Quote of the day

On a student's test paper on Organisation and Control of Prokaryotic and Eucharyotic Genomes
Lao Tze said,"A journey of a thousand miles begins with a single step"

I say , "Cancer development begins with a single cell."

Now that is quite an insight, he was referring to the Multi-step model of Cancer Development which basically involves the gain in function (through eg. mutations) of proto-oncogenes and the loss of function mutations in tumour suppressor genes that lead to the development of cancer, starting off from a single cell.
