{"Image DocumentName": "Human Genome 23 Pairs of Chromosomes + mtDNA", "Image ImageDescription": "Located in cell nucleus X Y. Autosomes. 2 copies per cell. Located in mitochondria (multiple copies in cell cytoplasm) mtDNA. 16,569 bp. Mitochondrial DNA. Figure 2.3 The human genome contained in every cell consists of 23 pairs of chromosomes and a small circular genome known as mitochondrial DNA. Chromosomes 1-22 are numbered according to their relative size and occur in single copy pairs within a cell\u2019s nucleus with one copy being inherited from one\u2019s mother and the other copy coming from one\u2019s father. Sex-chromosomes are either X,Y for males or X,X for females. Mitochondrial DNA is inherited only from one\u2019s mother and is located in the mitochondria with hundreds of copies per cell. Together the nuclear DNA material amounts to over 3 billion base pairs (bp) while mitochondrial DNA is only about 16,569 bp in length. Sex-chromosomes. Nuclear DNA. 3.2 billion bp. 100s of copies per cell. Figure 2.3, J.M.
