and critical care point-of-care ultrasound: linear, curvilinear, and phased array. Linear (also sometimes called vascular) probes are generally high frequency, better for imaging superficial structures and vessels, and are also often called a vascular probe.
How many types of probes are used in CRO?
two typesCRO probes can be classified into the following two types. Now, let us discuss about these two types of probes one by one.
How many space probes are there?
Missions – NASA Solar System Exploration. More than 250 robotic spacecraft—and 24 humans—have ventured into space since we first began exploring beyond Earth's atmosphere in 1958.
What is a 10 1 probe?
The 10:1 designation indicates that the probe attenuates the signal by a factor of 10. A probe of a 100-V signal causes 10 V to appear at the oscilloscope input. In most instruments, the oscilloscope senses the probe attenuation and displays the actual voltage at the DUI output.
What is 10x probe?
Ten – X probes are the “standard” probes supplied with most scopes. They reduce signal amplitude by a factor of ten. Usually by incorporating a 9 megaohm resistor in the probe tip to act as a voltage divider. This added attenuation makes 10x probes good for high-voltage measurements.
What are 3 uses of ultrasound?
Doctors commonly use ultrasound to study a developing fetus (unborn baby), a person's abdominal and pelvic organs, muscles and tendons, or their heart and blood vessels. Other names for an ultrasound scan include sonogram or (when imaging the heart) an echocardiogram.
What is convex probe?
Convex probes (also called curved linear probes) have a curved array that allows for a wider field of view at a lower frequency. Convex probes are primarily used for abdominal scans due to their wider depth and deeper penetration.
Which probe is used in echo?
In echocardiography we use curvilinear probes. These have a small footprint (surface from which the ultrasound rays are emitted). Curvilinear probes emit the ultrasound beams in the form of a wave front. This is done by sequentially firing one element after the other.

What is a probe in recombinant DNA technology?
A probe is a single-stranded sequence of DNA or RNA used to search for its complementary sequence in a sample genome. The probe is placed into contact with the sample under conditions that allow the probe sequence to hybridize with its complementary sequence.
