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.
Nucleic acids are molecules made up of nucleotides that direct cellular activities such as cell division and protein synthesis. Each nucleotide is made up of a pentose sugar, a nitrogenous base, and a phosphate group. There are two types of nucleic acids: DNA and RNA. DNA carries the genetic blueprint of the cell and is passed on from parents to offspring (in the form of chromosomes). It has a double-helical structure with the two strands running in opposite directions, connected by hydrogen bonds, and complementary to each other.
