Step 1:
The bacterium cell must copy its DNA so the new cells will have DNA. DNA or, deoxyribonucleic acid, has all of the information the bacterium will need to survive, so it is important it gets copied. The DNA is tightly wound so it is in a neat package called a chromosome.
Steps 2 and 3:
The bacterium now grows larger. This allows for some separation between the two DNA copies that are inside the cell. A division develops in the middle of the bacterium. This division eventually completely divides the bacterium in half. This is called cytokinesis.
Step 4:
Each cell is now called a daughter cell and they separate.
The steps of binary fission
binary fission
Binary fission results in two identical daughter cells. This is a type of asexual reproduction, or creating genetically identical offspring. If humans were able to reproduce using binary fission, it would look something like this: your mother or father would grow larger, and inside all of his or her DNA would be copied. Eventually your parent would split in half creating an identical clone.
<h2>Function of Macrophages</h2>
Explanation:
- <em>Macrophages are effector cells of the</em> <em>innate immune system</em> that phagocytose microscopic organisms and emit both expert incendiary and antimicrobial middle people
- The <em>macrophages </em>assume a significant role in wiping out <em>unhealthy and harmed cells through their customized cell death </em>
- <em>Macrophages </em>are produced through the separation of <em>monocytes</em>, which transform into <em>macrophages when they leave the blood</em>
- There are two kinds of tissue macrophages such as <em>macrophages that live inside explicit organs/tissue (free macrophages and fixed macrophages) and macrophages</em> got from monocytes in response to inflammatory stimuli
Embryologist study embryos because Embryology is central to evolutionary developmental biology ("evo-devo"), which studies the genetic control of the development process (e.g. morphogens), its link to cell signalling, its roles in certain diseases and mutations, and its links to stem cell research.
A) 12 chromosomes in a gamete
B) 46 chromosomes in prophase 1!
