Figure 6.

The AH36 interval from an rfk-1 mutant contains seven point mutations. (A) The 1481-bp sequence of AH36^Sk-2 is shown. A region containing 7.17 repeats of a 46–48-bp sequence is highlighted with red font and blue font. The colors alternate with each iteration of the repeated sequence. The sequence of AH36³²¹¹ contains seven G-to-A transition mutations. The position of each mutation is marked by a white character on a black background with the nonmutated base shown. The mutations in AH36³²¹¹ are (from left to right): G27904A, G27945A, G27972A, G28052A, G28104A, G28300A, and G28326A. The putative rfk-1 start codon is depicted with white characters on a green background. (B) Alignment of the repetitive sequences highlighted in (A).
