What is cell differentiation?

The process by which unspecialized cells develop into distinct cell types with specific functions.

Regulates cell growth and metabolism, often implicated in cancer.

Mechanism: How do transcription factors influence chromatin structure?

They recruit co-activators or co-repressors that modify histones, altering chromatin accessibility.

What is a transcription factor's consensus sequence?

A specific DNA sequence recognized by a transcription factor for binding.
