| Direction: Read the following and answer the questions from given below |
| The Meselson and Stahl experiment was an experiment to prove that DNA replication was semiconservative and it was first shown in Escherichia coli and subsequently in higher organisms, such as plants and human cells. Semiconservative replication means that when the double stranded DNA helix was replicated, each of the two double-stranded helices consisted of one strand coming from the parental helix and one is newly synthesised. |
| (iii) Similar experiments like Meselson and Stahl was performed by Taylor in 1958. The experimental organism of Taylor was |
A) Vicia faba
B) Fungi
C) E. coli
D) Protista
Correct Answer: A
Solution :
[a] An experiment similar to Meselson and Stahl experiment was performed on Viciafaba by Taylor and his collaegues in 1958. These experiments proved that the DNA in chromosome also replicate semiconservatively.
