1 answer:

4 0

<span>Latrotoxin produced by widow spider affects muscle nerve endings. This toxin forms pores on the membrane of the cell. As a consequence, an influx of Ca+ ions occurs and bursts of the neurotransmitter acetylcholine (Ach) are released. Ach induces an increase in neuromuscular activity that leads to painful skeletal muscle spasms and later even paralysis.</span>

If you were to repeat the Meselson Stahl experiments, but rather than use N15 and N14, you use P32 and P31, how would the result

Answer:

The correct answer will be option-C

Explanation:

The CsCl gradient centrifugation in Meselson Stahl experiments is done to separate the bands of the DNA containing isotopes on the basis of difference in the density.

In the experiment, bacterial cultures were grown in the medium of 15N and 14N but if we repeat the experiment with P32 and P31 instead of 15N and 14N and centrifugation is performed then the banding pattern will be the same as of the previous experiment as the method of the replication is same that is semi-conservative.

Thus, Option-C is the correct answer.
