If a segment of DNA has 20 adenine in its base composition what percent thymine is there?

The concentration of A must be equal to the concentration of T and the concentration of G must be equal to the concentration of C. This is because of the base pair rules that state that A pairs with T and G pairs with C. If you have a gene where [A] is 20%, this means that [T] also equals 20%. This puts the total concentration of A and T at 40%. Therefore the concentration of G and C is 100-40 which is 60%. This means that the concentrations of G and C are each 30%.

∙ 9y agoIf DNA has 20 percent of Adenine bases then the percentage of Thymine would also be 20 percent. This is because Adenine and Thymine pair together, so they will always have the same percentage.

∙ 13y agoit is 12%
becase G=C and A=T and so if C=38% also G=38% according to Chargaff's rule.
thus 38 +38 = 76% and % is out of 100 thus 76-100 to find the remaining which =to 24 and this is for both A and T , to find just for T -divide by 2 = 12% of Thymine!!

∙ 7y agoFor each adenine there is one thymine in a DNA segment. If there are 20 molecules of adenine in a given DNA segment, you have 20 molecules of thymine there in the same segment. There is one to one ratio between both of them.

What is adenine partners?
thymine
What forms hydrogen bonds with thymine?
adenine
The number of hydrogen bonds between adenine and thymine in DNA is?
A double hydrogen bond binds adenine and thymine
Because of specific base pairing if one side of the DNA molecule had the nucleotide sequence adenine-guanine-adenine-cytosine-thymine the other side would be?
thymine, cytosine, thymine, guanine, adenine *HINT* "A" goes with "T" always and "C" goes with "G" always
Can bind with guanine and adenine binds with?
guanine binds with cytosine in both RNA and DNA
According to chargaffs rules which nucleotide is always paired with adenine in a DNA molecule?
Chargaff's rules stated that the number of adenine units in a DNA segment were equal to the number of thymine units.
What are the 4 different bases in DNA?
A-Adenine C-Cytosine T-thymine G-guanine
What does Adenine A bond with?
Adenine bonds with thymine in DNA and uracil in RNA.
If you have 13 percent thymine in DNA what is then how much adenine do you have?
Then you also have 13% cytosine, 37% guanine, and 37% adenine.
In DNA adenine binds with?
thymine remember. adenine to thymine guanine to cytosine
Which nitrogen base bonds with adenine?
Thymine will always bond with adenine, and guanine will always bind with cytosine.
In DNA what does adenine always pair up with?
In DNA replication, adenine binds with thymine. In RNA, adenine binds with uracil.
Name the four nitrogen bases?
There are 4 nitrogenous bases found in DNA; Cytosine, Adenine, Guanine, and Thymine. Cytosine pairs with Guanine, and Thymine pairs with Adenine. *In RNA, Uracil replaces Thymine, therefore Adenine pairs with Uracil, in RNA.*
The amount of adenine will always equal what?
adenine In a DNA strand, the amount of Adenine equals the amount of Thymine, and the amount of Guanine equals the amount of Cytosine. So Adenine is your answer.
What does adenine match with?
In DNA, adenine pairs with thymine. In RNA, adenine pairs with uracil.
what are the four nucleotide base?
Adenine,Thymine,Guanine,and Cytosine
What is the sequence a-c-t-a-g-c-a-t-a?
Adenine-Cytosine-Thymine-Adenine-Guanine-Cytosine-Adenine-Thymine-Adenine
