a) Find a nitrogen base. What carbon is the base attached to?
b) What two nitrogenous bases are held together by 2 hydrogen bonds?
c)What two nitrogenous bases are held together by 3 hydrogen bonds?
You will be building a double-stranded DNA molecule, representing a short (20 base) sequence that could be found in a chromosome. It will have a 3' --> 5' strand and a 5' --> 3' strand.
Use two full 12-base-pair DNA models.
a) Upload a photo of a model once the first 6 nucleotides have been inserted to base pair with the two parent strands.
b)Upload a photo of DNA polymerase I and Ligase in "action" removing the RNA primer nucleotides and making new phosphodiester bonds.
c)Upload a photo of the final two DNA strands, after Termination, identifying the parent and daughter strands of each.
Write down the 12 base-pairs (ex A-T or G-C) contained in the two models you will us from top to bottom below
