This can help turn genes up or down without changing the gene code itself. DNA methylation helps normal cells stay stable, repair damage and … Read more
Key Takeaways Bioelectric Basics Charge Across Membranes Cells separate charged minerals between the inside and outside of the membrane. This separation creates a voltage, often called the resting membrane potential, and it exists in almost every living cell. Voltage in biology describes a difference in electrical charge, not a store of usable power like a … Read more
