<span>Molecular scientists can read the DNA code and compare the DNA of different organisms. This concept is ude in molecular clocks to determine the Moleular Phylogenies. It is letter B. Hereditary molecular differences are being analyzed in phylogeny which is mainly from the DNA sequence in order to acquire information on the evolutionary relationships of an organism.</span>
Chromosomes are made of condensed coils of DNA. Genes are segments on a chromosome that carry the code for a specific trait. Alleles are contrasting forms of a gene.
