Why guanine cytosine rich DNA is more difficult to denature than an adenine thymine rich DNA?

∙ 10y ago
Within the DNA model, adenine pairs with thymine and guanine pairs with cytosine (AT CG) and these nitrogenous bases are held together by hydrogen bonds, fairly strong bonds. However, adenine and thymine are linked by two hydrogen bonds between strands, whereas cytosine and guanine are linked by three hydrogen bonds. Therefore, if the DNA sample was rich in guanine and cytosine the two strands would be linked predominantly by three hydrogen bonds, thus, the two strands would be held together more. More heat would be required to break these three hydrogen bonds located through the DNA strand, as opposed to just two hydrogen bonds.

What are the RNA nitrogen bases?
Adenine, guanine, cytosine and uracil ( which stands in for thymine ).
The nitrogen base that pairs with guanine?
In nucleic acids, the base that pairs with guanine is cytosine.
What is the pairing arrangement of the nitrogen base?
the pairing is adanine with thymine and guanine with cytosine. the pairing is adanine with thymine and guanine with cytosine.
What bases are found in DNA?
Adenine, Thymine, Guanine, and Cytosine
What are the nitrogenous base pairing rule?
adenine bonds to thymine cytosine bonds to guanine. (In RNA adenine bonds to uracil)
What are the 4 different bases in DNA?
A-Adenine C-Cytosine T-thymine G-guanine
Can bind with guanine and adenine binds with?
guanine binds with cytosine in both RNA and DNA
What are four nitrogen bases on DNA?
The four nitrogenouse bases found in DNA are adenine, thymine, cytosine, and guanine. When they are paired up it's always adenine to thymine, guanine to cytosine, thymine to adenine, and cytosine to guanine. They can't be mismatched such as adenine to guanine or cytosine
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.*
What are the RNA nitrogen bases?
Adenine, guanine, cytosine and uracil ( which stands in for thymine ).
What are the 4 bases of the DNA ladder?
Adenine,Thymine,Guanine,and Cytosine. Adenine and thymine pair up and guanine and cytosine pair up.
The nitrogen base that pairs with guanine?
In nucleic acids, the base that pairs with guanine is cytosine.
What is the pairing arrangement of the nitrogen base?
the pairing is adanine with thymine and guanine with cytosine. the pairing is adanine with thymine and guanine with cytosine.
What are the four type of nitrogen bases?
Thymine Guanine Cytosine Adenine
What bases are found in DNA?
Adenine, Thymine, Guanine, and Cytosine
What are the nitrogenous base pairing rule?
adenine bonds to thymine cytosine bonds to guanine. (In RNA adenine bonds to uracil)
What nucleotide basis are present in equal amounts of DNA?
The nucleotide bases guanine and cytosine, and adenine and thymine are present in equal quantities in DNA. This is how scientists determined that guanine pairs with cytosine, and adenine pairs with thymine.
