DNA is the genetic material in all except certain viruses. In Prokaryotic cells, DNA occurs in the cytoplasm and is the only component of the chromosomes. Whereas, in Eukaryotic cells, DNA is largely confined to the nucleus. Do you know, A human DNA contains 3 billion chemical letters. Yes, it is true. There are several other amazing and fun facts about DNA that we don’t know.

Personal Genomics: Gene Sequencing & Analysis in India.
In recent times, the people of India have been heard talking about gene sequencing, gene editing, gene analysis and many other similar terms. Gene or genome sequencing is a process or method of figuring out the order of DNA nucleotides or bases in a human genome. It comes under the umbrella of personal genomics.
What are SNPs? Why are Scientists interested in them?
A most common and important source of genetic variability is known to be present uniformly throughout the genome is termed Single Nucleotide Polymorphisms or SNPs. Interest in SNPs lies in the fact that these polymorphisms may be responsible for the differences in disease susceptibility, drug metabolism and response to environmental factors between individuals. Even, if they are not directly responsible for the disease, they serve as genetic markers for a nearby locus that might be responsible.
Who discovered that DNA is the Genetic Material?
The discovery of DNA as the genetic material was one of the major achievements of science in the 20th century. This discovery made DNA, the chemical basis of heredity. It took almost 80…
