Meselson and Stahl conducted an experiment in 1958, and discovered that DNA replication was semiconservative. In semiconservative replication, when the double stranded DNA helix is replicated each of the two new double-stranded DNA helixes consisted of one strand from the original helix and one newly synthesized.
Watson and Crick mentioned it slightly in their paper but didn't propose a full method of replication. a number of different people collaborated to work out the full model of replication which is still no totaly finished, (few proteins left to find)
the reason for this experiment was to clarify how DNA replicates.There were 3 suggested models :the conservative.the semiconservative and the dispersive model. The experiment proved that DNA replicates in a semiconservative way i.e each of the parental strands serves as a template for the composition of a new strand.
The process of DNA replication is semi-conservative. Which means, in the new (daughter) DNA double helices that are formed, one strand belongs to the parent strand (also referred to as the template strand) and the other is a newly synthesized strand. Subsequently, every new DNA molecule that is formed as a result of the replication process has one original parent strand and one newly synthesized complimentary strand.
I'm not an expert on this subject but as I've learned, DNA is split into two replication forks where the complimentary base pairs and other backbones are added on, so ideally it would be 50% of the original strand in each daughter strand.
The alcohol lamp was invented by Johann Wolfgang Döbereiner in 1823. Döbereiner was a German chemist known for his work in developing new laboratory equipment and improving chemical reactions.
Watson and Crick mentioned it slightly in their paper but didn't propose a full method of replication. a number of different people collaborated to work out the full model of replication which is still no totaly finished, (few proteins left to find)
Francis Crick, James Watson, and Rosalind Franklin provided evidence for the semi-conservative replication of DNA through their research on the structure of DNA. Their work ultimately led to the groundbreaking discovery that new DNA is synthesized by copying strands of the existing DNA molecule.
