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:
<h2>What is a biome?</h2>
A biome is an area classified according to the
species that live in that location . Temperature
range, soil type, and the amount of light and
water are unique to a particular place and form
the niches for specific species allowing scientists
to define the biome.
<h2>How does it relate to an Ecosystem?</h2>
<h3>Ecosystem</h3>
An ecosystem is a geographic area where plants,
animals, and other organisms, as well as weather and
landscapes, work together to form a bubble of life.
