Question

The science dealing with the study of phenomena at very low temperature is known as:-
1. Frozenics
2. Cytogenics
3. Refrigenics
4. Cryogenics

Answer 1

Correct Answer - Option 4 : Cryogenics

The correct answer is Cryogenics.

• Cryogenics is the production of and behavior of materials at very low temperatures.
• Ultra-cold temperatures change the chemical properties of materials, which provide an interesting area of study for researchers who wish to examine the materials as they transition from gas to liquid to a solid-state.
• The temperature of any material is the measure of the energy that it contains. Rapidly moving molecules have a higher temperature than slower-moving molecules.
• Cryogenics can be used to produce cryogenic fields for rockets, in MRI machines that use liquid helium and require cryogenic cooling, storing large quantities of food, special effects fog, recycling, freezing blood and tissue samples, and even cooling superconductors.

 

• Cytogenetics is the branch of genetics that studies the structure of DNA within the cell nucleus.
  • This DNA is condensed during cell division and form chromosomes.
  • The cytogenetic studies the number and morphology of chromosomes.
  • In modern times we can use advanced cytogenetics techniques such as fluorescence in situ hybridization (FISH) to look at the genetic material in the cell through a light microscope but at a much higher resolution.
