Is cytosine not a nucleotide of DNA?
Cytosine is a nitrogenous base that is a component of DNA, but on its own, it is not a nucleotide. In DNA, cytosine pairs with guanine through hydrogen bonding to form a complementary base pair. Nucleotides are composed of a nitrogenous base, a sugar, and a phosphate group.
What is the base unit of a nucleic acid?
The base unit of a nucleic acid is a nucleotide, consisting of a nitrogenous base (adenine, guanine, cytosine, or thymine in DNA; adenine, guanine, cytosine, or uracil in RNA), a sugar molecule (deoxyribose in DNA; ribose in RNA), and a phosphate group.
What are the nitrogenous pair combinations in dna?
In DNA, the nitrogenous base pairs are adenine (A) paired with thymine (T), and guanine (G) paired with cytosine (C). These base pairs are essential for maintaining the DNA double helix structure and are crucial for genetic information storage and replication.
What does the structure of DNA contain?
The structure of DNA contains nucleotides, which are made up of a phosphate group, a sugar molecule (deoxyribose), and a nitrogenous base (adenine, thymine, cytosine, or guanine). The nucleotides are arranged in a double helix formation, with the nitrogenous bases pairing specifically (A with T, C with G) to form the genetic code.
What is the complementary base pair of cytosine?
Guanine goes with Cytosine

What are their nitrogenous base of RNA and DNA?
The nitrogenous bases in RNA are adenine, cytosine, guanine, and uracil, while the nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine.
Which DNA base always pair with cytosine?
Guanine
What are the nitrogenous pair combinations in dna?
In DNA, the nitrogenous base pairs are adenine (A) paired with thymine (T), and guanine (G) paired with cytosine (C). These base pairs are essential for maintaining the DNA double helix structure and are crucial for genetic information storage and replication.
How many different nitrogenous bases exist and are found in Dna?
There are only 4 nitrogenous bases in DNA. These are adenine, thymine, guanine, and cytosine. Adenine will only pair with thymine, and guanine will only pair with cytosine.
Nitrogenous base pair in DNA?
The nitrogenous base pairs in DNA are adenine (A) paired with thymine (T), and cytosine (C) paired with guanine (G). These base pairs are held together by hydrogen bonds, forming the double helix structure of DNA.
What are the DNA base pairing rules?
The DNA base pairing rules are as follows: adenine pairs with thymine and guanine pairs with cytosine. This complementary base pairing is essential for DNA replication and transcription processes.
What is meant by nitrogenous base pairs?
The pair of nitrogenous bases that connects the complementary strands of DNA or of double-stranded RNA and consists of a purine linked by hydrogen bonds to a pyrimidine: adenine-thymine and guanine-cytosine in DNA, and adenine-uracil and guanine-cytosine in RNA.
Which bases does Guanine always bond with to form a pair in DNA?
In a DNA molecule cytosine always pairs with guanine, the same is true for an RNA molecule.
How does each nucleotide differ?
Nucleotides differ in their nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G). The sequence and pairing of these bases define the genetic information stored in DNA. Additionally, each nucleotide is composed of a deoxyribose sugar, a phosphate group, and a nitrogenous base.
What does cytosine always pair with?
Cytosine always pairs with guanine in DNA through hydrogen bonding, forming a stable base pair. This complementary base pairing is a key feature in the double-stranded structure of DNA.
