• • Genetic material is double-stranded DNA arranged into a number of separate linear chromosomes. Located in the membrane-bound nucleus
• • Genome is larger, contains more non–coding DNA and more genes
• • Chromosomes Contain many small structural proteins called histones that are shaped like spheres. Long thin DNA molecules are wound around a series of these histones forming structures called nucleosomes → coil to form chromatin→ supercoiled to form chromosomes
• • Mitochondria and chloroplasts are organelles in the eukaryotic cells that contain DNA. this DNA is known as non-nuclear DNA and is inherited independently of nucleus (chromosomal) DNA. 
• • For stability and protection against degradation, the ends of chromosomes are made up of repeating DNA sequences called telomeres
• • Mitochondrial DNA (mtDNA) is inherited from the mother and hence is useful in studies of evolutionary relatedness by tracing maternal inheritance
