What do the letters of the DNA alphabet stand for?

Answer 1

CTGA

While 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 = adenine
• C = cytosine
• G = guanine
• T = thymine
• R = 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)

Answer 2

DNA stands for DeoxyriboNucleic Acid

The letters A, G, C, and T represent the four nitrogen bases of DNA. They are adenine, guanine, cytosine, and thymine. Three nitrogen bases make up a codon, which represents a particular amino acid. The sequence of nitrogen bases in DNA specifies the sequence of amino acids in a protein. The shape and function of a protein is determined by the sequence of its amino acids.

Answer 3

A means adenine T means thaimine G means guanine C means cytosine

Answer 4

A sequence of nucleotides which is then transcribed into mRNA and translated into a protein

Answer 5

The letters stand for the four nitrogenous bases that make up the "code" of DNA.

A-Adenine

T-Thymine

G-Guanine

C-Cytosine

Answer 6

DNA stands for "deoxyribo nucleic acid".
