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.
1 rRNA is located in the cytoplasm of a cell, where ribosomes are found. 2  rRNA directs the translation of mRNA into proteins. 3  tRNA or Transfer RNA. 4  Like rRNA, tRNA is located in the cellular cytoplasm and is involved in protein synthesis. tRNA or Transfer RNA. 2  Like rRNA, tRNA is located in the cellular cytoplasm and is involved in protein synthesis. 3  Transfer RNA brings or transfers amino acids to the ribosome that correspond to each three-nucleotide codon of rRNA.
