Measuring the number of cytosines and thymines in a small strand of DNA There are 45 cytosines and 55 thymines How many guanines are there in the srand how many adenines are there?
Cytosine always pairs up with guanine, and adenine always pairs with thymine. So, in your strand, there are 45 guanines and 55 thymines ...
Assume 100 bair pair DNA double helix contains 45 cytosines. how many adenines are ther?
55. 45 cytosines would mean there must also be 45 guanines. This leaves room for 55 base pairs of adenine and thymine. ...

What are the rungs of the DNA ladder made of?
The rungs of the ladder are pairs of 4 types of nitrogen bases (thymines, adenines, guanines, cytosines). --- The pairs are guanine and cytosine (G-C), or adenine and thymine (A-T). The rungs of the dna ladder are made of alternating sugars and phosophate groups. ...

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 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. ...

Can bacteria produce DNA?
Yes! bacteria can produce DNA as it also have genetic material in the form of DNA (plasmids) so as many time bacterial cell divide it produce DNA and intrestingly bacteria are used in many biotechnical process in which forigen DNA is incooperated in bacterial DNA for the production which then is isolated from the bacterial DNA. ...
