First Plasmid is a chromosomal element often a circular DNA.
The uptake of a plasmid from the environment is NOT a common event reason being, bacteria naturally take up DNA from their environment in a process called transformation. Thus if a bacterium takes up a piece of DNA that cannot be maintained in a cell then that cell will not survive.
Answer:
Explanation:
A. The bacteria DNA will contain most of the radioactivity. The reason is that the DNA is made up of a sugar phosphate backbone which forms its structural framework. One grinding up the bacteria, the radioactive phosphate will likely react with the DNA.
B. In the second instance, the proteins will contain the radioactivity this is because, the DNA does not have any reaction with sulphur, on the other hand, proteins contain about 3 - 6% sulphur.
Answer:
Interphase is the longest phase in the cell cycle.
