Describe an example of endosymbiosis that has been observed and documented.

atroni [7]

I recall that Professor Kwang had observed amoebas that had cannibalized bacteria cells. The bacteria were slaughtering the amoebas, but somehow some survived. This particular group of amoebas contained bacteria that thrived inside it. Hence the name, endosymbiosis. However, this lucky group and it's offspring could not survive without bacteria.

Meselson and Stahl's experiments proved that DNA replicates by which mode?

Irina18 [472]

Answer:

Semi-conservative

Explanation:

Meselson–Stahl experiment proved that DNA replication is a semiconservative process, feeding E. colo bacteria with different types of Nitrogen isotopes (N14 and N15).

Changing the type of radioactive compound in different times of bacteria grow, they could observe that both of the isotopes were present on the bacteria culture.

Basically, if the bacteria present both of them, the DNA was replicated semiconcervely.

Guess what? they show both! (See the image for more information)
