Arvind Pendse walked the audience through the story of how the Genetic code was deciphered.
Most people have heard words like DNA, chromosomes, genes and genetic code and probably have a vague idea that genes contain a manual of instructions that runs our life, both mental and physical. All living beings have such an instruction manual inside them. However, people may not be aware that the language in which this manual is written and the way the instructions are executed is the SAME in ALL LIVING BEINGS. Content is obviously different but the language and its execution is the same right from single celled amoeba to complex human beings.
This talk was about a detective story i.e. the long journey to uncover the fascinating mystery that had always puzzled mankind. Mystery about how life works, how this information is stored in us, and how it is passed on from generation to generation. How these questions were resolved by deciphering the genetic code in many small logical steps with co operation of many scientists from many countries working together.
The story has many twists and turns, shows how the scientists also make silly mistakes, how they also have biases and reject sound logical ideas, but how the self correcting scientific method prevails to uncover the truth in the end. Along the way Arvind talked about what is meant by scientific method and why it is probably the best tool we have to uncover truth.
