Double Stranded DNA is paired, with
Adenine paired with Thymine
Cytosine paired with Guanine
Then the percent Cytosine in one strand will be exactly the percent Guanine in the other strand.
And between the two strands, the percent Cytosine will be equal to the percent Guanine.
For a random distribution, the percent should be about 25% for each nucleotide, or 50% for the GC pair, and 50% for the AT pair.
However, DNA actually varies considerably from organism to organism.
Streptomyces coelicolor A3(2), has a GC content as high as 72%
Plasmodium falciparum has a GC content as low as 20%.
See Wikipedia link on GC Content.
37%. Adenosine pairs with thymidine while cytosine pairs with guanidine. Since 13% of the DNA is adenosine it means that 13% must be thymidine (since in a double stranded piece of DNA there are no bases without partners). 13% (adenine)+13% (thymidine) = 26%. 100% (total DNA)-26% (adenine and thymidine) = 74% (cytosine and guanidine). Half of the bases in the 74% are cytosine and half are guanidine (since there are no bases without partners). 74% divided by 2 = 37%. So the final make-up of the DNA is:
13% adenine
13% thymidine
37% guanidine
37% cytosine.
according to my text (genetics) states the % is 17 in a double-stranded DNA for cytosine.

Cytosine is a nitrogenous base of DNA.
cytosine (C).
Number of Guanine=Cytosine Thyamine=Adenine In a normal DNA
In the replication of DNA Thymine bonds with cytosine.
Guanine bonds to Cytosine in DNA through three hydrogen bonds. It also bonds to a Deoxyribose molecule in the backbone of the DNA molecule.
Cytosine is a nitrogenous base of DNA.

cytosine (C).
In DNA Guanine always pairs with Cytosine (C) cytosine (C) guanine (G) thymine (T) adenine (A)
Cytosine is the pyrimidine that bonds to the purine Guanine in both DNA and Rna.
Then you also have 13% cytosine, 37% guanine, and 37% adenine.
Cytosine can be various colors such as blue, purple and red. Cytosine in the DNA strand is the color purple.
20% because cytosine and guanine have equal amounts. Always
