The numbers game
However, they do pose a threat to spacecraft because of their extremely ... the inclination (or plane of the orbit relative to the Equator) the satellite will end up in can be calculated using some relatively simple trigonometry. Once the inclination ...
Replication and Distribution of DNA during Mitosis
But how does ... phases of mitosis as it orchestrates the movement of sister chromatids to opposite poles of the cell (Figure 2). Following prometaphase, metaphase begins. At the start of metaphase, the microtubules arrange the chromosomes in a line along ...
El Niño Odds Raised to 70% by NOAA, But El Niño is Actually Imminent
This is a follow-up post to the ones he did on February 21 ... In addition, warmer than average sea-surface temperatures extend along the Equator from South America all the way to the Date Line. This is a classic “Full-basin” El Niño expression.
The Eukaryotic Cell Cycle: A Masterpiece of Design
Have you ever wondered how the eukaryotic cell knows when to transition from one phase of its cycle to the next? How does the cell know to ... produce two daughter cells). Chromatids attach to the mitotic spindle (made up of microtubules that radiate ...
Replication and Distribution of DNA during Meiosis
Because each chromosome was duplicated during the S phase that occurred just before prophase I, each now consists of two sister chromatids joined at ... the chromosome pairs then line up along the equator of the cell, termed the metaphase plate (Figure ...
