Primer design can be accessed in two ways:
Toolbox | Molecular Biology Tools () | Primers and Probes ()| Design Primers () | OK
or right-click sequence in Navigation Area | Show | Primer Designer ()
In the primer view (see figure 19.1), the basic options for viewing the template sequence are the same as for the standard sequence view (see View sequences for an explanation of these options). This means that annotations such as known SNPs or exons can be displayed on the template sequence to guide the choice of primer regions. In addition, traces in sequencing reads can be shown along with the structure to guide the re-sequencing of poorly resolved regions.
