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.
What else can I help you with?
When DNA is extracted from E coli cells and analyzed for base composition it is found that 42 percent of the bases are cytosine this means that there is also 42 percent of which base?
If 42 percent of the bases in E. coli DNA are cytosine, then 42 percent will also be guanine. This is because cytosine always pairs with guanine through three hydrogen bonds in DNA double helix structure.
What in DNA always forms bonds with guanine?
cytosine (C).
What nucleotide bonds with guanine?
Guanine bonds to Cytosine in DNA through three hydrogen bonds. It also bonds to a Deoxyribose molecule in the backbone of the DNA molecule.
Is cytosine not a nucleotide of DNA?
Cytosine is a nitrogenous base that is a component of DNA, but on its own, it is not a nucleotide. In DNA, cytosine pairs with guanine through hydrogen bonding to form a complementary base pair. Nucleotides are composed of a nitrogenous base, a sugar, and a phosphate group.
Are there different numbers of cytosine and guanine in the same DNA?
Number of Guanine=Cytosine Thyamine=Adenine In a normal DNA
If DNA were 40 percent cytosine what would be percent of guanine?
20% because cytosine and guanine have equal amounts. Always

A double-stranded DNA molecule contains 30 percent guanine What is the percent cytosine in this molecule Where is the promoter region?
30 percent
What in DNA always forms bonds with guanine?
cytosine (C).
Pyrimidine base found in DNA and RNA?
Cytosine is the pyrimidine that bonds to the purine Guanine in both DNA and Rna.
Guanine is a complementary base for which of these DNA nucleotides?
Guanine is a complementary base for cytosine in DNA.
In dna guanine pairs with?
In DNA Guanine always pairs with Cytosine (C) cytosine (C) guanine (G) thymine (T) adenine (A)
Which nitrogenous base pairs with cytosine in DNA and RNA?
In both DNA and RNA, cytosine pairs with guanine.
What nucleotide bonds with guanine?
Guanine bonds to Cytosine in DNA through three hydrogen bonds. It also bonds to a Deoxyribose molecule in the backbone of the DNA molecule.

Are there different numbers of cytosine and guanine in the same DNA?
Number of Guanine=Cytosine Thyamine=Adenine In a normal DNA
What are bases in DNA and RNA?
DNA Adenine with Thymine, Guanine with Cytosine RNA Adenine with Uracil, Guanine with Cytosine
