Why does a Cytosine-Adenine rich strand degrade?

A Cytosine-Adenine rich strand may degrade due to several reasons. One possibility is the hydrolysis of the phosphodiester bonds in the DNA backbone, which can lead to strand breakage. Additionally, certain environmental factors or enzymatic activities may cause the destabilization of the DNA structure, making it more susceptible to degradation. Finally, the presence of specific damaging agents, such as radiation or reactive oxygen species, can also contribute to the degradation of a Cytosine-Adenine rich DNA strand.


The nitrogen base that pairs with guanine?

In nucleic acids, the base that pairs with guanine is cytosine.


Is wheat and lentils carbohydrate-rich foods?

Yes!


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

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 is the uses of cytosine?

cytosine pairs with guanine to help make up DNA.
