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. The 3rd Marine Division was reactivated for Korea, and in 1956 moved to Okinawa as the cease fire there looked like it would hold. Air Bases remained active in Okinawa during the entire postwar and Cold War era to date.
At least 90 days of active duty service during WWI, WWII, Korean War, or the Vietnam War (09/16/40 to 07/25/47, 06/27/50 to 01/31/55, and 08/05/64 to 05/07/75). The 90 days does not have to be continuous. If you served less than 90 days, you may be eligible if discharged for a service-connected disability. For active duty service prior to 09/07/80 (enlisted) and 10/16/81 (officer) -- other than the dates listed above, you must have served 181 days of continuous active duty to qualify for a home loan guarantee.
