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.
Lineal feet, same as linear feet, means feet in a straight line. You'll need to just multiply the linear feet by the width of the board to get square feet. If you have 10 linear feet of wood, and the wood is 1 foot wide, you have 10 X 1 = 10 square feet of wood. Okay, I'm a bit confused. I have a porch that is 21 ft. by 10 ft.
