Answer:
Chromatin is responsible for gene expression.
Explanation:
Chromatin is responsible for gene expression because chromatin contains DNA that has all information about genes. chromatin controls the gene in order to form encoded products. DNA in chromatin send information to the RNA to produce specific types of proteins that are needed by the organisms for its growth and development so in that way the genes can be expressed in the organism.

The enzyme that makes RNA knows where to start transcribing the DNA by knowing where to start transcribing at the promoter site. For example,<span> TATA Box in Eukaryotes. Hope this answers the question. Have a nice day. Feel free to ask more questions.</span>
