Answer:
Hypernatremia
Hypernatremia is
a condition that infers too much salt and less water in the body, which could
result to dehydration where the person is thirsty for plain water after eating
a salty fish. There are sensors in the body that could detect saltiness of the
blood and this sends signals to the brain that the body needs water to dilute
the salt and balance the fluids in the cells. Therefore, making the person feel thirsty for water.
The correct answer is: introns
Processing of mRNA is process that occurs only in eukaryotic cells. After the transcription, newly formed mRNA molecule is called and it must be processed into a messenger RNA (mRNA). Processing includes:
• Addition of a 5' cap to the beginning of the RNA
• Polyadenilation- addition of a poly-A tail (tail of A nucleotides) to the end of the RNA
• Splicing- removal of introns and linking the exons
After these steps mRNA is mature and used for the further steps (e.g. translation).
Sometimes some genes are alternatively spliced.
