These are facultative genes which are active when needed, unlike constitutive genes which are expressed continually. Therefore, <u>t</u></span><span><u>o become specialized, cells need to control the production of proteins coded for in their DNA. </u>DNA segments, however, remain in cell and are not destroyed.
