How can mitosis cause cancer?

-
Have you ever thought about mitosis causing cancer? Well,first of all,mitosis is the most common form of cell division that helps in growth and repair. During mitosis,the cell makes an exact copy of itself and splits itself into two daughter cells. It is generally controlled by the genes inside the cells. But sometimes,this control can go wrong.
If this happens in just a single cell,it can replicate itself to make new cells that are also out of control. Well,these mostly are,cancer cells.
Without the control systems that normal cells have,they replicate rapidly. Tumors or lumps are formed by cancer cells that damage the surrounding tissues. Sometimes,these cancer cells may break off from original tumor and spread in the blood to other parts of the body.

UNDERSTANDING AN ADOLESCENT'S BRAIN- IS IT ACTUALLY SIMPLE?

Image Source: https://movingscience.dk/infographic-about-the-adolescent-brain-development/ It really doesn't matter how smart an adolescent is, or how well they scored in NEET/JEE/SAT or whatever. Adolescence is a remarkable phase of human development, often marked by a unique blend of curiosity and self-discovery. I know it's been really long since I have posted here, and one of my friends wanted me to write on how an adolescent's brain behaves so distinctly compared to kids and adults- and so this is for her and for everyone else sitting with their curious caps on! The adolescent brain is a dynamic landscape of neuroplasticity, where synapses are pruned and rewired to optimize cognitive function. This plasticity not only facilitates learning, but also paves the way for development of higher-order thinking and decision making. A rapid increase in the connections between the brain cells also occurs, which makes the neural pathways more effective.  For both boys and girls, a

CAN TWO EGGS BE FERTILISED TO FORM A ZYGOTE?

  So, one of my friends asked me this brilliant curious question one day - Instead of a sperm fertilising an egg, can an egg fertilise another egg? So, this post is mainly for her and many other inquisitive people out there wondering similar things. I have been having so many thoughts on this and the following is a small gist of my thoughts penned down.  So let's say one were to take an egg, insert the DNA from another egg, and then insert centrosomes from another cell, is it possible for the cell to divide? Well, probably we might have to give it a mild electric shock. This is what is done in some cloning techniques. I mean, of course, there is no guarantee that this method is bound to work, but probably it might work?  Replication can be done in the lab too but the issue is that there is not much understanding about gene regulation and reproduction. Most of us know about Dolly, the sheep which was the first mammal to be cloned, using the diploid nucleus from an adult tissue. Here

DOES MUSIC MOVE YOU? HERE'S THE ACTUAL REASON WHY IT HAPPENS!

For all the music lovers, this post is especially for you all! Imagine a day without music- a world where melodies don't grace our ears, and rhythms don't resonate within our souls. From the soothing cadence of a lullaby to the pulsating beats of an adrenaline-filled anthem, music has an unparalleled ability to mold our emotional landscapes and shape our mental well-being. Even some nearly non-communicative people with Alzheimer's disease sing along and engage in conversations when the music they have listened to the most, during their childhood days, is played.  Let's actually explore the reason why and how music moves us so much! When you listen to music, it is basically like a power-up for your brain! It's like a surge of energy zipping through your mind. When you tune in, your brain gets a boost- the
