Extracted text: HDL-R: HDLS carry cholesterol to the liver for elimination. Liver cells respond to estrogen to express a protein receptor for HDLS coded by the HDL-R gene (HDL-R gene contains an estrogen response element.) PFK: codes for an enzyme called phosphofructokinase that is used in the first steps of breaking down glucose for energy in all cells. (Gene has no estrogen response element.) CD3: codes for a cell surface protein produced by immune B cells (Gene has no estrogen response element) Which of the following describes differences in the HDL-R gene in liver & immune cells? O The immune cell has permanently altered the HDL-R gene so that it can no longer be transcribed. O The immune cell has removed the estrogen response element from the HDL-R gene so that it cannot be transcribed. No difference O Only the liver cell retains the HDL-R gene, the immune cell has lost it.
