What did Frederick Sanger develop at the Laboratory of Molecular Biology?
The first-ever DNA sequencing technique
The first-ever protein sequencing technique
The first-ever cell culturing technique
The first-ever RNA replication technique
Answer
The first-ever DNA sequencing technique was developed by Frederick Sanger at the Laboratory of Molecular Biology. He used a technique called chain-termination sequencing, which is still used today. In this technique, DNA is copied using a DNA polymerase, but one of the nucleotides in the reaction mixture is modified so that it does not add to the growing DNA chain.
