What happens in meiosis during telophase II? Meiosis: The main purpose of meiosis is to generate four unique daughter cells that are haploid, meaning they have half the number of chromosomes. Meiosis is a type of cellular division that produces the male and female sex cells called gametes (spe...
What is the principle difference between anaphase I and anaphase II of meiosis?What happens in meiosis and what does it mean?Meiosis comes from a Greek word that means "to lessen" and refers to the fact that the cell division reduces the chromosome number by half. This cell...
Meiosis is divided into meiosis I and meiosis II. Like mitosis, the onset of meiosis I is preceded by all 46 of a cell's chromosomes replicating. In meiosis, however, after the nuclear membrane is dissolved in prophase, the homologous chromosomes pair off, side by side, with the homolog d...
Finally, we need to know the cell organelle which plays an important part in mitosis/meiosis. They are centrosomes. Centrosomes are made up of microtubules andcentrioles. Microtubules form the spindle fibers and centrioles help organize the spindle into proper formation. Now we can pay to att...
If, as you say, "science will have to be content with observing the process as it now stands," then how have they created a beating heart from stem cells, and why is the military investing billions in "limb factories" for future 'forever soldiers'?
The second step is called fertilization. In it, the two cells merge into one. This restores the diploid state. Fertilization is what happens when a female's ovum (or "egg") joins together with a male's sperm and they form a zygote. ...
Telophase is the final phase of mitosis, and this is when the official division of one cell into two happens. First, the chromosomes relax back into chromatin and a nuclear envelope forms around each chromatin blob, making it into a brand new nucleus. A nucleolus appears in each of these ...
In this lesson we'll go over what cell division is in different types of cells and look at the factors that stop cells from dividing. We'll also learn what happens when cell division doesn't stop. What Is Cell Division? All life starts with a single cell. That cell multiplies as we ...
It can determine cell fate, as it does in developing neural tissue. It can also dictate tissue architecture, as it does in many epithelia. One way to ensure the correct angle of cell division is through controlled orientation of the spindle at metaphase. What happens when that control is ...
