What are the four bases of making up the rungs of the DNA ladder?
thymines, guanines, adenines, and cytosines
If there are 45 cytosines and 55 thymines how many guanines are there?
Given that DNA base pairing rules state that cytosine pairs with guanine and adenine pairs with thymine, for every cytosine there must be one guanine. Therefore, if there are 45 cytosines, there must also be 45 guanines.
Assume 100 bair pair DNA double helix contains 45 cytosines. how many adenines are ther?
Since DNA base pairs always have an equal amount of adenine and thymine, if there are 45 cytosines, there would also be 45 guanines. Therefore, the number of adenines would be equal to the number of thymines, making it 100 - 45 - 45 = 10 adenines.

What does chargoff's rule state?
Chargaff found that a peculiar regularity existed in the ratios of nucleotide bases. In the DNA of each species he studied, the number of adenines approximately equaled the number of thymine, and the number of guanines approximately equaled the number of cytosine. Essentially, A=T and C=G.
How are nucleotides joined together within a single DNA strand?
I just did this paper in Biology, the answer is Hydrogen bonds! :)
How did Poison Gas work?
It depends on the type of gas used, mustard gas was one of the most common types and this attached an alkyle group to guanine nucleotides in DNA. if these guanines were in genes then transcription stopped and replication of the DNA was stopped (or went seriously wrong) this normal lead to apoptosis (programed cell death) but depending on what genes were mutated and the type of cell attacked then it could cause cancer.
How did double helix structure match Chargaff's observations?
Chargaff observed that the number of Guanine units in a section/piece of DNA was the same as the number of Cysteine units and that the number of Thymine units equaled the number of Adenine units. This matched the double helix structure because Cysteine pairs with Guanine, and Thymine pairs with Adenine - meaning that Chargaff was right in that there must be an equal number of Cysteines and Guanines as well as equal Thymines and Adenines.
