Document Summary
A combination of the dna molecule that carries genetic information and proteins that compact and regulate the dna. Each arm is one dna double stranded molecules. The two arms are squished so tightly together, you can"t resolve from one another. The position of the centromere is a useful marker. They are named based on the position of their centromere. Telocentric - at the end, only one arm. In most of our cells, we have a duplicate set of chromosomes. One copy of genetic material (chromosome) subdivided into chromosomes. Two copies of genetic material (chromosome) subdivided into chromosomes homologous chromosomes: a pair of matching chromosomes, one homolog from each parent. Multiple copies - in human cells - just means terminally differentiated - never going to divide terminally differentiated - never going to divide again. Autosomes: present in the same copy number in both males and females; number and morphology of autosomes is species-specific.
