# Genome --- Your **genome** is like a catalog of all the [[gene|genes]] in someone's DNA. "Genome sequencing" is the reading out the genome of an organism. ## Genomics **Genomics** is the study of genes, genes (i.e. the complete nucleotide sequence including all introns and regulatory sequences as well as repeated elements), RNAs, and/or proteins of a genome. Our cells are doing all the things we have talked about this class ALL THE TIME. While biochemical processes can be indentified and isolated (DNA sequencing is just an adaptation of DNA replication). *The biochemistry of any cell is a function of the expression of the entire genome.* Most of the genes who's functions we understand are [[gene#Housekeeping Genes|"housekeeping genes"]] because we share so many of these with our bacterial ancestors. ## The Human Genome Project The **Human Genome Project** was a massive undertaking when it was taking place. Because of that work we have catalogued all the kinds of genes that we as humans have (about 23,000 genes!). Surprisingly, a vast majority of what we have in our genome is filler and junk. ![[human genome project.png]] ___
