Which of the following mutations would likely be most dangerous to a cell?A. Deletion of one nucleotideB. Deletion of three nucl
Harlamova29_29 [7]

Answer:

A

Explanation:

The reason the deletion of a nucleotide can be a lethal mutation is that it causes a frameshift mutation. This is due to teh fact that the codon sequence on the DNA is shifted by a single nucleotide. Therefore, the codons will read differently downstream from the place the deletion happened. The amino acids coded for by these codons will change too. The translated proteins will be defective and the organisms will be adversely affected, phenotypically.

SOMEONE PLEASE HELP ME!!!
Lynna [10]

By understanding DNA and gene expression, humans have been able to understand how genetic diseases are caused, therefore they have been able to devise gene therapy and other technologies to treat such disease. Second, the understanding has also allowed humans to devise plants that are resistant to pests and drought hence increasing crop yields.

A negative aspect of this understanding is the issue of bioterrorism. In the wrong hands, this technology can be used against society. The technology can be used to modify organisms to make them deliberately harmful to humans. Second is the issue of bioethics. This technology can be used to enhance humans and result to an ‘arms race’ between human races that can tear down the social fabric.

How will the stomata look with high water pressure
dalvyx [7]
The stomata of leaves are surrounded by guard cells. The guard cells help the leaves to regulate the rate of transpiration of water from the leaves by opening and closing the stomata. When water enter the guard cells, they swell and bulge and this makes the stomata to open. So, with high water pressure, the guard cells will stimulate the stomata to open. The reverse will be the case if the water pressure is low.
