There is no consistent amount of guanine in everyone's DNA, but there is an equal amount of guanine and cytosine as well equal amounts of thymine and adenine.
thymines, guanines, adenines, and cytosines
purines
what are 4 bases that make up the rungs of the DNA ladder
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.
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.
I just did this paper in Biology, the answer is Hydrogen bonds! :)
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.
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.
The four bases of the DNA ladder are adenine (A), thymine (T), cytosine (C), and guanine (G). These bases pair up in a complementary way (A with T and C with G) to form the rungs of the DNA double helix.
There are 32 DNA bases in 8 DNA nucleotides.
There is only one kind of DNA
