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.
RNA is assembled as a chain of nucleotides, that is usually  single-stranded. In eukaryotic cells, it can be found in the  nucleus and cytoplasm. Edit. Share to: Lsilvstew. 2,538 Contributions. Answered Most Recently. In Genetics.
DNA is found in the nucleus of cells (the N of DNA) associated with chromosomes. The genes, segments of DNA, are copied by enzymes to make RNA. RNA is then translated by a very large complex of enzymes into proteins. Some of these proteins are the very enzymes that make RNA and translate the RNA into proteins.
