You’ve probably heard of the human genome, the huge collection of genes inside each and every one of your cells. You probably also know that we’ve sequenced the human genome. But what does that actually mean? How do you sequence someone’s genome? Let’s back up a bit. What is a genome? Well, a genome is…
The set of mechanisms that regulates the passage of substances like the ions and small molecules through the cell membrane or the plasma membrane, refers to as membrane transport. The plasma membrane being semipermeable in nature allows certain solutes to pass through while denies the passage for some others.
The only way to make new cells is by duplicating the existing cells. During the process of cell division, the cell duplicates its content and then divides into two. This process of duplication and division is known as the cell cycle. Before the actual division takes place the cell goes through an inter-phase that consists…
Deoxyribonucleic acid (DNA), the genetic material for most of the living organisms, duplicates itself before the cell division by the process of cell division. This animation briefly explains the process of DNA replication, that involves enzymes like the Helicase, Primase, DNA polymerase, Exonuclease and DNA ligase. It also talks about the leading and the lagging…
The information stored in the DNA is decoded by the process of transcription and translation and results in the formation of the polypeptide chain or the protein, a very important and essential biomolecule in any living organism. This video provides a broad and clear picture of the process of gene expression with the help of…
