Explanation:MESELSON-STAHL EXPERIMENT is an experiment carried out by Matthew Meselson and Franklin Stahl in the year 1958 which supported Watson and Crick's hypothesis that DNA replication was semiconservative.
After the completion of the first replication cycle,it was discovered that the replication is not a complete conservative process but a semi-conservative in nature. It shows that when DNA replicates one of the Helical strand is from the
one strand from the original or old helix and one newly synthesized helix.
Explanation: DNA isolated after one generation produced a single band which was a higher and intermediate in density between the heavy and light Nitrogen isotopic DNA used, showing that the first generation was a hybrid DNA. This observation fit with the dispersive and semi-conservative models only. And so at this generation, the conservative model was discarded.
You will be okay after eating a high-calorie meal as long as it is not eaten often. However, eating more calories than calories that can be burned can cause weight gain.
Vacuoles store water, food, and waste. The endoplasmic reticulum (ER) is a series of tunnels throughout the cytoplasm. They transport proteins from one part of the cell to another. Ribosomes are the protein factories of the cell.
