However, Machiavelli's success did not last. In August 1512 the Medici, backed by Pope Julius II used Spanish troops to defeat the Florentines at Prato, but many historians have argued that it was due to Piero Soderini's unwillingness to compromise with the Medici, who were holding Prato under siege.
The nucleus is the part of a cell that contains the genetic information. The nucleus is surrounded by a nuclear membrane that, like the cell membrane, makes a boundary around the nucleus. Now let's explore chromosomes. Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid, or DNA. Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.
Nuclear DNA and mitochondrial DNA differ in many ways, starting with location and structure. Nuclear DNA is located within the nucleus of eukaryote cells and usually has two copies per cell while mitochondrial DNA is located in the mitochondria and contains 100-1,000 copies per cell.The structure of nuclear DNA chromosomes is linear with open ends and includes 46 chromosomes containing 3 billion nucleotides.uclear DNA encodes for the majority of the genome in eukaryotes, with DNA located in mitochondria and plastids coding for the rest.
