But the latest science demands another important nutrient be added to that diet: DHA, docosahexaenoic acid, an omega-3 fatty acid. DHA is brain nutrition. It's to our brains as calcium is to our bones. In fact, optimal infant brain and eye development and function depends on it.*.
So who is Generation X? Generation X is the name given to the 'birth dearth', those born in the 60's and 70's; the valley between the Boomers and Generation Y (the boomlet)12. Generation X grew up in the shadow of their Boomer parents and initially defied tidy descriptions and categories.
The X chromosome is one of the two sex chromosomes in humans (the other is the Y chromosome). The sex chromosomes form one of the 23 pairs of human chromosomes in each cell.The X chromosome spans about 155 million DNA building blocks (base pairs) and represents approximately 5 percent of the total DNA in cells.emales have two X chromosomes, while males have one X and one Y chromosome. Early in embryonic development in females, one of the two X chromosomes is randomly and permanently inactivated in cells other than egg cells. This phenomenon is called X-inactivation or Lyonization.
