What is the full form of DNA?
Table of Contents
The full form of DNA is Deoxyribonucleic Acid.
Who discovered DNA?
DNA was first discovered and identified by Swiss biologist Johannes Friedrich miescher in 1869 during his research on white blood cells.
The double helix structure of a DNA molecule was later discovered through experimental data by James Waston and francis crick. Finally, it proved DNA is responsible for storing genetic information in living organisms.
What is DNA?
Deoxyribonucleic Acid is a molecule composed of two polynucleotide chains that coil around each other to carry the genetic instruction for growth, function, and development and reproduction in all known organisms and many viruses.
Most of DNA is located in the cell nucleus ( where it called nuclear DNA) , but small.amounts of DNA can also be found in the mitochondria ( where it is called mitochondria DNA or mtDNA).
The function of DNA:
1. DNA is responsible for the hereditary material in humans and almost all other organisms.
2. The change which occurs in the DNA sequence is called Mutation.
3. DNA replication: DNA replication is an important process that occurs during cell division. It is also called as semi-conservative replication, during which DNA makes a copy of itself.
4. DNA fingerprinting
5. Gene therapy
6. cellular metabolism.
