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.

DNA and RNA are nucleic acids found in the cells of living organisms. DNA is a two-stranded molecule consisting of a deoxyribose sugar, while RNA is a single-stranded molecule with ribose as its sugar component. There are three primary types of RNA: messenger RNA (mRNA), ribosomal RNA (rRNA) and transfer RNA (tRNA).
