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.

The transcription of mRNA begins in the nucleus. The DNA is uncoiled and the nucleic acids with nitrogen bases adenine, thymine, guanine, and cytosine combine to form an incomâ¦plete mRNA. The current RNA contains exons (the coding region) and introns (non-informational regions).
