Question:
The DNA molecule is a double helix consisting of two strands joined by bonds involving 4 substances called bases: adenine, cytosine, guanine, and thymine. Assume that these bases are uniformly distributed along an entire strand of a DNA molecule. A geneticist randomly selects 8 consecutive bases in a DNA molecule for study.
a) How many sequences of the 8 bases are possible?
b) What is the probability that the sequence consists of 6 guanine and 2 adenine bases?
c) What is the probability that the sequence does not consist of 4 cytosine and 4 thymine bases?
