It refers to 4 of the nitrogenous bases associated with DNA.
A = Adenine
T = ThymineC = CytosineG = Guanine
The sequence AT CG may also refer to a specific sequence of these nucleotides which function as a signal. This is the "code" for DNA, that organisms need in order to function properly.

It represents the four nitrogen bases that connects the two backbones of the DNA.

  • A: adenine
  • T: thymine
  • C: cytosine
  • G: guanine

What is a symbol that could represent a number?

In mathematical equations letters of the alphabet are used to represent numbers. Letters in the beginning of the alphabet, a, b, c...,etc typically represent Constants. Letters at the end, x, y, z..typically represent Unknowns, or variables.


What do the letters of the DNA alphabet stand for?

CTGAWhile A, T, C, and G represent a particular nucleotide at a position, there are also letters that represent ambiguity. Of all the molecules sampled, there is more than one kind of nucleotide at that position. The rules of the International Union of Pure and Applied Chemistry (IUPAC) are as follows:[1]A = adenineC = cytosineG = guanineT = thymineR = G A (purine)Y = T C (pyrimidine)K = G T (keto)M = A C (amino)S = G C (strong bonds)W = A T (weak bonds)B = G T C (all but A)D = G A T (all but C)H = A C T (all but G)V = G C A (all but T)N = A G C T (any)
