A genetic engineer wants to isolate a gene from a scorpion that encodes the deadly toxin found in its stinger, with the ultimate

purpose of transferring this gene to bacteria and producing the toxin for use as a commercial pesticide. Isolating the gene requires a DNA library. Should the genetic engineer create a genomic library or a cDNA library

Answer:

The correct answer is - Yes, the genetic engineer should create a genomic library or a cDNA library.

Explanation:

mRNA isolated from the toxin extracted from the venom gland of the scorpion to create a cDNA library. The cDNA sequence is reverse transcribed by the mRNA that lacks the introns as prokaryotic organisms such as bacteria cannot splice introns.

If the engineer wants to express the toxin in bacteria then he required a cDNA sequence as a genomic clone can not use to clone for making proteins.  mRNA should be isolated from the venom gland so it can synthesize cDNA library enriched with toxin protein sequence.

Furkat [3]

Answer:

The use of left arm is more compared to right hand

Explanation:

In the given question, the anthropologist when examines the left and right arm he found that the left arm is thicker than the right arm.

The more thickness of the left arm signifies that the person uses his left arm for the muscular work as the more use of hand increases the deposition of the calcium phosphate and sulfate in bones along with other material which increases the thickness for the bones and increases the strength.

Thus, The use of the left arm is more compared to the right hand is correct.
