<h2>Sodium channels </h2>
Explanation:
Depolarization is a result of sodium channels opening as a result of chemical or pressure-based stimuli     
- Depolarization starts when a threshold stimulus applied on a neuron via Na+ mechanically operated channels that trigger action potential 
- Action potential is an efficient signaling process by which distantly located cells communicate to each other 
- Depolarization of membrane potential is due to influx of Na+ via voltage gated Na+ channels 
- Fast opening of voltage gated Na+ channel shifts membrane potential from -70mV to + 50mV at which voltage gated Na+ channels become inactive thus influx of Na+ abruptly stops

Answer:
Chromosomes are made up of  DNA(deoxyribosenucleicacid) which is a protein complex called chromatin that is organized into subunits called nucleosomes. The way in which eukaryotes compact and arrange their chromatin also helps regulate gene expression.
