voice from miles away‚ and it is that voice that gave me my first taste of the art of genetics. Mr. Jones’ spritely energy sparked my fascination with the most phenomenal language on earth that every living creature shares. Constructing the double helix with pipe cleaners and jelly beans‚ memorizing how transcription occurs or cutting and pasting karyotypes together constituted only a tiny fraction of the information Mr. Jones instilled in me. Through this preliminary study‚ pieces of my own life

They created this drug to help women with morning sickness. Before Dr. Frances Kelsey worked for the FDA‚ it was already being marketed to forty-six different countries (Helix‚ Connecting Science to You). When it was sent to the FDA for approval to be sold in the United States it was given to Dr. Frances Kelsey as her first drug to approve while working for them. Dr. Frances Kelsey started working for the FDA in the 1960’s

It was Photo 51‚ a photo taken by Rosalind Franklin that Wilkins didn’t have permission to take. “According to Watson‚ photo 51 provided the vital clue to the double helix” (Cobb).

THE SCIENTIFIC METHOD A ‘Hypotheses‚’ said Medawar in 1964‚ ‘are imaginative and inspirational in character’; they are ‘adventures of the mind’. He was arguing in favour of the position taken by Karl Popper in The Logic of Scientific Discovery (1972‚ 3rd edition) that the nature of scientific method is hypothetico-deductive and not‚ as is generally believed‚ inductive. B It is essential that you‚ as an intending researcher‚ understand the difference between these two interpretations of the
