Sodium vs Potassium. Sodium and Potassium are naturally occurring alkaline metals that show many similarities in their behaviors. Both sodium and potassium ions are essential for all life forms. Both ions are highly reactive and easily dissolve in water which is why both are found more in seawater than on land.

Transcription factor, molecule that controls the activity of a gene by determining whether the geneâs DNA (deoxyribonucleic acid) is transcribed into RNA (ribonucleic acid). The enzyme RNA polymerase catalyzes the chemical reactions that synthesize RNA, using the geneâs DNA as a template. Transcription factors control when, where, and how efficiently RNA polymerases function.
