What else can I help you with?
What group does Cytosine and Thymine belong to?
Cytosine and Thymine both belong to the group of nucleotide bases known as pyrimidines.
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 are the 4 parts of a DNA molecule?
The four bases of DNA are Adenine, Thymine, Cytosine, and Glucosis.
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 many smaller molecules that make up DNA?
The smaller molecules that make up DNA are nucleotides. Each nucleotide consists of a sugar molecule (deoxyribose), a phosphate group, and one of four nitrogenous bases: adenine (A), cytosine (C), guanine (G), or thymine (T).
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?
Cytosine and Thymine both belong to the group of nucleotide bases known as pyrimidines.
What 2 bases that belongs to the pyrimidines group?
I presume you are talking about the 4 heterocyclic bases in DNA. Two, cytosine and thymine, are based on pyrimidine and the other two, guanine and adenine, are based on purine.
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 is the nitrogenous base belonging to the pyrimidine group?
Uracil, Thymine, and Cytosine
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.
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.
What are the three molecules of a nucleotide?
The three molecules of a nucleotide are a phosphate group, a five-carbon sugar (ribose or deoxyribose), and a nitrogenous base (adenine, cytosine, guanine, thymine, or uracil). These components form the basic building blocks of nucleic acids like DNA and RNA.
What are the 4 nucleotide bases and which pair with which?
A nucleotide consists of three parts: * A Sugar (Deoxyribose) * A Phosphate Group * A Nitrogen-containing base Base Pairing Rules A&T (Adenine&Thymine) C&G (Cytosine&Guanine)
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.
What are the 4 parts of a DNA molecule?
The four bases of DNA are Adenine, Thymine, Cytosine, and Glucosis.
What are the molecules that make up DNA?
There are six molecules that make up DNA. These are: a five carbon sugar called deoxyribose, a phosphate group and four nitrogenous bases, which are thymine, guanine, adenine, thymine and cytosine.
