Q:

Why are yeast cells frequently used as hosts for cloning?

A) they are eukaryotic cells B) they do not have plasmids
C) only yeast cells allow the gene to be cloned D) they easily form colonies
 
Answer & Explanation Answer: A) they are eukaryotic cells

Explanation:

If you were to produce a protein in bacterial cloning systems, you would not get the same post transcriptional and post translational modifications because the prokaryotic and eukaryotic systems work differently on the modifications.

Thus human recombinant protein genes are usually cloned in yeast cells. Also since they have a short generation time, they can be easily culture.

C) Ethylene D) Ethyl Alcohol
 
Answer & Explanation Answer: C) Ethylene

Explanation:

Ethylene is used for Artificial Ripening of Green Fruit.

    • Calcium carbide is also used in some countries for artificially ripening fruit. When calcium carbide comes in contact with moisture, it produces acetylene gas, which is quite similar in its effects to the natural ripening agent, ethylene

Q:

A capillary tube is partially dipped vertically in a vessel containing water. Due to capillarity  water rises in the tube. The height of water rise in the tube can be increased by 

A) decreasing the radius of the capillary tube B) increasing the radius of the capillary tube
C) increasing the height of water in the vessel D) None of these
 
Answer & Explanation Answer: A) decreasing the radius of the capillary tube

Explanation:

The water rise in a capillary tube dipped in water is such that the weight of water in the tube above the surface of water in the vessel is equal to (balances) the upward force due to surface tension. So it is clear that if the the bore (radius) to the tube is decreased, the height of the water column in it must be greater.  So, (a) is correct.
