Organisms have all genetic material in chromosomes {genome, genetics}|. Typical animal cells express 4,000 to 10,000 genes. Humans have more than 30,000 genes. Two unrelated people differ in 100 to 5000 genes. Human genes differ from chimpanzee genes by one percent. Humans have 85,000 different mRNAs.
Transposable elements are 45% of human DNA. Non-coding DNA is 24% of human DNA. Structural DNA is 20% of human DNA. Repeated sequences are 10% of human DNA.
Protein coding genes are 1% of human DNA. 42% of genes have not been characterized. 14% are nuclear transcription factors. 12% are messengers. 10% are enzymes. 5% are miscellaneous. 5% are structural. 5% are for molecular transport. 3% are cell-surface proteins. 3% are tumor-suppressor genes. 1% are immune-system proteins.
People have 5 x 10^9 nucleotides. Unrelated people differ by 5 x 10^5 nucleotides.
