times, or as 70 bp (where bp stands for base pairs) because it is 70 bp in length, including the flanking regions. A different allele of this same STR would have a different number of GATA repeat units but the same flanking regions. Flanking regions are important because knowing their sequences enables geneticists to isolate the STR usingFigure S2: Alignment of glucokinase gene sequences from diverse mammals, using mouse as the master sequence. A genomic sequence alignment was generated by MultiPipMaker (24,25). The sequence is numbered (in kilobases, k) from the 5′ end of the liver-specific transcript, with 5′ flanking sequence numbered backwards.tides, from which sequences could be deduced. For DNA sequences we have used the enzyme DNA polymerase, which copies single-stranded DNA as shown in Fig. 1. The enzyme requires a primer, which is a single-stranded oligonucleotide having a sequence that is comple-mentary to, and therefore able to hybridize with, a region on the DNA being

Here are some guidelines for designing your PCR primers: Aim for the GC content to be between 40 and 60% with the 3’ of a primer ending in G or C to promote binding. This is known as a GC Clamp. The G and C bases have stronger hydrogen bonding and help with the stability of the primer. Be mindful not to have too many repeating G or C bases ...Analysing the flanking sequences surrounding genes of interest is often highly relevant to understanding the role of mobile genetic elements (MGEs) in horizontal gene transfer, particular for antimicrobial resistance genes.
