Telomeres are short tandem repeats of nucleotides at the ends of chromosomes. Let's break this definition down a bit. Nucleotides are the building blocks of DNA, which is the carrier of genetic information. A tandem arrangement is when things are placed one behind another.
Definition: A board foot is a unit of measure used in the logging and lumber industry. It is a volume measurement that refers to the volume of a board.
Board feet are calculated by multiplying the surface area of the lumber (measured in square feet) by the thickness of the lumber (measured in inches). Examples: A board that's 1 thick, 12 wide and 24 long is: (1 foot wide) x (2 feet long) x (1 inch thick) = 2 board feet of lumber.
