Answer:
The synthesis of RNA from a DNA template.
Explanation:
We know that transcription is the first step in gene expression. In the transcription process, information from a gene is used to build a functional product such as a protein. The primary goal of transcription is to produce an RNA copy of a gene's from a DNA sequence.
For a protein-coding gene, the RNA copy, or transcript, carries that information that is needed to build a polypeptide.
Eukaryotic transcripts need to go through some processing steps before starting of translation into proteins.
Potassium is 10 to 20 times higher inside the cell, and sodium is 10 to 20 times higher outside the cell. The potential difference across the cell is important in several processes such as transmission of nerve impulses and maintain the ion balance.
The sodium concentration higher out side and potassium higher inside the cell then it moves two potassium into the cell where potassium levels are high and pump three sodium ions out of the cell and into the extracellular fluid.
This is due to action of membrane active transport system which pumps sodium out of the cell and potassium into it. Both helps in body maintain flid and blood volume so it can function normally.
