In what cell types would you expect lactase gene expression

At any types. Different composite of multiple transcription procurator such as activators and repressors regulate the same gene in dissimilar types of cell. This is why the lactase gene is on in a small intestinal cell but off in a skin cell.

The main role of dna in the  cell is the long-term storage of information. it is often compared to a blueprint, since it contains the instructions to construct other components of the  cell, such as  proteins  and rna molecules.the main function of rna is to carry information of amino acid sequence from the genes to where  proteins  are assembled on  ribosomes  in the  cytoplasm. mark brainliest, my work is good.
