• AAA is the only code for Serine.

• AUG codes for both methionine and Valine

• Histidine is coded by AAG.

• Isoleucine is the only amino acid coded for by AUU.

How did the various contributions of scientists pictured further knowledge on the structure and function of DNA?

• It showed how scientists' collaborate with each other to further scientific discoveries.

• It showed that the mitochondria and chloroplast, which have their own DNA, were once prokaryotes engulfed by a larger prokaryote in a symbiotic relationship.

• It proved that the nucleus contained the genetic material for every cell and that genetic material is DNA.

• It concluded that all living cells contain DNA.

What key scientific concept is shown by the discovery of DNA molecule by X-RAY diffraction in 1952 and the physical model in 1953?

• Hypothesis testing

• laboratory techniques

• data analysis

• nature of science
