Assume that the growing polypeptide chain of amino acids being produced represents an enzyme humans use to digest starch. the original blueprint for the production of this enzyme can be found, most specifically, in the a) salivary glands. b) nuclei of gland cells. c) ribosomes of gland cells. d) saliva of the human mouth.

B) nuclei of gland cells.

Explanation:

DNA carries the blueprint for the production of all the proteins including enzymes in human beings. Humans are eukaryotes and their DNA is present in the nucleus of their cells. All the cells that make the complex human body are derived from division in the zygote and therefore, are genetically identical and have the same DNA.

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.

The answer is B) Nuclei Of Gland Cells.

Explanation:

i think it would be b. tissue because an organ system is a group of organs that work together to perform one or more functions. each does a particular job in the body, and is made up of certain tissues.
