Which of the following statements is false?
a. Plasmids can be exchanged between different species of bacteria.
b. The blue circle represents a small chromosome.
c. The blue circle is a plasmid that contains genes that confer resistance to specific antiobiotics.
d. The blue circle represents a double-stranded molecule of DNA.
How can i explain my answers in depth in microbology for example this question: Assume that there are horizontal gene transfers between two completely different bacterial species. In one case it is a plasmid that is transferred via conjugation, in the other case it is a part of the bacterial chromosome that is transferred via transformation.
In which of the two cases is it most likely that the transferred DNA will remain and be able to function in the recipient cells?
Explain the biological background to your answer . How do I break down the question so I answer it fully
If a viral host cell has a mutation that interferes with the addition of carbohydrates to proteins (glycoproteins) during processing in the Golgi
apparatus, which of the following processes is most likely to occur?
O A. Viruses released by that host cell would have a decreased ability to infect cells than the virus that originally infected the cell.
B. The virus-encoded protease would be unable to cleave large viral proteins into smaller, functional polypeptides.
OC. The virus would be unable to replicate within the host cell.
D. Viruses released by that cell are novel and would result in infections with higher mortality rates.

There are many thousands of different proteins in a cell, and they mediate the cell’s metabolism, producing the traits and characteristics of a species. Researchers working with DNA viruses proved that it is DNA that stores and passes on genes. They worked with viruses with an outer coat of protein and a DNA strand inside. How did they prove that it was DNA, not protein, which is the primary source of heritable information?arrow_forward
