How does the Griffith experiment connect to the Meselson & Stahl experiment? How does this experiment support Meselson & Stahl’s experiment?

CHALLENGE ACCEPTED!!

Explanation:

THE GRIFFITH EXPERIMENT demonstrated that something in the virulent s strain of pneumococcus could transform non virulent r strain bacteria into a lethal form, even when the s strain bacteria had been killed by the high temperature.

So the two experiments aim at determining the replication mechanism.

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.
