Our genetic material is a big molecule of DNA or deoxyribonucleic acid, whose structure is a double-stranded wound-up helix. It contains specific instructions that run a living cell, and these instructions are written on the strands. When cells divide, the DNA replicates too. In this process, the contents of the strands are read and copied carefully by unwinding the strands. But that's not as simple!
New research reveals that a unique Indian skink species arrived on the subcontinent by rafting across the ocean from Southeast Asia millions of years ago, a journey made possible by fluctuating sea levels.
