What's New In meiosis the cell goes through similar stages in mitosis and uses similar strategies to organize and separate chromosomes. However, the cell has a more complex task in meiosis. It still needs to separate sister chromatids (the two halves of a duplicated chromosome), as in mitosis. But it must also separate homologous chromosomes, the similar but non-identical chromosome pairs an organism receives from its two parents. These goals are accomplished in meiosis using a two-step division process. Homologue pairs separate during a first round of cell division, called meiosis I. Sister chromatids separate during a second round, called meiosis III. Since cell division occurs twice during meiosis, one starting cell can produce four gametes (eggs or sperm). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase. Stages of Meiosis I In meiosis I, homologous chromosomes are separated into two cells such that there is one chromosome (consisting of

"Why are we doing this again?" “It's for your diary," I explained. “You write things down during the day, then v tomorrow morning you expand on them." 4 “But why?" he asked. “What's the point?" ャ 3 That's a question I've asked myself every day since September 5, 1977. I hadn't known on September 4 that the following afternoon I would start keeping a diary, or that it would consume me for the next thirty-five years and counting. It wasn't something Td been putting off, but once I began, I knew that I had to keep doing it. I knew as wel that what I was writing was not a journal but an old-fashioned, secret diary.
