Some of the symptoms of hyponatremia include headaches, muscle cramps or spasm, seizures, weakness, restlessness, and confusion. Hyponatremia can occur from excess fluid in the body, or a loss of sodium in body fluid.
Explanation:
True
Changes in the transcription of mRNA or the translation of a polypeptide are not considered to be mutations because they are not permanent changes to the cell.
Explanation:
The half-life of mRNA and proteins is short. mRNA has an average of 10 hours of life span while proteins have an average of several days. Therefore mutation in these biomolecules will only persist as long as this mutated mRNA of protein exists. After its life-span, the molecule is degraded and replaced by a non-mutated mRNA or proteins. This is because the piece of DNA that codes for the mRNA and subsequent protein is not mutated. A mutation on DNA is the permanent kind of mutations because DNA is a highly stable molecule that stores information about the cell.
