NATS 1675 Lecture Notes - Lecture 8: Sister Chromatids, Robert Crippen, Pocket Cube
Document Summary
Nats 1675 lecture #8 - cell division continued / genetics. We have just 47 chromosomes [but without crossover] 23 = we refer to a pair of chromosome 2x2x2 =8. The formula above, for humans it will look like 223 so that will be = > greater than) 8 million. So each individual are able to produce 8 million [if male, 8 million sperm cells, if women, Homologous pair of chromosomes (those that have undergone synapse) line up on the equatorial plate. As we move from prophase i to metaphase i, synapse has already happen. The pairs of the homologous chromosomes separate. At each pole, there is a complete haploid set of. Telophase i: chromosomes (but each chromosome still has two sister chromatids) A furrow appears and by the end of this stage, the parent cell has divided into two daughter cells. One thing in humans, the nuclear envelope does reform at telophase i.
