FIG. 1. Single base error spectrum of human DNA Pol . The
407 template nucleotides within the single-strand gap of the
M13mp2 substrate DNA are shown as 5 lines of the template
sequence, with nucleotide +1 as the first transcribed nucleotide
of the LacZ -complementation
region. Base substitutions are indicated by letters below the
line of the target sequence. Deletion of a base is depicted by
an open triangle above the line of the sequence, whereas
addition of a base is indicated below the line of the sequence
by " " immediately above
the added base. The arrow indicates the direction of synthesis.
