In recent times, the people of India have been heard talking about gene sequencing, gene editing, gene sequencing, and many other similar terms. It seems like, they are now getting introduced to the idea and principle behind personal genomics. Continue reading Personal Genomics: Gene Sequencing & Analysis in India.
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. Continue reading What are SNPs? Why are Scientists interested in them?
Gregor Johann Mendel was the first to visualize a gene as a discrete, stable particulate unit of inheritance in 1865. He called it a factor and postulated that the offspring receive some specific factors from their parents which make parents characters to appear in the offspring. The term “Gene” was introduced by Johansson in 1909 for a unit of heredity located at a specific site, the locus, in a chromosome. Continue reading What are Genes?
