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 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). Another kind of RNA is small nuclear RNA, or snRNA, which is involved in altering an RNA transcript. Proteins are one of the vital biomolecules of life.
