Question

which answer best explains how certain patterns of histone acetylation or dna methylation could influence whether a cell became a muscle cell or a brain cell?

Answer 1

Cells have unique characteristics wherein each develop a specific function determined by the activation of certain DNA sequences to generate this specific cell into its supposed design, this is why cell specialization exists. 

Hence, these cells can be directly identified with their morphological structures and the DNA sequences they posses.
