Answer;
-Nuclei of gland cells.
Explanation;
-Enzymes are proteins that are manufactured in the ribosomes through the process of Translation. The process starts from the information contained in the DNA.
-First, the information in a DNA molecule is read and transcribed it into an intermediary molecule called messenger ribonucleic acid, or mRNA, which takes place in the nuclei. Next, the information contained in the mRNA molecule is translated into the "language" of amino acids, which are the building blocks of proteins, a process of translation which takes place in the cytoplasm in organelles called ribosomes.
