it is a molecule in cells that carries codes from the DNA in the nucleus to the sites of protein synthesis in the cytoplasm,the ribosomes.
Why does mRNA exists and what's its job?
Passive Transport moves ions from high concentration to low, using no metabolic energy.
Active Transport moves ions from low concentration to high, using metabolic energy in the form of ATP..
