When we see a beautiful car that charms our desire to have it, we are looking at a creation of electronics, metallurgy and artwork that is designed for our comfort and size of our pockets. The beautifully designed aerodynamic pieces of art, invites us to give it a try, and with permission from our pockets, we will soon be enjoying it. Relishing in its splendor and grandeur and cruising through the galleries of our imaginations. We are gratified regardless of its origin.
But do you know the car could have originated from Australian iron-ore dust? Oh, forget it, you are not in ancestries and have an enjoyable day. Hey, what about you? What are you made of? We are constructed of billions of cells that give us shape and our beautiful texture. Every part of us is an architectural design whose foundations are the cells. Hi, that’s good we are cellular.
In the nucleus of each cell, there are DNA molecules packed into thread-like structures called chromosomes. Each chromosome is made up of a DNA tightly coiled many times. The chromosomes give the cells their function and structure. May I ask: Who are these DNA’s that are basics of our structures?
DNA, or deoxyribonucleic acid, are the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus, but a small amount of DNA can also be found in the mitochondria. Mitochondria are structures within cells that convert the energy from food into a form that cells can use. I get it, so we are all DNA’s and the food we eat, the DNA has a slice also. Well, it is not as simple as that.
Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure. Each chromosome is a single molecule of DNA. In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Chromosomes structure carry hereditary biological information from parent to its offspring. The offspring may or may not enhance the information as it relegates it to its sub-offspring. The biological information that is hereditary is in forms of genes which are a substructure of DNA’s. Remember, bacterium which are disease carriers have DNA’s also. A full set like their victims, unfortunate humans.
A gene is a length of DNA that codes for a specific protein or function. So, for example, one gene will code for the protein insulin, which is important role in helping your body to control the amount of sugar in our blood. Out of all millions of genes in our DNA closet, we only use 3%. Remember the DNA are also in other organism and they may be utilizing another percentage of the genes.
The cells assemble to form different organs in your body as per the instructions from genes or as conveyed by enzymes. From a single strand of a hair to a whole foot, these are all bundles of chromosomes rich cells at work. Each and every one of them communicates through relays that will be a subject of later discussions. You inherited all this structures from your parents and you are at liberty to distribute them. Please, do so.
The reason we are here standing as humans is because our genes and cells have been improving generations after generations. From tiny tadpoles a billion year ago to a robust wide thinking chromosome packed being. This has been possible because of improving environmental conditions and the inquisitive nature of full grown creatures which influence the next set of siblings. No, I heard you, genes and DNA were not created from soil. Yes, I heard you: A good meal and a fight with your neighbor may improve your genes.
