A base found in DNA and RNA and derived from pyrimidine; pairs with guanine
Cytosine is one of the four main bases found in DNA and RNA. It is a pyrimidine derivative, with a heterocyclic aromatic ring and two substituents attached (an amine group at position 4 and a keto group at position 2). The nucleoside of cytosine is cytidine. ...
One of the pyrimidine nitrogenous bases occurring in both DNA and RNA. PICTURE
A pyrimidine base that is a component of nucleotides and thus a normal component of DNA and RNA. See the Figure at NHGRI.
A nitrogenous base, one member of the base pair G- C (guanine and cytosine).
A pyrimidine base found in DNA and RNA.
One of the four types of 'base' that spells out our DNA code. When a base is attached to a phosphate and sugar, it makes up a nucleotide, one of DNA's 'building blocks'. In the double-helical structure of DNA, C (cytosine) pairs with G (guanine). A is also present in RNA. ...
A pyrimidine base; one of the four molecules containing nitrogen present in the nucleic acids DNA and RNA; designated by letter C.
A chemical that is a basic structural unit of a living thing's DNA. It is one of 4 key bases or nucleotides (adenine (A), guanine (G) and thymine (T)) that repeat throughout the length of a DNA chain. The order of their sequence defines the arrangement of genes.
