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.
It carries this information from DNA, which is housed inside the cell nucleus, to the ribosomes. These can be found in the cytoplasm and are the 'factories' which make the proteins. Inside the nucleus RNA transcribes the genetic information by producing a complimentary nucleic acid strand-a copy of a DNA sequence. When it reaches the ribosomes the information is translated to produce a protein.
