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.
Answer:
Yes, it is possible to get shingles more than once.
Explanation:
Women are more likely to have shingles a second time more than men.
The longer the post herpetic neuralgia ( pain after shingles) the higher the chances of recurrence.
If shingles comes back, it may occur on another side of the body. This is because, once you have had chicken pox, the virus remains in the nerve. When the virus then reactivates the infected nerves become inflamed and when the virus reaches the skin, the rash appears.
Well for one, we used coal for electricity, water for steam engines when they were much in use, natural fossil feuls for our gasoline and oil, and we use earths oxygen/nitrogen gasses to breathe and sadly we are polluting it at a fast rate
Because we can't take in light energy directly, we consume plants. Plants convert light energy into chemical energy through the process of photosynthesis. So when we eat plants, we get the chemical energy stored in the carbohydrates, which fuels all our physical activity.
Answer:
If a single base in the sequence is missing, this mutation could affect and disturb the whole frame-shift of protein synthesis
Explanation:
A single base missing or deletion will result in DNA mutation and will cause changes in the translated protein which will alter the function of the protein and sometimes the translated protein product is non functional.
