Mitosis _ Cell Division

Omnis Cellula e cellula.  This statement from a man named Rudolf Virchow changed the entire outlook of biology and how organisms funtion. How our body functions. This statement must have clearly baffled your brain, more likely to think it as gibberish. But don't worry. If your brain declares this as Greek and Latin, congratulate it, as it is right. Ironically it is Latin. It basically means:- "Every new cell arises from old ones" And in this blog, we will see how this german scientist 's Latin statement shook the Biology world in English. 😜 But before we begin, we need to learn the meanings of few basic terms which will be repeated throughout the blog Common terms and Definition :- 1) Chromosomes :- These are the cell organelles which contain the genetic material.  2) Chromatin :- This is the network inside the cell nucleus which contains the DNA material. The chromatin network condenses to form Chromosomes when dividing.   3) Centromere and sister chromatids :- A

Trends in the Modern Periodic Table_What does it tell us?

  First, Before we talk about anything else , we need to clear this one thing up  ...What is the Periodic Table? Periodic Table may be defined as the arrangement of all the known elements according to their properties in such a way that the element of similar properties are grouped together in a tabular form. Its a periodic representation of all the elements, in a table ( But, you will be surprised by the amount of information the scientist were able to pack in one chart! )  *The Periodic Table is divided into 1) 18 vertical columns , also called Groups  2) 7 horizontal rows , also called Periods 3) Its divided into 4 blocks (namely s,p,d and f) -- This tells us about the electronic configuration of the element , the subshells or orbitals present in the orbits If you are wondering what "s, p ,d and f" orbital is:- Within the shells, electrons are further grouped into subshells of four different types, identified as s, p, d, and f in order of increasing energy. We can think o
