1B) (Matson 1986). Polarity is ascertained by identifying the duplex region that is denatured by the helicase. For helicases involved in DNA replication, the polarity of the reaction is strongly indicative of helicase placement on the leading (a 3 ' -5 'polarity) or lagging (a 5 +3 'polarity) strand.NA HELICASE ASSAYS DNA helicases are often first detected by a DNA-dependent or DNA-stimulated NTPase activity. Verification of DNA helicase activity is then accomplished using an assay that reveals the conversion of double-stranded DNA (dsDNA) into two single strands.
1. typical enlistment is 4 years, however during Vietnam 3 year enlistments were allowed. 2.
