The data obtained from the meselson–stahl experiment after one generation of replication eliminated the dispersive model of dna replication. True or False

Given statement is false

Explanation:

According to dispersive model of DNA replication,DNA molecules are hybrids of parental and daughter DNA;In this model each individual strand is a combination of original and new DNA

Meselson and Stahl did an experiment on DNA replication using E.coli bacteria

E.coli was grown in a medium containing heavy isotope of nitrogen,bacteria took up the nitrogen and used to synthesize new biological molecules,including DNAIt was grown for many generations,the nitrogenous bases of the bacteria's DNA were all labelled with heavy nitrogenBacteria were then switched to light nitrogen isotope and allowed to grow for several generationsThey then measured the density of the DNA using density gradient centrifugationThis method separates molecules such as DNA into bands by spinning them at high speeds in the presence of another molecule, such as cesium chlorideEach DNA produced two DNA molecules each with one new strand and one old strand called semi conservative replication(half of the parental DNA conserved in daughter DNA)Each DNA strand act as a template for synthesis of new strandHence,dispersive model of DNA was eliminated and semi-conservative model of DNA replication was proved by the above experiment

C- a hypothesis or d- an observation
