Answer #1

Eukaryotic cells have something on the order of 1000 times more genetic material (DNA) than bacteria. Viral DNA is much smaller than even bacterial DNA. Prokaryotic cells (bacteria and other) do not have their DNA sequestered inside a nucleus; in a sense, the prokaryotic cell is much like the nucleus of a eukaryotic cell in the way it functions. Both contain long strands of DNA. A virus generally contains a single chunk of DNA. Both eukaryotic and prokaryotic cells replicate mostly via mitosis. Viruses replicate by invading a host cell of a prokaryote or eukaryote, inserting themselves into the host DNA and getting the host to do the replication for them.

7)  Select the true statements about how bacteria can get new genetic material.  Circle all that apply. Conjugation can occur only between bacteria of the same species. In transformation, bacteria can pick up pieces of bacterial DNA from their surroundings. It is necessary for viruses to be lysogenic for restricted transduction to occur. In transduction, bacterial genes end up in viral capsids. Bacterial conjugation can use pili, which act as pseudopods, engulfing genes from another bacterium to incorporate them into the cell’s...

We discussed the endosome system that viruses sometimes use to get their genetic material into the host cytoplasm. A. Imagine an endosome that maintains a pH of 5 under normal conditions when no hydroxychloroquine is present. Explain how an endocytic pump could use ATP to create such an acidic pH. B.Now imagine that hydroxychloroquine is suddenly present in the endosome. Explain the process that will happen to the hyroxychloroquine, the endosome pH, and the endocytic pump?

Even before the structure of DNA was solved, studies indicated that the genetic material must have the following properties: -be able to store information; -be faithfully replicated and be passed on from generation to generation; and -allow for changes, and thus evolution, to occur. Explain how the structure of the double helix showed that DNA had these properties. Write one or two sentences per point.
