Today in Green science, we studied chromosomes and how they develop into Sex cells. I learned that the chromosomes, first duplicate themselves, then move to the end of the cell and split into new cells. They duplicate themselves again to make four new cells. I also learned that , in the human body, there are 46 chromosomes in the body cell, and exactly half of that in a sex cell.
In a goldfish, there are at least 90 some chromosomes in the body cell; more than the chromosomes in the human body cell. I learned that the X chromosome is larger than the Y chromosome. According to CNN, the Y chromosome has at least 21 different genes unique to men, which control the operation of the body down to the cell. to read more about this article, then click here: http://www.cnn.com/2005/TECH/science/02/14/gender.brain/index.html
On a different site, http://en.wikipedia.org/wiki/Chromosomes, Chromosomes are a single large macromolecule in the DNA.
