The Hustle Inside a Cell’s Nucleus

The nucleus is a place of great activity - DNA strands being wrapped and unwrapped around the histone complexes; RNA polymerases and transcription factors dutifully transcribing genes to make mRNA; mRNA diligently being processed and transported outside the nucleus, while all along enzymes constantly patrol the processes. The nucleus really is a jungle of busy, hustling biomolecules, and here I represent a minuscule of what really goes on in there.
