The meselson-stahl experiment demonstrated that dna replication produces two DNA molecules each composed of the nitrogen isotopes.
<h3>
What was the conclusion of the meselson-stahl experiment?</h3>
Based on observations and experimental results, Meselson and Stahl concluded that DNA molecules can reflect semi-conservatively. Investigation of semi-conservative nature of replication of DNA or the copying of the cells, DNA failed to cease there.
1958, Matthew Meselson and Franklin Stahl carried out an test on E. coli which divides in 20 minutes, to take a look at the replication of DNA. 15N (heavy) and 14N (normal) are isotopes of nitrogen, which may be outstanding primarily based totally on their densities through centrifugation in Caesium chloride (CsCl).

Answer:
The reactants for photosynthesis are light energy, water, carbon dioxide, and chlorophyll.
<h2>Correct answer is option"e"</h2>
Explanation:
- Headache is a migraine which influences one portion of the head which endures from 2-72 hours.
- It influences a larger number of young male than young females before puberty and more young females then young male after puberty. The normal side effects incorporate retching, sickness, affect ability to light, stable and smell.
- Prevalence is characterized as the quantity of influenced people present in a populaces at a particular time partitioned by the quantity of people in the populace around then.
- Hence, the correct answer is option "e"
It occurs in eukaryotes because mitosis is the division of body cells and the human body is made up of eukaryote cells.
