I don't have a good stockpile of extra RFLP questions, so instead am giving you quite a few
(some quite challenging) from the book and "for credit", to give you lots of practice.
"For credit" problems are due Tuesday, May 27 by 8:00 am.
You can turn them in to the
drop box outside Sinsheimer or give them to me BEFORE class on Tues.
Spinobulbar muscular atrophy is a dominant disease due to expansion of a CAG repeat in the
gene encoding androgen receptor (AR).
Normal individuals have a small number of CAG
repeats, e.g. 11 repeats in their AR gene.
Affected individuals have an expanded number of
repeats, e.g. 64 repeats in one allele of the AR gene.
You want to use PCR to amplify the CAG-
containing region of AR, to estimate the number of repeats in individuals.
Show where in the
region you would want PCR primers to hybridize, and on the gel below the diagram show the
relative sizes of the PCR products that would be produced from a normal individual and from an
What size difference would you expect to see between the PCR products?
