Answer 1

Answer #1

A. In order to release DNA from strawberry or banana, then this is a plant cell. So we have to break the cellulose cell wall, then plasma membrane and then the nuclear membrane will be broken.

B. For isolation of DNA from bacterial cell, we need to break the peptidoglycan cell wall followed by plasma membrane and then DNA will come out. Nucleus and nuclear membrane are absent in bacteria. If the bacteria contains capsule, then we have to remove the capsule as well.

C. Human beings does not have cell wall. So cell membrane and nuclear membrane will be broken for isolation of DNA.

Please rate high.

2. Research how antibiotics affect bacterial cells. Which cell structure(s) are typically targeted? Based on this information do you think human cells are affected by the antibiotics? Include references to information sources used. 3. As mentioned in the introduction, both humans and fungi are eukaryotic. Looking at the structures found in human and fungal cells, propose one possible cellular target that would impact fungal cells but not human cells.

The speed of DNA replication at a replication fork is about 100 nucleotides per second per standin human cells. What is the minimum number of origins of replication that a human cell must have in order to replicate its DNA once every 24 hours? Recall that a human cell contains two copies of the human genome, one inherited from the mother and one from the father, each consisting of 3 x 109base pairs.

Could you help with part 2 the executioner portion of this question? Thanks The proper cellular ATP levels are critical for almost all cell function (-1mM in the cytoplasm). In this problem set you will propose different mechanisms how a cell could regulate and maintain this ATP level. Your proposed mechanisms don't have to exist (do not read up online about the way cells regulate ATP levels!). But the mechanisms should be plausible and based on what you learned in...
