The table shows where different restriction endonucleases (restriction enzymes) cleave DNA. The abbreviation R represents the purines (adenine and guanine). The pyrimidines (cytosine, thymine, and uracil) are abbreviated as Y.

Ch 11.6: Direct Products of Groups The following questions work in the product space [Z7, +7] × [Z4, ×7]. 6 What is the identity element in this group? 7 Determine the powers (2, 2)$^2$, (2, 2)$^4$, (2, 2)$^8$, (2, 2)$^{16}$. Note: Use the fact that (2, 2)$^4$ = (2, 2)$^2$ × (2, 2)$^2$, and proceed similarly for the other powers. 8 Use your answers to the previous question to determine (2, 2)$^{21}$ and (2, 2)$^{22}$. Hint: (2, 2)$^{21}$ = (2, 2)$^{16+4+1}$, 9 Use your answer to the previous question to determine (2, 2)$^{-1}$.
