What is the expected percent change in the DNA content of a typical eukaryotic cell as it progresses through the cell cycle from
Anastasy [175]

The question is incomplete. The complete question is:

Question: What is the expected percent change in the DNA content of a typical eukaryotic cell as it progresses through the cell cycle from the start of the G1 phase to the end of the G2 phase

a. -100%

b. -50%

c. +50%

d. +100%

Answer:

d. +100%

Explanation:

S phase comes between G1 and G2 phases of the interphase of a cell cycle. S phase of interphase includes replication of DNA. The process of DNA replication doubles the amount of DNA present in the cell. The newly synthesized DNA is accommodated in the sister chromatids of chromosomes. Therefore, a cell with 2C DNA in the G1 phase would have 4C DNA at the end of the G2 phase. So, there is a +100% increase in the DNA content of a cell as it proceeds from G1 to the end of the G2 phase.

Enzyme hot spring graphing what enzymes probably came from the digestive tract of the mondoni
AURORKA [14]
I found the full exercise on the internet and it describes that there are three enzymes and you want to know which are the two enzymes from the <span>digestive tract of the mondoni and which one is the enzyme from a hot spring.
Attached are two graphs from the analysis of the activity of these enzymes regarding temperature and pH. I found these graphs with the full exercise.
The enzymes that probably came from the </span>digestive tract of the mondoni were enzymes A and B. These enzymes were resistant two lower levels of pH which indicates that they could be present in a <span>digestive tract, which tends to be acidic, while the enzyme C does not tolerate lower pH levels. Enzymes A and B were also more active when in lower temperatures that match temperatures of a normal living organism, whereas enzyme C was more active in higher temperatures matching its probable provenience - a hot spring.</span>
