However, gene expression is regulated by the expression of specific genes in specific cells and at a different time of developmental stages. Amylase is the enzyme that digests starch in humans. Amylase is secreted by salivary glands. So, the nuclei of these glands would have genetic information for the synthesis of amylase.
