I found this very interesting comic online about pizza mitosis. The diagram shows mitosis but with pizza. It shows things like sausage and anchovies as the organelles and it explains the process of them splitting. I think it's a great analogy for cell division.
This article talks about how cells are eating each other in order to prevent nasty tumor growth. The idea behind this is that when cells divide at a rate faster than cells are dying, they can create an abnormal accumulation of extra cells which structurally resembles a lump, and causes cancer. It is suggested that entosis (a process of cell cannibalism) can help slow down cancer.
"Because Mitosis is the division of the nucleus, only organisms that have nuclei can go through mitosis-- so only EUKARYOTE cells can undergo mitosis (unlike prokaryotic cells, such as bacteria, that have no nucleus.
Even though prokaryotes do not undergo mitosis, they also reproduce using asexual reproduction. Instead, prokaryotes divide using a process called BINARY FISSION. In binary fission, the cell duplicates its genetic material. The cell then elongates, causing the genetic material to split, the cell pinches down the middle, producing two new daughter cells, identical to the parent cell."
This chapter of the book informed me the process in which prokaryotes reproduce because that action is essential for species survival

In this article, it says that structural biologists have discovered a key step during cell division that involves a certain type of protein (Ki-67) that may be related to cancer. Using this information, they hope to slow down mitosis that occurs in a tumor.
While listening to Jimin (BTS) - Serendipity, I stumbled upon a lyric that said "I'm your calico cat" and I didn't really understand it. Recently my sister became addicted to the song and told me that calico cats are rare, so I searched it up.
In the article, it tells us why male calico cats are rare. It is because calico cats are not a breed, it just depends on their coat. The X chromosomes carry the genes for the color of a cat's coat, while the Y chromosomes determine the sex of the cat. In order for a cat to have the calico pattern, one of the X chromosomes must carry the black gene and the other X chromosome must carry the orange gene. When chromosomes don't divide properly, a male calico cat is born with an extra X chromosome. When one X chromosome carries the orange gene and the other carries the black gene, and there is a Y chromosome, a male calico cat is born (male calico cats have XXY combination). Abnormal chromosome counts are unusual in cats, but not rare. Only one out of 3000 calico cats are male. However, only one of 10,000 male calico cats can reproduce. An XXY combination can occur in humans as well. This is called Klinefelter syndrome.
So when Jimin says "I'm your calico cat," it means he's a rare boy. He's like one in 7.4 billion. Calico cats are also believed to be lucky, so we're so lucky to have this talented boy on this planet.

The duration of each part of the cell cycle is different for almost all cells. From 8 Minutes, to 2 full years, the cell cycle proves to vary greatly. Nonetheless, it has been shown that the average cell cycle takes a little less than 24 hours with the Synthesis phase usually being the longest stage. On average they will take 10 hours for the G1 phase, from 5 to 6 hours to complete Synthesis and G2 in only 3 to 4 hours in. Therefore, interphase generally takes between 18 and 20 hours. Mitosis then generally takes about 2 hours. This again shows how intricate and different cells can really be.
The cell cycle is a very complex process that involves many different factors to undergo the process. Despite this, Humans know lots about this cycle and its functions, but there was one thing that we didn’t know for a very long time. This was how the cell knows when to begin the G2 phase with the S phase completed. Just recently though, scientists discovered that the cell detects ongoing DNA replication. Thus, sending out a signal that delays the start of the G2 phase, so it can happen with everything needed. Researches believe this discovery may be essential in targeting the growth of cancer cells. This is also very interesting to me because there may be way more things still to learn about the cell cycle and mitosis.
This picture is funny because in mitosis one cell becomes two identical cells and it the picture is looks like one cat is becoming two cats ( they seem to be in Telophase ). The pun of Me-ow-sis is also a funny play on the word mitosis using the word meow.
