What is the difference between a pentose and a nitrogenous base?
When a pentose is connected to a nitrogenous base, carbon atom numbering is distinguished with a prime (') notation, which differentiates these carbons from the atom numbering of the nitrogenous base.
How many amino acids are there in nitrogenous base molecules?
There are only 5 nitrogenous base molecules, yet there are over 20 amino acids which can be called for. By itself, a single base does not have enough information to specify any one of these. With two other base molecules, it can specify exactly which of the amino acids is called for.
What is an example of A nitrogenous base?
Nitrogenous base: A molecule that contains nitrogen and has the chemical properties of a base. The nitrogenous bases in DNA are adenine (A), guanine (G), thymine (T), and cytosine (C). The nitrogenous bases in RNA are the same, with one exception: adenine (A), guanine (G), uracil (U), and cytosine (C).
What are nitrogenous bases for kids?
nitrogenous bases—there are four of these: adenine (A), thymine (T), cytosine (C), guanine (G) carbon sugar molecules. phosphate molecules.
What does the nitrogenous base do?
In DNA and RNA, a nitrogenous base forms a bond with a 5-sided carbon sugar molecule, which forms a “backbone” for the entire molecule. A nitrogenous base plus this sugar backbone is known as a nucleotide, and forms the building blocks of DNA and RNA.
What does nitrogenous base mean biology?
or nitrogenous base a nitrogen-containing organic compound that has the chemical properties of a base, especially a pyrimidine or purine: Four nitrogen bases are present in a DNA molecule.
Where is the nitrogenous base?
The nitrogenous bases are in the interior of the DNA double helix, with the sugars and phosphate portions of each nucleotide forming the backbone of the molecule.
What are nitrogenous bases made of?
The nitrogenous bases are purines such as adenine (A) and guanine (G), or pyrimidines such as cytosine (C), thymine (T), and uracil (U). Figure 1. Each nucleotide is made up of a sugar (ribose for nucleotides in RNA, deoxyribose for nucleotides in DNA), a phosphate group, and a nitrogenous base.
How do you identify a nitrogen base?
The five-carbon sugar ring and the content of the nitrogenous base between DNA and RNA are slightly different from each other. Four different types of nitrogenous bases are found in DNA: adenine (A), thymine (T), cytosine (C), and guanine (G). In RNA, the thymine is replaced by uracil (U).
What does a nitrogenous base look like in DNA?
Figure 2: The four nitrogenous bases that compose DNA nucleotides are shown in bright colors: adenine (A, green), thymine (T, red), cytosine (C, orange), and guanine (G, blue).
Are nitrogenous bases proteins?
The four nitrogen bases that make up DNA are adenine, guanine, cytosine and thymine. When the genetic information is copied to RNA, a similar molecule that is used to create a protein, thymine is replaced by the base uracil. In the genetic code, the bases are abbreviated A, G, C, T and U.
How many nitrogenous bases are there in DNA?
There are four nucleotides, or bases, in DNA: adenine (A), cytosine (C), guanine (G), and thymine (T). These bases form specific pairs (A with T, and G with C).
What is nitrogenous base pair?
base pair, in molecular biology, two complementary nitrogenous molecules that are connected by hydrogen bonds. Base pairs are found in double-stranded DNA and RNA, where the bonds between them connect the two strands, making the double-stranded structures possible.
What is nitrogenous base?
Nitrogenous Base Definition. Several chemicals with a similar cyclic structure, each known as a nitrogenous base, play several important roles in biology. Not only is a nitrogenous base the building blocks for genetic information carrying molecules like DNA and RNA, but different forms of the nitrogenous base serve in various cellular roles ...
What is the name of the bond between nitrogenous base and nitrogenous base?
Note how each nitrogenous base pairs with the nitrogenous base across from it. This is called base pairing, and is an important part of DNA replication, repair, and maintenance. Seen here in a proper configuration, each pyrimidine pairs with a purine, allowing several hydrogen bonds to be formed.
What is the most recognized nitrogenous base?
The most recognized of these molecules is adenine triphosphate, more commonly known as ATP.
How many nitrogen bases are there in DNA?
When talking about a nitrogenous base in the context of DNA or RNA, it is important to note that there are two base classes of nitrogenous base. Every nitrogenous base shares one feature: a six-sided ring with 4 carbon atoms and 2 nitrogen atoms. A purine has an additional 5-sided ring, created by 1 more carbon and 2 more nitrogen atoms. A pyrimidine nitrogenous base has only 1 six-sided ring. Each nitrogenous base has unique bonds, which makes it function in a unique way within the DNA or RNA. Each base can be seen in the image below.
What is the bond between nitrogen and oxygen?
The bonds formed between the phosphorous group and the oxygen of the next 5-carbon ring are called a phosphodiester bond, and form the backbone of both RNA and DNA.
What is the role of nitrogenous base in cell signaling?
A nitrogenous base can also serve important roles in cell signaling, a process known as signal transduction. The general scheme involves a number of chemical messengers acting on various proteins within a cell to send a signal.
What are the three bases that make up a nitrogenous base called?
Rather, each nitrogenous base is read as a unit, with two other bases. These three-base information packets are called codons. Each codon specifies a certain amino acid. Put together in proper order and folded into shape, a chain of amino acids creates a protein.
Examples of nitrogenous in a Sentence
Recent Examples on the Web Mammals excrete their nitrogenous waste as urea in pee, but birds excrete it as uric acid in a sticky white paste. — David Treuer, Harper's Magazine, 26 Oct.

What is nitrogen in chemistry?
Chemistry, Biochemistry. a nitrogen-containing organic compound that has the chemical properties of a base, especially a pyrimidine or purine: Four nitrogen bases are present in a DNA molecule.
What are the bases of DNA?
The bases may be attached to a sugar (deoxyribose in DNA , ribose in RNA) to form nucleosides.The addition of a phosphate to a nucleoside results in the formation of a nucleotide, which is the basic constituent of nucleic acids.
