英语翻译
• DNA is a polydeoxynucleotide and among the largest of the biological macromolecules; some DNA molecules comprise more than 108 nucleotides.They contain adenine,thymine,guanine,and cytosine as the bases,and the genetic information is encoded within the nucleotide sequence,which is precisely defined over the entire length of the molecule.one of the simplest methods for determining the nucleotide sequence of DNA makes use of an enzyme,DNA polymerase,which catalyzes the synthesis of DNA
