SUMMARY
A restriction enzyme reads a DNA strand and cuts it after identifying a specific sequence of 6 nucleotide base pairs, AAGCCT. The probability of the enzyme correctly reading each base is 1/4, leading to a calculation of (1/4)^6 for the likelihood of this sequence occurring. The discussion highlights the need for clarification regarding the context of the DNA strand and whether the sequence can be read from both ends. Without additional information about the DNA strand's length or structure, determining the average length of a cut strand remains ambiguous.
