Explanation:
The DNA could be dried -through the process of lyophilization- or stored, as a precipitate of ethanol, in liquid nitrogen (temperatures below -80 degrees Celsius). The aim is to reduce water in the stored samples as much as possible because the water can be involved in natural hydrolytic reactions (depurination, depyrimidination, deamination, and hydrolytic cleavage) that could degrade the nucleic acids of the DNA.
If the DNA is stored while being used regularly it is not advisable to store it as a precipitate of ethanol. It should be stored in aqueous form but in a slightly alkaline pH of about 8.5 to prevent acid-catalysed degradation processes.

I believe the ratio of C to H to O in simple sugars or monosaccharides are 1 C : 2 H : 1 O or 1:2:1.
Answer:
CHK2, p53, p21, cell cycle progression.
Explanation:
In a normal cell with no LFS mutation, during the G1 stage of cell cycle progression, the CHK2 activates if there is damage in the DNA. CHK2 activates p53, which is a tumor suppressor protein that will hold the cell cycle in G1/S until the DNA is repaired. The p53 protein activates p21, a protein that binds to CDK2 and stops the cell cycle. The cell cycle will continue once the damage is repaired.
Answer:
answer; if u adjust the diagram on the chart it should be a little bit narrow and small but exact the diagram consist different altitudes and scopes. use
Explanation:
why well because think about it your question is what happens when the diagram on the microscope adjusts to easily.
Answer:
C. The differences between the observed and expected counts are too large to be attributed to chance.
Explanation:
The p-value of the statistic represents the chance that the observed count is based on luck or chance. When p value too high, the research can't be used since the chance that its not represent real condition are too high. Most researchers use 5% (0.05) as the cutoff of something called statistically significant. In this research, the p-value is 0.04 or 4%, so it is statistically significant.
