Other endorsements included Wickes Furniture, Ames Hardware, Old Spice, and the American Cancer Society. On July 26, 2011, Old Spice launched a new campaign on YouTube in which Fabio challenges Isaiah Mustafa to try to replace him as the New Old Spice Guy. The online challenge was entitled Mano a Mano in el BaÃ±o (hand-to-hand in the bathroom). Mustafa emerged as the winner, though Fabio's Old Spice YouTube Channel received more than 9 million views in the week after its debut, rising to Number 4 on YouTube for the week.
The cell nucleus contains the majority of the cell's genetic material in the form of multiple linear DNA molecules organized into structures called chromosomes. Each human cell contains roughly two meters of DNA.
A second important type of RNA is transfer RNA (tRNA). Transfer RNA exists in the cell cytoplasm and carries amino acids to the ribosomes for protein synthesis. When protein synthesis is taking place, enzymes link tRNA molecules to amino acids in a highly specific manner. For example, tRNA molecule X will link only to amino acid X; tRNA molecule Y will link only to amino acid Y. The third form of RNA is messenger RNA (mRNA). In the nucleus, messenger RNA is constructed from DNAâs code of base pairs and carries the code into the cytoplasm or to the rough endoplasmic reticulum where protein synthesis takes place. Messenger RNA is synthesized in the nucleus using the DNA molecules.
