Question 1200864: DNA molecules include the base units adenine, thymine, cytosine, and guanine (A, T, C, and G). The sequence of base units along a strand of DNA encodes genetic information. In how many different sequences can A, T, C, and G be arranged along a short strand of DNA that has only 8 base units?

DNA molecules include the base units adenine, thymine, cytosine, and guanine (A, T, C, and G).
The sequence of base units along a strand of DNA encodes genetic information.
In how many different sequences can A, T, C, and G be arranged along a short strand of DNA that has only 8 base units?
~~~~~~~~~~~~~~~~~~~~~~
In  = 65536 different ways. ANSWER
Any of 4 base units can be in the 1-st position.
Any of 4 base units can be in the 2-nd position, independently.
Any of 4 base units can be in the 3-rd position, independently.
. . . and so on, if there are no other restrictions . . .
It gives the answer above.
Solved.
