Adenine pairs with thymine, and cytosine pairs with guanine.
What else can I help you with?
Four kinds of nitrogenous base?
The four nitrogenous bases found in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G). These bases pair up in specific combinations to form the "rungs" of the DNA double helix, with adenine pairing with thymine and cytosine pairing with guanine.
What makes up the rungs for DNA?
The rungs of DNA are composed of nitrogenous bases, specifically adenine (A) pairing with thymine (T), and cytosine (C) pairing with guanine (G). These base pairs are held together by hydrogen bonds, forming the double helix structure of DNA.
The code of DNA is specified in?
The code of DNA is specified in the sequence of nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G). These bases pair up to form the double helix structure of DNA, with A pairing with T and C pairing with G. This sequence of bases contains the instructions for building and functioning of an organism.
What holds the two strands of a DNA molecule of each other?
Hydrogen bonds
How are the two complementary strands of DNA connected to each other?
The two complementary strands of DNA are connected to each other through hydrogen bonds between the nitrogenous bases. This bond forms a double helix structure, with adenine pairing with thymine and cytosine pairing with guanine.
What structural feature helps DNA replicate?
complementary pairing of nitrogenous bases

What are the ladders of DNA made of?
The 'steps' on the 'DNA Ladder' are made up of the four nitrogenous bases, Cytosine, Guanine, Thymine, and Adenine, while the pairing bases (Adenine & Thymine, Cytosine & Guanine) are bonded together with a hydrogen bond. The pairing bases (the 'rungs' of the ladder) are connected to the side posts of the ladder, which contain phosphate.
What is the attraction between nitrogenous bases?
The attraction between nitrogenous bases is due to hydrogen bonding. This bonding occurs between specific pairs of bases in DNA (adenine-thymine, guanine-cytosine) and RNA (adenine-uracil, guanine-cytosine), contributing to the stability of the double helix structure.
What are the nitrogenous bases in DNA and how do you know whether there are two bonds or three?
The four nitrogenous bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G). In DNA, adenine pairs with thymine with two hydrogen bonds, and cytosine pairs with guanine with three hydrogen bonds. This pairing is based on the structure and chemical properties of the bases, which allow for complementary base pairing.
Who discovered the nitrogenous bases of DNA please need this quick.?
Erwin Chargaff is credited with discovering the nitrogenous bases of DNA and establishing the base pairing rules (Chargaff's rules) that helped lead to the discovery of the double-helix structure of DNA by Watson and Crick.
What makes up the rungs for DNA?
The rungs of DNA are composed of nitrogenous bases, specifically adenine (A) pairing with thymine (T), and cytosine (C) pairing with guanine (G). These base pairs are held together by hydrogen bonds, forming the double helix structure of DNA.
In the Watson-Crick model of a double helix the steps of the spiral staircase are composed of?
In the Watson-Crick model of a double helix, the steps of the spiral staircase are composed of nitrogenous bases. These bases include adenine (A) pairing with thymine (T) and cytosine (C) pairing with guanine (G) through hydrogen bonds.
The code of DNA is specified in?
The code of DNA is specified in the sequence of nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G). These bases pair up to form the double helix structure of DNA, with A pairing with T and C pairing with G. This sequence of bases contains the instructions for building and functioning of an organism.
What are the bases present in the DNA of a mammal?
The DNA of mammals contains four nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G). These bases pair specifically, with adenine pairing with thymine and cytosine pairing with guanine, forming the rungs of the DNA double helix. This sequence of bases encodes genetic information crucial for the development and functioning of the organism.
Why is it very needful to have a correct pair of nitrogenous bases?
Having the correct pair of nitrogenous bases is essential for accurate DNA replication and protein synthesis. Base pairing ensures that the genetic code is preserved during cell division, preventing mutations that could lead to diseases. Additionally, proper base pairing allows for the formation of stable double helices, which is crucial for the structural integrity of DNA. Ultimately, accurate base pairing underpins the fidelity of genetic information transfer across generations.
What best describes the correct pairs of DNA bases?
The correct pairs of DNA bases are adenine (A) with thymine (T), and cytosine (C) with guanine (G). This pairing is based on the complementary base pairing rule in DNA, where A always pairs with T and C always pairs with G.
