Mitosis and Meiosis
2008-04-10 10:11:00 Interphase precedes both mitosis and meiosis and is the period between cell divisions during which time the chromosomes replicate and the chromosomes are not visible (loosely packed). During interphase, two pairs of centrioles lie next to each other, just outside the nucleus. Mitosis is a process where in, one parent cell gives rise to two identical daughter cells. Mitosis can be divided into four stages: Prophase, Metaphase, Anaphase and Telophase. Prophase: Chromosomes (two identical copies) condense, each chromosome has two arms and each copy of chromosome is called Chromatid. Spindle fibers form at centriole and centriole begin to separate. In addition, nuclear membrane disappears. A short period just before metaphase, called prometaphase, comprises movement of centrioles to opposite ends of the cell and attachment of spindle fibers to each of the chromatids. Metaphase: Chromosomes line up along an imaginary line, called the metaphase plate that divides the cell into two. The s...

Meiosis and Mitosis Tutorial
2008-01-09 08:53:00 I recently caught wind of Openlearn, at Open University, which is a UK university that is dedicated to distance learning. Apparently started in 1969, and hosting part-time students who will received real degrees, the OU’s teaching quality was listed as the fifth best in the UK. “Now anyone can access free ...
Mitosis
2008-01-05 06:29:00 Mitosis means the replication of and the division of a cell’s nucleus. These day — the usage of cell phones is multiplying rapidly. Today 38 % of US consumers are watching shows online, 36% use their cell phones as an entertainment device, and 45% are creating web content. At least that’s what a new suvey from ...
Andrew Bird releases new video for Imitosis
2007-08-23 05:53:00 Hello Pals ? it may be the last hazy doldrums of summer but there's still news to be had. Most excitingly of all ? we are excited to announce the debut of the brand new video for IMITOSIS! Please turn your attention towards http://myspacetv.com/index.cfm?-fuseaction=vids.individual&-videoid=16001163 for the exclusive debut ? it will be here at myspace for the coming week and then will live on Andrew's website (in higher resolution, may I add?. So you can see it in its full glorious hifi fidelity) This magical little film was directed by stop motion animation wizardess Britta Johnson. CHICAGO CITIZENS! We are looking forward to seeing you soon at the Hideout Block Party on September 8 ! It is a weekend full of great music and much fun ? and will also be Andrew's last local show this year (no Logan Square Thanksgiving shows this year?) So put on your dancing shoes and come on down, it's a great weekend of music at one of the friendliest venues on earth. More informati...
Mitosis and Meiosis
2007-08-14 16:51:00 Mitosis is the biological process involving chromosomal duplication and nuclear division. Mitosis is usually followed by cytokinesis, whereby the watery environment inside a cell, known as the cytoplasm, and cell membrane divide. Two identical cells are generated, each having the same number of chromosomes as the parental cell. Somatic cells (meaning any cell that is ...

Visualizing the Stages of Mitosis
2007-07-10 01:45:00 Via a Hungarian Polish science blog that kindly links to me often enough, I came across a great YouTube clip describing the stages of mitosis with beautiful graphics. While I can’t understand Hungarian Polish at all, Miggawki looks like a very nice science blog, with interests rather comparable to my own. The videoclip ...
