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.
Best Answer: In organisms: DNA is double stranded. RNA is single stranded (though sometimes folded back on itself, as in tRNA). DNA is found in the nucleus (in eukaryotes) or free-floating in the cytoplasm (in prokaryotes), RNA is found pretty much anywhere, depending on the type of RNA. In viruses: DNA can be double or single stranded.
