What is the primary difference between euchromatin and heterochromatin?

A scientist observes a gene that is not being expressed. Upon analysis, they find that the histones associated with this gene are heavily methylated. What is the likely effect of this methylation on the chromatin structure?

What role do chromatin remodeling complexes play in gene expression?

How can epigenetic inheritance affect offspring?

Why are histone proteins crucial for DNA packaging in the nucleus?

What is the position effect in relation to gene expression?

What is cell memory in the context of non-genetic inheritance?
