All Answers (8) 1  This is nice information from wikipedia visit. 2  I guess if you assume the DNA is at rest with an average rise of 3.4 A per base pair, then the length of chr1 would be 3.4A * 249*10^6, i.e. 847*10^6A, i.e. ~85 mm, or 8.5 cm.
Boiler sizing includes two things: 1  The heating and hot water capabilities of the boiler. 2  The physical size of your boiler and whether it will fit in the space you have it destined for.
Owning an actual double boiler is handy if you do a lot of cooking that requires it. If you only need one occasionally, you can accomplish the same effect by setting a metal mixing bowl over a saucepan of simmering water. Just make sure the bottom of the mixing bowl doesnât touch the surface of the water.
