About video

Red blood cells gradually become filled with hemoglobin, their nuclei and other organelles are forced out. Cannot make new proteins and will be worn out within a few months. E) cannot make new proteins and will be worn out within a few months. A mature red blood cell lacks a nucleus thus it? Cannot make new proteins and will worn out within a few months asked in microbiology , cell biology (cytology). Red blood cells have no nucleus, because most of their bulk is made up of hemoglobin, a compound that carries gases, such as oxygen and carbon dioxide. In fact, about a third of a red blood cell is dedicated to hemoglobin alone, so no room remains for a nucleus or many of the structures that other cells have. The nucleus contains the dna and which can in turn produce protein. Knowing that it would lose its nucleus, hemoglobin is synthesized in the precursor stages of rbc. The rbcs need to pass through very narrow blood vessels,thus having a biconcave disk shaped structure. This shape is only possible when the nucleus and other organelles are absent.
