The predominant cells in blood are the red blood cells (RBC) which contains a protein called hemoglobin. Hemoglobin is the principal determinant of the color of blood. Arterial blood and capillary blood are bright red, as oxygen imparts a strong red color to the heme group.

1 RNA is found in both the nucleus and the cytoplasm. 2  RNA concentration correlates with protein production. 3  Cells that produce large amounts of protein have cytoplasmic dye-and radiation-absorbing regions indicative of the presence of nucleic acids.he single-celled alga Acetabularia played an important role in elucidating the site of protein synthesis. During part of its life cycle, Acetabularia takes on an unusual umbrella-like form, during which the cell 's nucleus is located completely within the boundaries of a spatially distinct foot called a rhizoid.
