What group does Cytosine and Thymine belong to?
They belong to the pyrimidine group.
Why are adenine and guanine longer than thymine and cytosine?
Yes. Adenine and guanine compose the nucleotide group known as purines. These are two ring structures and thus, the molecules are larger. Cytosine and thymine are pyrmadines and are only composed of one ring.
How is the hydrogen bond formed between purine and pyrimidine?
In the case of adenine bonding to thymine, the NH group of the thymine bonds with the N of the adenine, and the double-bonded oxygen on the thymine bonds with the NH2 group on the adenine. (thymine)N - H - N(adenine) and (thymine)=O - H - NH(adenine) In the case of guanine bonding to cytosine, the double-bonded O group of the cytosine bonds with the NH2 of the guanine, the N on the cytosine bonds with the NH group on the guanine, finally, the NH2 on the cytosine bonds with the double-bonded O on the guanine. (cytosine)=O - H - NH(guanine) and (cytosine)N - H - N(guanine) finally (cytosine)NH - H - O=(guanine) In summary, there are two H bonds between an adenine and a thymine. There are three H bonds between a cytosine and guanine.
What are the 4 parts of a DNA molecule?
The four bases of DNA are Adenine, Thymine, Cytosine, and Glucosis.
What compounds are the building blocks od DNA macromolecules?
A deoxyribose sugar backbone. A phosphate group backbone. Four different nitrogenous bases. ( adenine, thymine, guanine and cytosine )
What are found in a DNA nucleotide?
In a DNA nucleotide, the following are found:A nitrogen base, either adenine, guanine, cytosine, or thyminedeoxyribosephosphate group
What are the three pyrimidine bases?
There are 2 groups of nitrogen bases. These are Pyrimidine and Purine. In the Purine group, there are Adenine and Guanine, In the Pyrimidine group, there are Cytosine, Thymine(replaced by Uracil in RNA).
What group does Cytosine and Thymine belong to?
They belong to the pyrimidine group.
Why are adenine and guanine longer than thymine and cytosine?
Yes. Adenine and guanine compose the nucleotide group known as purines. These are two ring structures and thus, the molecules are larger. Cytosine and thymine are pyrmadines and are only composed of one ring.
What is a necleotide?
any of a group of molecules that, when linked together, form the building blocks of DNA or RNA: composed of a phosphate group, the bases adenine, cytosine, guanine, and thymine, and a pentose sugar, in RNA the thymine base being replaced by uracil.
What is the nitrogenous base belonging to the pyrimidine group?
Uracil, Thymine, and Cytosine
What are the rungs steps of a DNA molecule made of?
The 'steps' or 'rungs' of the DNA 'ladder' are complimentary pairs of bases bonded by hydrogen bonds. The bases are Adenine, Thymine, Cytosine and Guanine. Adenine always bonds to Thymine and Cytosine always bonds to Guanine.
Nitrogeneous base belonging to the pyrimidine group?
A pyrimidine group consists of only three nitrogenous bases: Uracil, Thymine, and Cytosine. All three are nitrogenous bases, so all three are the answer.
How is the hydrogen bond formed between purine and pyrimidine?
In the case of adenine bonding to thymine, the NH group of the thymine bonds with the N of the adenine, and the double-bonded oxygen on the thymine bonds with the NH2 group on the adenine. (thymine)N - H - N(adenine) and (thymine)=O - H - NH(adenine) In the case of guanine bonding to cytosine, the double-bonded O group of the cytosine bonds with the NH2 of the guanine, the N on the cytosine bonds with the NH group on the guanine, finally, the NH2 on the cytosine bonds with the double-bonded O on the guanine. (cytosine)=O - H - NH(guanine) and (cytosine)N - H - N(guanine) finally (cytosine)NH - H - O=(guanine) In summary, there are two H bonds between an adenine and a thymine. There are three H bonds between a cytosine and guanine.
What are the 4 parts of a DNA molecule?
The four bases of DNA are Adenine, Thymine, Cytosine, and Glucosis.
Which nuclotide pair bonds would be found in an DNA molecule?
The two different nucleotide pair bonds found in DNA are guanine-cytosine and adenine-thymine.
What 2 bases that belongs to the pyrimidines group?
The two Purines are: Adenine and Guanine (A and G) The two Pyrimidines are: Cytosine and Thymine (C and T)
