What are the 4 bases that makeup DNA?
There are four nucleotides, or bases, in DNA: adenine (A), cytosine (C), guanine (G), and thymine (T).
When bonded together chemically a deoxyribose sugar a phosphate group and an adenine molecule make up?
The components of DNA A nucleotide is made up of a sugar (deoxyribose), a phosphate group, and one of four nitrogenous bases: adenine (A), thymine (T), guanine (G) or cytosine (C). C and T bases, which have just one ring, are called pyrimidines, while A and G bases, which have two rings, are called purines.
What are 3 groups make up nucleotides?
Nucleotides contain three characteristic components: a nitrogenous base, a pentose, and one or more phosphate groups. The nitrogenous bases are derivatives of two parent heterocyclic compounds, purine and pyrimidine. The major pyrimidine bases are cytosine, thymine, and uracil.
What part of DNA does phosphate and deoxyribose make up?
backbone
The backbone of DNA consists of a phosphate group and a deoxyribose. These two components are therefore connected by a phosphodiester bond. The nucleotides are not included in the backbone.
Is deoxyribose in DNA or RNA?
DNA contains deoxyribose as the sugar component and RNA contains the sugar ribose.
What does cytosine pair with?
​Base Pair. The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.
Why does DNA have deoxyribose instead of ribose?
That’s why Ribose is choosed for RNA molecule. Now coming to DNA, due to reactivity of 2′-OH of the Ribose, RNA used to be unstable. So during evolution hydroxyl group is replaced by less reactive -H. So Ribose became deoxyribose and hence the DNA.
Which of the following does cytosine pair with?
guanine
Adenine always bonds with thymine, and cytosine always bonds with guanine.
Is deoxyribose a nucleotide?
​Nucleotide A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base. The bases used in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T).
What chemicals make up rungs?
nitrogen bases
The rungs of the ladder are pairs of 4 types of nitrogen bases. Two of the bases are purines- adenine and guanine. The pyrimidines are thymine and cytosine.
What is the purpose of phosphorus in a DNA strand?
For starters, phosphorus is an important structural element in DNA and RNA. Both of these genetic molecules have a sugar-phosphate backbone. The phosphate (PO4) works as a kind of “super glue,” since it has three oxygen atoms that will carry charges in solution.
What is deoxyribose used for?
Deoxyribose is a pentose sugar important in the formation of DNA, or deoxyribonucleic acid. Deoxyribose is a key building block of DNA. Its chemical structure allows for the replication of cells in DNA’s double helix configuration.
