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.
DNA-Double chain structure-contains deoxyribose sugar-bases are adenine, cytosine, guanine and thymine-DNA is found in the nucleus-there aren't different types of DNA.hart out RNA (nucleic acid). RNA-single chain structure-contains ribose sugar-bases are adenine, cytosine, guanine and uracil-RNA is found in the nucleus and cytoplasm-there are three different types of RNA-messenger RNA (mRNA); ribosomal RNA (rRNA); and transfer RNA (tRNA).
