X-Linked Dominant Traits

X-linked dominant traits affect both males and females. 

Although they often appear more frequently in females than in males.

Affected males must have affected mothers (unless the males possess a new mutation), and they pass the trait to all their daughters.

Affected daughters must have either an affected mother or an affected father.

X-linked dominant traits do not skip generations.

Retention factor (k) is simply the additional time that the analyte takes to elute from the column relative to an unretained or excluded analyte that does not interact with the stationary phase and which, by definition, has a k value of 0. Thus

Methylation interference assay Dimethyl sulphate (DMS) methylates purines on DNA strand. Methylate DNA prior to adding protein. Protein binding is prevented at methylated sites. After treatment and removal of protein of interest, treat with piperidine or NaOH which cuts strand at modified bases.
