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...

Tightly linked together at a centromere. e. Made only of DNA - Answer-d. Tightly linked together at a centromere. Looking into your microscope, you spot an unusual cell. Instead of the typical rounded cell shape, the cell has a very narrow middle separating two bulging ends. It sort of looks like the number 8! Then you re...
