How to Label a DNA Structure - Sciencing
2017年4月24日 · Alphabetize the DNA rungs. A DNA strand is made of four bases, classified with the letters A, C, T, and G. A stands for adenine (a purine); C stands for cytosine (a pyrimidine); G stands for Guanine (also a purine); and T represents Thymine (a pyrimidine). The "rules" are that C always pairs with G, and A always pairs with T.

DNA Structure and Function | Biology I Laboratory Manual
The building block, or monomer, of all nucleic acids is a structure called a nucleotide. A nucleotide has three parts: phosphate , deoxyribose sugar , and a nitrogen base . There are four different nucleotides that make up a DNA molecule, each differing only in the type of nitrogenous base.
