Answer:
So the mnemonic that I know is SNOW DROP. Southern=DNA, Northern=RNA, O=O, and Western=Protein. The question asks, "Which technique CANNOT be used to analyze gene expression?" and the answer is Southern because it is a "techniue used to detect a particular sequence in a sample of DNA."
Do u still need help I know how to do that
Answer:
The correct answer is "cell lysis due to the effect of osmotic pressure".
Explanation:
The cell wall is a structure that brings protection from the outside world and also helps to maintain the cell's water balance. The cell wall prevents that the cells is exposed to a large amount of turgor pressure, making the cell turgid when it is under extremal conditions. Some antimicrobials, such as bacitracin, block cell wall synthesis which makes the cell unable to support turgor pressure, resulting in cell lysis due to the effect of osmotic pressure.
DNA is deoxyribonucleic acid, which is insoluble in ethanol. In the process of centrifugation the addition of ethanol can aid to separate protein from its DNA.
<h3>What is centrifugation?</h3>
Centrifugation is a process of separating different molecules in a given sample that have different densities by rotating them in solution around an axis at high speed.
It is the frequently applied techniques in the molecular biology laboratory.
The addition of alcohol or ethanol to the sample followed by centrifugation can separate the proteins from its DNA.
Thus, the substance used to separate the proteins from the DNA is alcohol or ethanol.
