WebAug 31, 2012 · 8. @nico is right. the number of chromosomes is the result of an evolutionary timeline, puncutated by sometimes spontaneous events which shape the DNA. These events occur in the course of evolution: 1) Chromosomal rearrangements. Large sections of the genome can flip around or become integrated in other chromosomes. WebChromosomal DNA consists of two DNA polymers that make up a 3-dimensional (3D) structure called a double helix. In a double helix structure, the strands of DNA run antiparallel, meaning the 5’ end of one DNA strand is parallel with the 3’ end of the other DNA strand.
