Time-saving video on the circulatory system. The circulatory system transports nutrients and blood cells to and from cells throughout the body. The circulatory systems includes veins, arteries and capillaries.
Ribosomal RNA (rRNA) is found in the cell's ribosomes, the specialized structures that are the sites of protein synthesis). Transfer RNA (tRNA) found in the cytoplasm which carries amino acids to the ribosomes for incorporation into a protein.
The nitrogen containing base that is found only in RNA is uracil. What are the names of the nucleotides found in DNA and RNA?   In DNA, the four bases are: adenine, guanine, thymine, and cytosine. Each base is attached is attached to a sugar (deoxyribose) to form a nucleoside. Respectively, tâ¦hese are: adenosine, guanosine, thymidine, and cytidine.
