When a new strand from parental DNA is synthesized then the new strand produced will be identical so why during the experiment of meselson and stahl the new strands produced in 1st generation from heavy DNA( 15N incorporated into DNA) were not identical and were not isotopes 15N but were having 14N. basically why there were not same as that of parent.?

DNA replication is a semiconservative process was proved by the experiment by Meselson and stahl. they first grew colonies of E.coli bacteria in culture medium having ammonium chloride with heavy isotope of nitrogen (N15). by this process the N15 was incorporated in nitogen containing compunds including DNA. then the bacteria was shifted into culture medium having normal nitrogen(N14). and the generation time is 20min for E.COLI . and the DNA was then isolated from each generation and tested and by density gradient centrifugation is was found that the heaviness of DNA generation having completely heavy isotope was the heaviest. and then comes the 1st generation and then the 2nd generation and so on. this proves the semiconservative nature of replication of DNA.
THE NEW STRAND FORMED WILL NOT BE TOTALLY IDENTICAL TO THE PARENT STRAND. IN REPLICATION EACH OF THE STRAND OF PARENTAL STRAND WILL FORM NEW STRAND ONE ONE EACH .
hope this answer may help you out. good luck!

Read the following text and answer the following questions on the basis of the same:In one of his experiments on interference, August Jean Fresnel used a biprism to induce interference between two beams. He split a diverging beam of light into two parts by using the biprism to refract them. This resulted in two split beams which acted as if they were from two coherent sources and which therefore interfered with each other.A Fresnel Biprism is a thin double prism placed base to base and have very small refracting angle ( 0.5°). This is equivalent to a single prism with one of its angle nearly 179° and other two of 0.5° each.In Young’s double Slits experiment, a single source is split in two coherent sources. For the Young’s slits experiment, we must approximate that the slits act as point sources. This however is not the case, since the slits have finite width. In this way, it gives rise to unwanted diffraction effects that causes errors.The Fresnel biprism experiment overcomes this problem.A Fresnel biprism is a variation of Young’s Slits experiment. When monochromatic light through a narrow slit falls on biprism that divides it into two components. One of these component is refracted from upper portion of biprism and the other one refracted through lower portion. Two virtual coherent sources formed from the original source. In this case, two virtual coherent sources are point sources and replace slits in Young’s experiment.Q. Which problem of Young’s double slit experiment is overcome by Fresnel biprism?

When a new strand from parental DNA is synthesized then the new strand produced will be identical so why during the experiment of meselson and stahl the new strands produced in 1st generation from heavy DNA( 15N incorporated into DNA) were not identical and were not isotopes 15N but were having 14N. basically why there were not same as that of parent.?
