Simple Sequence DNAs are known to be located in which areas of the chromosome - found in centromere and some in telomere; interacts with the kinetochore Simple Sequence DNA - constitutes about 6% of the human genome, also called satellite DNA, concentrated near the centromere, backward slippage is used, number of repeats are vastly different, simple sequence is mobile; doesn't code for anything Gene - a unit of heredity that is transferred from a parent to offspring and is held to determin...
