Dna has unique properties that allow it to accurately retain genetic information, even after multiple rounds of replication. one
aspect of dna that allows it to accurately store genetic information is the base pairing from chargaff\'s first rule of the four nucleotide bases. if the c content of a dna molecule is 16%, what are the percentages of the remaining bases?
Accoring to the Chargaff's first rule of base pairing, each of the four nucleotide bases has its own complimentary match, that it always bids with. So, Adenine always bonds with Thymine and Cytosine always binds with Guanine. If you know the concentration of one base, in our case Cytosine, then you can easily calculate the percentage of other bases. Since Cytosine and Thymine are always paired, there is an equal amount of both of them -16%. So, 16% C + 16G = 32% of the whole DNA. This means that the other two base pairs A and T make up to 68% of the DNA. Half of the 68% is Adenine = 34% and half of it is Thymine- 34%. So, the percentages of base pairs in the DNA sequence are : 16% C 16% G 34 % A 34 % T
All organisms need energy to survive. This is supplied through photosynthesis or from consuming another being in the form of calories (Yes, calories are a form of energy).
That easy..............<span>21 one is your technical answer according to todays rules but scientist used to think it was only 20 so 20 would be your answer</span>
