Genes that come from No Where!

Genetics has come a long way since the 1950’s. Although there has been progress made in unravelling the mysteries of our molecular heritage, we are constantly stumped by newer facts about our genetic code. And the one that leads the way is the mystery about Junk DNA.

Genes, our molecular hereditary information, although bulky and cumbersome have a methodical way of working. Genes are transcribed into RNA which in turn are coded into protein, and these proteins finally get involved in the molecular build-up of our existence, thus making the genes where they come from, the foundation of it all.



But not all of the gene or genetic material is really coded into protein. There is a major portion which is left out of this entire process and is not capable of coding for protein; this is called ‘junk DNA’. Interesting facts about ‘junk DNA’ have baffled the world of science, like the ‘junk DNA’ constitutes almost 95% of the human genome!

For years the scientific world was intrigued by these '…
