11 Amazing Facts about DNA You didn’t Know.

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. […]

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 Journey of genetic material from Nuclein to DNA started with the discovery of Nuclein by Meischer and ended with the Hershey-Chase Experiment. There was a time during this journey when the battle for the title of genetic material was fought between Protein and DNA. But, at the end, DNA unequivocally won the battle and was considered as the genetic material of most of the cell. […]
