Document Summary
Organization of the human genome: each human chromosome is a single linear dna molecule (double helix) with a string of. Genes heredity and evolution! nucleotides that spell out genes and other information! is nearly always found in every cell: the total dna in all the chromosomes of an organism is its genome and a complete genome. What is in a human genome: first full human genome sequenced in 2003, human genome consist of about 3 billion basepairs (3 x109 bp)! Equivalent to a 6 million page book! Protein-coding regions only account for 2% of genome! Molecular de nition of a gene: a gene is the entire nucleic acid sequence that is necessary for the synthesis of a functional. Each diploid human cell has ~2 meters of dna in length if stretched end to end. If all your dna was laid out end to end it could reach the sun and return to earth several times!!!
