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?

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.
