Biology Question on Genetics and Evolution
Who performed experiments on Vicia faba to prove that the DNA replicates semi-conservatively?
A
Taylor and colleagues
B
Matthew Meselson
C
Stahl
D
Hershey and Chase
Answer
Taylor and colleagues
Explanation
Solution
Taylor and his colleagues used root tips of Vicia faba (broad bean) to demonstrate that DNA replication follows a semi-conservative mechanism. In this method, each daughter DNA molecule consists of one original (parental) strand and one newly synthesized strand. This experiment laid the foundation for understanding how genetic information is conserved during cell division.
