Whose work first connected mutations to changes in DNA sequence?
Human BiologyGenetics
Quick Answer
The connection between mutation and DNA sequence emerged from mid-20th-century molecular genetics. It became clear after the genetic code and DNA structure were understood.
The Full Story
No single scientist made this link in one step, but the idea solidified in the 1950s and 1960s as molecular biology developed. Once DNA’s structure and the genetic code were understood, researchers could show that mutations are changes in the nucleotide sequence. This explained how inherited differences can alter proteins and traits. The concept underlies modern genetics, including disease testing and genome sequencing.
Key Facts
1.DNA uses four bases: A, T, C, and G
2.The genetic code was cracked in the 1960s
3.Mutations are changes in DNA sequence
