How do I determine the amount of dna in an agarose gel? On the first run the band is visible above the 2 log ladder it is not in line with any of the ladder bands. On the second run the bands are in the middle of the 2 log ladder at about 23-124ng and 0.6-0.5kb. Any help is greatly appreciated.

I just noticed I have been putting undiluted coolant in my car for over 6 months now and I want to know will a simple drain of the current coolant in my radiator be enough or do I need to flush my coolant system (pipes)?

Thanks in advance

is the heat produced in a car affected by undiluted coolant? Or coolant with the wrong mix of coolant and water?

My car heat went out and it will cost too much to get it fix so I plan to trade it in in the summer. I just purchase a portable heater that goes into the cigarette lighter of the car for my windshield. Question is, is there any heater I can buy and charge at home then take to my car for heat? Live in New Jersey and winter is harsh.

Thanks in advance.

I have been using the autozone for all cars antifreeze and i don't think it is the right one because I had my systems flush by Nissan for water build up. The fluid nissan put in is green. I went to Napa before and they recommended one for Asian cars only. Should mention I live in jersey and winter (which is coming) is brutal over here.

I recently had my systems flush by Nissan they claim I had too much water within my car

If I have something like this (for a lack of a more complex example) c-c-c-c how do I know which one is C1? Where do I start from? If you can explain it in a ring structure as well I would appreciate it, thanks in advance.

Robinho(City), Torres, Da, Shevchenko to name a few, are players that made a great start after their transfers but went on to play bad midway through the season some started earlier.

Is Ozil going to make the list?

Let's face it with the way Real fans talked about this player and how he started I thought he was magical but recently it's been average or bad. Should Wenger consider resting him? He been known to have stamina issues even in la liga, maybe longer breaks might restore some magic.
