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.
Calculating Board Feet. BOARD FEET: Board Feet is a measurement of lumber volume. A board foot is equal to 144 cubic inches of wood. Actually it's easy to calculate using the following formula: (Thickness x Width x Length) / 144 = Board Feet. Note: Lumber is specified by its rough size. This is why a 1x 4 board is actually 3/4 thick and a 2x 4 board is actually 1-1/2 thick. When you are figuring up board feet, keep in mind a waste factor.
