DNA (ADN)
Abstract
The DNA (Deoxyribonucleic Acid) is the molecule where the genetic information is codified. The sequences of different nitrogenous bases causes differences in the genomic expression, causing variance in the organisms. There are four principal organelles in eukaryotic cell where the DNA can be found, chloroplast, mitochondria, nucleus and ribosome, but the DNA in the nucleus participate in most of the phenotypic expression.
