How do adenine and thymine and cytosine and guanine differ?

thymine and cytosine are single-ring structures, whereas adenine and guanine are double-ring structures.

What bases do adenine and guanine have?

adenine and guanine are double ringed bases, that bond with thymine and cytosine (mono ringed bases). adenine bonds with thymine (double connection, whereas guanine bonds with cytosine (triple connection)

What are the rungs made of in a double helix DNA?

The 'rungs' in DNA consist of adenine, thymine, cytosine, and guanine. Adenine and thymine bond, and cytosine and guanine bond.

Which nucleotide is found in the DNA?

Adenine, guanine, cytosine and thymine. Adenine and guanine are double ringed purines and cytosine and thymine are pyrimidines of a single carbon/nitrogen ring.

What is the structure and bases of DNA?

dna is deoxyribonucleic acid, and the bases are thymine, guanine, cytosine, and adenine. adenine pairs with thymine, cytosine pairs with guanine. the structure is a double helix

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 nitrogen bases in a DNA double helix?

adenine, thymine, cytosine and guanine

Structure of DNA and RNA?

DNA: - double helix - deoxyribose - Thymine, Guanine, Cytosine, and Adenine RNA: - single strand - ribose - Uracil, Guanine, Cytosine, and Adenine

Why are guanine and cytosine and they and adenine useful in the DNA molecules?

Guanine is a purine and Cytosine is a pyrimidine. They are nucleotides that pair together. The two are useful in DNA molecules because they pair together, along with Adenine and Thymine, which build a double helix. Guanine, Adenine, Thymine, and Cytosine are all nitrogenous bases.

Is there double and triple bonds present in DNA?

DNA is made up of double and triple bonds. If you remember the nitrogenous basis i.e. adenine. guanine, cytosine and thymine, where adenine pairs with thymine by double bond and guanine pairs with cytosine with triple bonds.

What does guanine pair on DNA?

Guanine pairs with Cytosine on the human DNA double helix. Adenine pairs with Thymine.

How are the bases paired within the DNA double helix -?

G to C A to T Guanine pairs with cytosine, and adenine with thymine, due to the hydrogen bonding in two locations between adenine and thymine, and three in guanine and cytosine.

How are the two strands of the double helix held together?

by the sugars - adenine , thymine , cytosine, and guanine

What are the four pairs of DNA bases that form the double helix?

Adenine, Thymine, Cytosine and Guanine

Are adenine and guanine larger molecules than cytosine and thymine?

yes they are. Becuase they are double ring sugars. Howver Cytosine and Thymine are single rign sugars.

Which bases pair with each other in the DNA double helix?

The bases are: thymine, guanine, cytosine, and adenine.

What is the base pairing rule that applies in double stranded DNA?

Adenine is paired with thymine.Cytosine is paired with guanine.

Why Guanine and cytosine have triple bond in between and Adenine and Thymine have double bond in between?

Guanine has an extra hydrogen in it's structure that allows it to form an extra hydrogen bond with thymine

What are nitrogenous bases?

the bases that hold the shape of a double helix-5 kinds(Uracil, Thymine, Cytosine. Guanine, Adenine)

DNA what are doulbe and triple bonds?

Adenine bonds to thymine (double bond) Cytosine binds to guanine (triple bond)

What are the base pair rules for DNA?

Pair rules also "nitrogenous bases" are: Adenine pairs with thymine Guanine pairs with cytosine Thymine pairs with adenine Cytosine pairs with guanine In case you are wondering when transcription occurs the top of the deoxyribose double-helix backbone can have thymine. Though on the RNA strand it cannot have thymine, but is replaced with Uracil.

What four nitrogenous bases are found in DNA and how do they bond together in pairs?

nitrogenous bases are nitrogen containing organic compounds that has the chemical properties of a base In dna four types of nitrogenous bases are : Adenine,guanine ,cytosine,thymine Adenine and guanine are known as purine bases and cytosine and thymine known as pyrimidine bases Adenine always pairs with thymine by double hydrogen bond And cytosine always pairs with guanine by triple hydrogen bond

Describe the structure of the DNA?

DNA means dioxyribo nucleic acid. DNA is in a double helix with bars of chemicals running between. These chemicals are adenine, guanine, cytosine, and thymine. In it, the adenine forms bars with the thymine, and the cytosine pairs with the guanine. Lining the edges of the DNA are sugar and phosphate.

In RNA which component is different from DNA?

DNA is double stranded and uses four bases: Adenine Thymine, Guanine, and Cytosine RNA is single stranded and uses four bases as well with one difference: Adenine Uracil, Guanine, and Cytosine RNA does not have Thymine, it uses Uracil instead.

How do base pairing rules relate to the structure of DNA?

Well the base paring rules are the rules that state that cytosine pairs with guanine and adenine those pair with thymine in DNA, and also that adenine pairs with uracil in RNA. On the other hand, the DNA structure is the crosspieces and combinations of four chemicals called nucleotides: adenine, cytosine, thymine, and guanine. Adenine only links with thymine and cytosine only links with guanine. The structure is called a double helix, and is common to all DNA.
