Base Pair – Genome.gov
A base pair consists of two complementary DNA nucleotide bases that pair together to form a rung of the DNA ladder. DNA is made of two linked strands that wind around each other to resemble a twisted ladder — a shape known as a double helix. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases: adenine (A), cytosine (C), guanine (G) [GWA-NeeN] or thymine (T). The two strands are held together …

In DNA, the bases are adenine (A), thymine (T), guanine (G), and cytosine (C). In RNA, the bases are adenine, guanine, uracil, and cytosine. Pentose Sugar In DNA, the sugar is 2′-deoxyribose. In RNA, the sugar is ribose. Both ribose and deoxyribose are 5-carbon sugars.

How do the bases of DNA bond together? – KnowledgeBurrow.com
Human genes are commonly around 27,000 base pairs long, and some are up to 2 million base pairs. What base pairs go together in DNA? DNA base pair. Under normal circumstances, the nitrogen-containing bases adenine (A) and thymine (T) pair together, and cytosine (C) and guanine (G) pair together. The binding of these base pairs forms the …

Base pair – Wikipedia
A base pair is a fundamental unit of double-stranded nucleic acids consisting of two nucleobases bound to each other by hydrogen bonds. They form the building blocks of the DNA double helix and contribute to the folded structure of both DNA and RNA. Dictated by specific hydrogen bonding patterns, Watson-Crick base pairs allow the DNA helix to maintain a regular helical structure that is subtly dependent on its nucleotide sequence. The complementary nature of this based-paired …

The 4 DNA Bases and Their Strict Pairing Rules – Biology Wise
With the discovery of the chemical structure of DNA, by Watson and Crick in 1953, the double helical structure of DNA and the arrangement of the bases in the said structure was revealed. The structure consists of two DNA strands linked to each other with the help of hydrogen bonds, and arranged in a spiral manner. It shows the presence of four unique nucleobases, whose arrangement in random sequences leads to the formation of the genetic code of an organism. A nucleobase is an alternative …

In DNA, these bases are cytosine (C), thymine (T), adenine (A) and guanine (G). Note: These are called bases because that is exactly what they are in chemical terms. They have lone pairs on nitrogens and so can act as electron pair donors (or accept hydrogen ions, if you prefer the simpler definition).

What are the nitrogen bases in DNA bonded to? – Answers
The four nitrogenous bases are A (adenine), C (cytosine), G (guanine) and T (thymine) in DNA. They are bonded to the deoxyribose in the sugar-phosphate backbone at the 1′ position.
