... Now that we have isolated good quality genomic DNA from our GAL4 enhancer trap lines, we can perform inverse PCR to identify the locations of the pGawB inserts. We will begin by digesting a portion of our genomic DNA with a restriction enzyme that cuts frequently, HpaII. Recombinant DNA technology w ...

... The alternate forms of a given STR correspond with different alleles. Most STRs occur in gene introns (non-coding regions of DNA), so the variation in the number of repeats does not usually affect gene function, but we can use STRs to differentiate between different alleles. Because pieces of DNA th ...

DNA supercoil



DNA supercoiling refers to the over- or under-winding of a DNA strand, and is an expression of the strain on that strand. Supercoiling is important in a number of biological processes, such as compacting DNA. Additionally, certain enzymes such as topoisomerases are able to change DNA topology to facilitate functions such as DNA replication or transcription. Mathematical expressions are used to describe supercoiling by comparing different coiled states to relaxed B-form DNA.As a general rule, the DNA of most organisms is negatively supercoiled.
