Make a 50 ml agarose gel of 0.8% that is 0.5x tbe. the tbe (tris fw = 121.1, borate fw = 61.8, edta fw w = 372) stock is 10x. you have a 150x stock of buffer and you need 2.5 ml of 1x. how do you make this? you have a dna solution that is 21.3 mu g/mu_1 and you want 75 mu 1 that is 50 mu g/mu 1. how do you make this? make 350 ml of a solution that is 25 mm tris, 2.5 mm edta, and the ph is 8.0. tris is a base and the fw of tris is 121.1 and edta is 187. do not make a volume that exceeds 350

First up write the aim
then write the materials reqd.
then the procedure which you follow
then observation
then conclusion
then you can write lab safety rules or precautions(you can avoid if u want).
lemme' give an example
aim: to observe the double displacement reaction
materials reqd: bacl2 and na2so4, test tubes and a dropper
procedure:
1. take bacl2 in a test tube and na2so4 in the other.
2. then pour bacl2 into na2so4 solution.
3. observe
observation:
you will see that a white precipitate is formed called baso4. along with that common salt or nacl is formed.
the equation is
bacl2+na2so4=baso4+2nacl
conclusion:
a double displacement reaction is observed.
hope it
