The "human genome" was sequenced by the Human Genome Project around 2000. But I don't understand what was done and what its significance is. Questions:
- Wasn't a single person's genome sequenced? I.e. we have the 3.3 billion base pairs for some individual, right? So how does that pertain to me since I undoubtedly have different alleles than that person.
- Isn't most of our DNA so-called "junk DNA?" Did the human genome project distinguish the portions that code for proteins from this junk area?
- What determines a "gene"? How do we know where one gene begins and ends, especially given that a gene can comprise up to 2 million base pairs?
- Suppose I have the 3.3 billion base pairs for some individual. What can I do with that information? Don't I need to know much much more in order to make any use of those data?
