DNA stands for deoxyribose nucleic acid This chemical substance is present in the nucleus of all cells in all living organisms DNA controls all the chemical changes which take place in cells. Living Environment . Mr. Wiley. 144. Good Morning!. Do now:. Answer the following on your scrap paper.. Describe the role of the nucleus in the cell. Describe the role of the ribosome in the cell. Explain how the nucleus and the ribosome help to maintain homeostasis in the cell.. DNA from a few Angles. Cell: . Every cell contains a nucleus which is filled with the directions for cell function, DNA. . Chromosome. : . When DNA is tightly coiled and wound it becomes visible in the form of . “DNA is a helical structure” . with “two co-axial molecules.”. “period is 34 .
