In 1915, the scientist Thomas Hunt Morgan discovered that certain genes on chromosomes are associated with specific traits in fruit flies. However, the mechanism through which this process occurs was not detailed until 1966. That is when Marshall Nirenberg and several other scientists demonstrated that specific sequences of nucleotides in DNA correspond to specific proteins. After gene sequencing was introduced in 1977, scientists were able to use Nirenberg's discoveries to predict an organism's proteins from its DNA sequences.
How does the information above illustrate the nature of science?
A.
It shows that scientific progress is made primarily through observational rather than experimental evidence.
B.
It shows that earlier scientific ideas are typically incorrect since genes code for proteins and not traits.
C.
It shows that scientific ideas are durable but are developed as new data are collected.
D.
It shows that scientists like Nirenberg did not rely on ideas of others in making major discoveries.
