To know the similarities between Mitosis and Meiosis, you need to know about the cell. And also what cell division is.
Well, to start, a cell is the fundamental component of a body. Cells are what forms living organisms. And for living organisms to grow and survive, cell division is important.
Cell division plays a very important role in genetic diversity. Cells divide on their own. It is a process through which new cells get reproduced. And this division of cells keeps happening every second, every minute, and every hour of the day. It is an unending process.
Why is Cell division important?
You might have at times noticed that when you fall, and an injury happens, you get bruises. But in a couple of days, these bruises start healing on their own – well, that is nothing but cells getting divided. The cells get divided so that new cells can form, and in turn, new skin gets formed.
Another reason why cells divide is for their growth and development.
Cell theory defines that new cells come from pre0existing cells. When a cell divides and transforms from one phase to another, we refer to it as Cell Cycle.
Now when the cell divides into two types Mitosis and Meiosis. Let us understand what these are and how they are these similar.
What is Mitosis?
The part of the cell cycle that gets replicated and separated into two new nuclei is what we refer to as Mitosis. When cell division happens, the total number of chromosomes is often maintained. That is the reason why we refer it to as equational division.
During Mitosis, different phases happen depending on what set of activities complete first. These phases are Prophase, Prometaphase, Metaphase, Anaphase, and then Telophase.
Mitosis occurs in eukaryotic cells. It does not happen in Prokaryotic cells. Because they lack a nucleus and have an altogether different process. Depending upon the species, also Mitosis happens in different ways. Animal cells usually undergo “Open Mitosis.” Here before the chromosome gets separated, the nuclear envelope breaks.
Most human cells are as normal produced by mitotic cells division.
Now let’s look at what is Meiosis.
What is Meiosis?
Meiosis is where a single cell will divide two times. Then it will produce four more cells. These contain cells, half of it has original genetic information. These cells are what we call sex cells. In males, the sex cells are sperms. And in the female sex, cells are eggs.
It is also said that during Meiosis, one cell gets divided into four daughter cells. Like Mitosis, Meiosis also has different phases. But a asv phase or two differs. The phases under Meiosis are Interphase, Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis.
Unlike Mitosis, in Meiosis, when the cell gets replicated. It further gets divided into four daughter cells. Each of these cells has half the number of chromosomes present in the parent cell.
These two divisions are what we call Meiosis I and Meiosis II. Meiosis happens in all single-celled or multicellular organisms. But these organisms should be capable of sexually-reproducing.
Now that you know what Mitosis and Meiosis are, let’s try and see what things are similar in both.
Similarities between Mitosis and Meiosis?
Although different in nature, there are certain things that are similar in both. We are going to list down the similarities between Mitosis and Meiosis below:
- Under a microscope, you will find that both Mitosis and Meiosis happens in the cell nuclei.
- Cell division is an integral process of Mitosis and Meiosis.
- In both Mitosis and Meiosis, the cell division will occur in the M phase in the cell cycle.
- In both the cell cycles. Cell division happens in similar phases like Metaphase, Anaphase, Telophase, and Prophase.
- DNA synthesis happens in both cell cycles.
- Both Mitosis and Meiosis produce fresh cells. These are as nature, based on their parent’s cells genes.
- Both are ways in which cells reproduce.
- In both Mitosis and Meiosis, DNA gets duplicated.
What is the process of Mitosis?
The process of Mitosis is the form where the cell division happens. Where the cell divides and that too into two new cells, each new cell is identical to the original cell.
What is the process of Meiosis?
Meiosis is the process where the cell gets divided. And then they get divided into four cells. And each of these divided cells has half of the chromosomes from the original cell.
Are Mitosis and Meiosis different or similar in nature?
Mitosis and Meiosis are the different processes that are types of cell division. But there are certain attributes in both that are similar.
In conclusion, both Mitosis and Meiosis are the type of cell division. But how they divide the cell is similar and as well as a bit different in nature too.
