Cell cycle and Cell division

By | August 31, 2021

All the living organisms, even the enormous ones, start their journey from a single cell. The process through which cells originate from existing living cells is called as cell division. Each cell have the ability to divide into two daughters cells (In mitosis), which again can grow and divide. This after many cycles (of growth… Read More »

Differences between DNA and RNA

By | August 21, 2021

Nucleic acids accounts for one of the four major biological macromolecules, which carry genetic blueprint of a cell and are essential for proper functioning of the cell. Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA) are two important nucleic acids which help in carrying genetic information and are made up of nucleotide monomers. Even though both… Read More »

What are prokaryotes ?

By | August 18, 2021

All the living organisms on this planet are made up of cells. They can be divided into two groups : Prokaryotes and Eukaryotes. Prokaryotes are single celled or colonial organisms, where the cell is surrounded by cell membrane or plasma membrane and lacks a defined nucleus (as found in eukaryotic cell). These cells are of… Read More »

Anabolism – Building cell structures with simple molecules

By | August 7, 2021

Every living creature on this planet Earth needs to extract energy from the dietary food, a process termed as Catabolism ( breaking down of complex molecules into simpler molecules to yield maximum energy, eg: Glucose gets converted by a process involving Glycolysis, Krebs cycle and electron transport chain – to yield ATP). The opposite cellular… Read More »

4 major Biological Macromolecules – Fueling Life

By | July 27, 2021

Everything on this Earth – living and non-living, is made up of atoms. An atom is the smallest unit of matter that has the characteristic properties of a chemical element. Two or more different or similar atoms will combine to form “Molecules” with the help of chemical bonds. Many molecules, joined together in an organized manner… Read More »

DNA – Instructions for life

By | July 21, 2021

If one looks inside the nucleus of every human cell, there are 46 tiny rod like structure called as Chromosomes. These chromosomes are made of tightly coiled strands of Deoxyribonucleic acid – DNA. It is one of the two main nucleic acids found in our cells. DNA happens to be the genetic material in all living… Read More »

What makes a human body ?

By | July 10, 2021

Every living thing on this planet is made of almost similar components. The smallest functional structure found in all living organisms ranging from basal micro organisms like bacteria to highly evolved human body, happens to be a “Cell”. In multicellular organisms there are different kinds of cells, each performing a special function. They have the… Read More »

What is Epigenetics?

By | June 29, 2021

Genes and behavior Even though identical twins come from the same genetic material, they turn out to be very different people looking alike. So different that one of the twins could get a genetic disorder at the age of 40 and the other could be the most fit person! Why is that so? Epigenetics: The… Read More »
