Answer:
B. The smaller DNA pieces travel farthest towards the positive end of the box
Explanation:
Gel-electrophoresis technique is a technique which is used to separate the fragments of DNA based on their size. The technique is employed in the DNA fingerprint analysis.
The DNA samples are loaded on one side of the gel and when an electric current is applied, the DNA moves from the wells towards the electrodes.
The DNA is a negatively charged molecule which travels through pores in the gel and reaches towards the electrode with positive charge.
The smaller the size of the DNA fragment, the faster it moves.
Thus, Option-B is correct.
Lashley is looking at different ways in which the brain works, especially different parts of the brain. If part of the brain was damaged and you compare how well the rat completed the task before and after the damage, then you can determine what function that part of the brain does. Also, if you study how well the rat completes the task as time progress, you can see if the rat is able to use other parts of the brain to "learn" and repair the damaged part of the brain.
Hello Kenzie,
Logically each of the statements seem right except the first one A for the reason it doesn't sound right and its not how politics work. With this said im thiinking A is the answer
A. False. The order in which amino acids are linked is unique for each protein and isthe most important factor in determining overall protein structure.
B. False. Peptide bonds are planar amide bonds that are central to the polypeptide
backbone formation. The atoms in the amino acid side chains are not considered
to be part of the backbone.
C. True.
D. True.
<span>The answer would be:
Jellies
Salt cured meats
Honey
High osmotic pressure can be used as a natural preservative. In high osmotic pressure, the microbes will hardly survive as their surrounding concentration is too high and induce severe osmosis. The osmosis will take the microbes water, makes it shrink continually lead to the microbes death.
In those 3 foods, there is a high concentration of sugar or salt that increase the osmotic pressure.</span>
