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.
RNA in eukaryotic cells (humans, plants, animals) is made inside the nucleus. After transcribing from DNA to RNA in the nucleus, pre-mRNA (messenger RNA) is processed (splicing, polyadenylation, capping) and then mRNA is transported out of the nucleus into the cytosol, where it is translated to protein by ribosomes.NA in eukaryotic cells (humans, plants, animals) is made inside the nucleus.
