WebDNA structure and function. DNA is the information molecule. It stores instructions for making other large molecules, called proteins. These instructions are stored inside each of your cells, distributed among 46 long structures called chromosomes. These chromosomes are made up of thousands of shorter segments of DNA, called genes. WebThe endoplasmic reticulum. The endoplasmic reticulum ( ER) plays a key role in the modification of proteins and the synthesis of lipids. It consists of a network of membranous tubules and flattened sacs. The discs and tubules of the ER are hollow, and the space inside is called the lumen. WebThe severity of CF symptoms in CFTR proteins affected by gating mutations will be more severe than CFTR proteins affected by conduction mutations. This is because rather than completely blocking chloride from leaving the cell, the function of the protein channel is faulty, allowing less chloride to leave the cell less frequently. highcrest apartments mn
