Obviously, the cost to sequence a genome depends on its size. The discussion below is focused on the human genome; keep in mind that a single 'representative' copy of the human genome is ~3 billion bases in size, whereas a given person's actual (diploid) genome is ~6 billion bases in size.
Alternatively, EPA has a more beneficial effect on lowering overall LDL (bad) cholesterol. In the cognitive domain, DHA appears to offer greater mental benefits. DHA has been suggested to be more effective in improving overall cognition and preventing cognitive decline in healthy older adults.
Docosahexaenoic acid (DHA) is an omega-3 fatty acid found in cold-water, fatty fish, such as salmon. It is also found in fish oil supplements, along with eicosapentaenoic acid (EPA). Vegetarian sources of DHA come from seaweed. Omega-3 fatty acids are good for your heart, and your body needs DHA for a healthy brain. Infants need DHA, especially during the first 6 months of their lives, so their brains, eyes, and nervous systems can develop as they should. DHA is found in breast milk and is added to some infant formula.
