This is a little technical but not hard to understand. I think the question has to do with the pairing of DNA bases. Adenine and Thymine are always paired and.

The purines on one strand of DNA form hydrogen bonds with the corresponding pyrimidines on the opposite strand of DNAand vice versa, to hold the two strands together.

Within DNA molecules, this is their most important function and is known as base pairing. Because hydrogen bonds are not as strong as covalent bonds, base pairings can easily be separated, allowing for replication and transcription.

Because purines always bind with pyrimidines — known as complementary pairing — the ratio of the two will always be constant within a DNA molecule.

In other words, one strand of DNA will always be an exact complement of the other as far as purines and pyrimidines go. This complementary pairing occurs because the respective sizes of the bases and because of the kinds of hydrogen bonds that are possible between them they pair more favorably with bases with which they can have the maximum amount of hydrogen bonds.

There are two main types of purine: One strategy that may help you remember this is to think of pyrimidines like pyramids that have sharp and pointy tops.

Which purines pair with which pyrimidines is always constant, as is the number of hydrogen bonds between them: C with three hydrogen bonds One way to remember which bases go together is to look at the shapes of the letters themselves. The letters made up of only straight lines A and T are paired with each other, while the letters that are made up of curves G and C also go together.

Can you tell us how nucleotide structure pertains to the case at hand? You see, you need to understand the chemistry behind DNA to fully appreciate the importance and function of the molecule.

What is true about the relationship of Adenine and Thymine? - lifeder English

The phosphate group and sugar are the same in every nucleotide, but there are four different nitrogenous bases: They are often abbreviated by the first letter of each nitrogenous base: They essentially function as a four-letter alphabet. Or, if I may make an analogy to the case at hand, the information in DNA is like a recipe in one of our poor victim's cookbooks.

For instance, reading a specific sequence of DNA tells one cell how to make hemoglobin protein to carry oxygen molecules throughout the body. On the other hand, another cell might read a different recipe, which tells it how to make insulin protein to control blood sugar levels. Oh, and 'reading', or transcribing, DNA is really an intriguing process.

Pyrimidines and Purines Miss Crimson: You were telling us about the nitrogenous bases. Cytosine bonds with guanine and adenine bonds with thymine Professor Pear: The bases can be categorized into two different groups. The single-ring nitrogenous bases, thymine and cytosine, are called pyrimidines, and the double-ring bases, adenine and guanine, are called purines.

Miss Crimson has a puzzled look.

I guess you might wonder how I can remember that, but it's really quite simple. And, by process of elimination, that means cytosine and thymine have to be pyrimidines.
