Chromosome 21 - Human-Chimp Comparison

  • One of the threadlike "packages" of genes and other DNA in the nucleus of a cell. Different kinds of organisms have different numbers of chromosomes. Humans have 23 pairs of chromosomes, 46 in all: 44 autosomes and two sex chromosomes. Each parent contributes one chromosome to each pair, so children get half of their chromosomes from their mothers and half from their fathers.Chromosome 21 fully Determining the order of nucleotides in a DNA or RNA molecule, or the order of amino acids in a protein molecule.sequenced and annotated

  • Two clusters with significant differences
