While the introduction of the mutant synthetase gene restored some of the growth characteristics, this strain still does not gro

w as fast as wild-type E. coli. Which of the statements support this observation?
A) The mutant synthetase gene allows histidine tRNA to be charged with asparagine, but sometimes this tRNA could deliver asparagine in the place of histidine to other proteins where the histidine residue was important to the function of the protein and growth.B) The mutant synthetase gene allows histidine tRNA to be charged with asparagine, therefore histidine could not be present in any protein. If the the histidine residue was important to the function of various other proteins growth may not be completely restored.C) The codon for histidine has not changed in the mutant variant, therefore only the mutant variant of the protein is produced resulting in slow growth.D) The normal synthetase that charges histidine tRNA with histidine is still present resulting in the mutant variant of the protein. Not having enough of the normal protein may still limit growth.

Answer:

A and D

Explanation:

Transfer ribonucleic acid (tRNA) is a type of RNA that decodes mRNA (messenger RNA) into protein. This phenomenon is known as translation.

If the strain of mutant synthetase gene does not grow fast despite having growth characteristics, the following possibilities could happen:

  • Sometimes histidine tRNA sends asparagine instead of histidine to other proteins where histidine residue should have been present for growth.
  • The normal synthetase might be present but not in an adequate amount.

How does the cell structure of prokaryotes impact reproduction?
Softa [21]

Answer:

Reproduction in prokaryotes is asexual and usually takes place by binary fission. Recall that the DNA of a prokaryote exists as a single, circular chromosome. Prokaryotes do not undergo mitosis. Rather the chromosome is replicated and the two resulting copies separate from one another due to the growth of the cell.

Explanation:

Hi again! Thank you so much for the points.

How does the skeletal system interact with the nervous system?
Mice21 [21]

Answer:

The skeletal muscles connect to the bones and work with connective tissue at the joints to allow for movement. The muscles connect to the nervous system and allow initiation of movement through nerve signals to and from the brain. The bones and muscles are supported by connective tissue, which plays an integral role in structural support.
