This is being provided as a MS-Word file. Please type your responses to the questions below. Often a few words or a single sentence is sufficient for full credit. Please do not use more than three sentences in any response.
1. Why are G – C hydrogen bonds in DNA harder to break than A – T hydrogen bonds? (10 points)
-The main reason why GC base pairs are much stronger than AT base pairs is because of the number of Hydrogen bonds that contributes to their stability. As a rule, the more Hydrogen bonds, the stronger. And thus, GC bonds which have 3 H+ bonds are more stronger than AT bonds which only have 2 H+.
2. Does ‘euchromatin’ contain more genes than ‘heterochromatin’ (yes or no)? (10 points)
-No, euchromatin contains less DNA than heterochromatin
3. Is the human genome made up of more ‘euchromatin’ or ‘heterochromatin’? (10 points)
-The human genome is mainly made up of euchromatin
4. What is the approximate number of genes in the human genome? (10 points)...
