Mitosis is the Greek word for thread, after the thread-like chromosomes that can be seen under the microscope in dye-stained cells during cell division. Meiosis means a “lessening” in Greek. This refers to the outcome of meiosis, where the genetic information in each new cell is halved....
· Cover the sample (root tip) with a coverslip and gently press the coverslip down, then examine the slide under the microscope starting with low magnification * For this experiment, a properly prepared slide should appear light pink due to the stain to almost colorless....
Because each duplicated chromosome consists of two identical sister chromatids joined at a point called the centromere, these structures now appear as X-shaped bodies when viewed under a microscope. Several DNA binding proteins catalyze the condensation process, including cohesin and condensin. Cohesin...
this crossing over results in a shuffling of the genetic information in the gametes. The number of locations where genetic information was exchanged by crossing over often is indicated by the formation ofchiasmata. These chiasmata are visible under the microscope during prophase I. Chiasmata resu...
Microtubules that will form the mitotic spindle extend between the centrosomes, pushing them farther apart as the microtubule fibers lengthen. The sister chromatids begin to coil more tightly with the aid of condensin proteins and become visible under a light microscope....
The first three phases comprise what is known as interphase, a state in which chromosomes are stretched in the form of chromatin fibers, which cannot be seen under a light microscope. In the M phase, mitosis, a process in which the sister chromatids separate and the nucleus divides, and ...
That’s where web animations of mitosis might come in handy for you.Watching mitosis in action through web animations can help give you an idea of what all those verbal descriptions really mean.They can also help you picture what the phases of mitosis might look like under a real microscope...
