In genetics, the portion of a nucleotide molecule that contributes to the genetic code. DNA bases include adenine, thymine, guanine, and cytosine; in RNA, uracil replaces thymine.
The components of DNA which pair to make the ‘rungs' of the DNA ladder. There are four types of bases in DNA which bond in complementary pairs: Adenine to Thymine and Cytosine to Guanine. In RNA, the base Uracil replaces Thymine.
The chemical units (adenine, thymine, guanine and cytosine) in a DNA molecule that constitutes the genetic code.
a codon that specifies a particular amino acid
One of four chemicals (Adenine, Cytosine, Guanine and Thymine) that make up DNA.
The variable part of DNA. The nitrogenous bases of DNA are divided into two groups: purines [adenine (A) and guanine (G)] and pyrimidines [thymine (T) and cytosine (C)]. In RNA, thymine is replaced by uracil (U). Modified and unusual bases, such as pseudouridine, are found in tRNA molecules.
Compounds that read with acids to form salts plus water. Alkalis are water soluble bases used in petroleum refining to remove acidic impurities. Oil soluble bases are included in lubricating oil additives to neutralize acids formed during the combustion of fuel or oxidation of the lubricant.
Compounds that make water Alkaline. If water contains more acids than bases it's acidic. If it has more bases than acids it's alkaline.
Adenine (A), cytosine (C), guanine (G) and thymine (T) are molecules that make up DNA. Bases in DNA form two pairs of complementary molecules, hydrogen bonds can link adenine to thymine and guanine to cytosine. If the sequence of bases matches a complementary sequence in a second strand of DNA the bonds can hold the two strands together (Watson-Crick pairing) and form double-stranded DNA.
Nitrogenous compounds that interact to form the molecular building blocks of DNA and RNA: adenine, cytosine, guanine, thymine, and (in RNA only) uracil.
There are four bases which join together to form DNA: Adenine, Guanine, Thymine and Cytosine, commonly identified by their initials A,G,T and C. The bases join end to end to give a molecule of DNA. The bases join in a specific sequence, and it is this base sequence that represents the genetic plan.
Substances also known as alkaline. In the context of this website, used to describe a number of chemicals that are used as instruction code by DNA and RNA. These are abbreviated A, T, C, G in DNA and A, U, C, G in RNA.
The four building blocks of DNA are called bases. The building blocks are Cytosine, Guanine, Thymine, Adenine and are commonly referred to as C, G, T, A.
gene determining subunits of nucleic acids; visualize a nucleic acid alphabet with 4 letters. The letters are A, C, G, and T for DNA.
Major components of DNA. They are made up of nitrogen and carbon atoms in a ring structure. There are two types of bases: purines (adenine and guanine, known as A and G) and pyrimidines (cytosine and thymine, known as C and T). The bases stick to each other in pairs in the DNA double helix. A binds to T, and C binds to G. The order of bases in the DNA molecule determines the order of amino acids in the proteins it encodes.
The molecular building blocks of DNA and RNA: adenine, cytosine, guanine, thymine, and (in RNA only) uracil. In DNA, A attaches only to T, and C attaches only to G. In RNA, A attaches only to U, and C attaches only to G.
(In DNA) Four building blocks of nucleic acids. They are Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). They are complementary in that the only stable base pairs are AT/TA and GC/CG. The length of DNA fragments is measured in base pairs (bp).
