Our body is collection of different organ working in harmony to carry out this beautiful life…..Each organ is composed of tissue…..different types of tissue makes the organ…..Each tissue is made up of specific types of cells…..
I want to focus more on the cell…..
Cells are the basic unit of any organ system eventually we can say that cells is the basic unit of life….
A particular cells consists of nucleus…which contain chromosomes…In humans we have 46 chromosomes (23 pairs)
What are chromsomes ?
Ahhh….this one is interesting…..
A gene is just like recipe book which has similar function as a book….
A normal recipe book consist of method to prepare a particular dish…..Similarly particular gene consist of code which codes for specific protein in the body….
Story of gene…..
When earth was freshly formed…and water starts to accumulate onto the earth 🌍 …….under favourable condition there is formation of molecule(a body) inside the water……
That body has a property of replicating itself and formed more of itself(clone)….Within few year,there are many such body inside the water…..lots of clone of similar molecule….
Also, when that body was replicating sometime there is error in replication and instead of forming clone….it forms body which is not similar to parent body… Thus, new type of molecule is formed again(new body)….
This new body also starts to replicate forming its clone at the same time forming many new body…which also replicate forming new-new body….
Since there are many different type of molecule inside the water,there starts the competition between those body for survival….Thus, many body develope property of creating substance(protein) which kills the other body and thus by destroying its competitor they survived and start consuming the nutrients around the water…..
Different body got the ability to create different protein which helps in its survival……Thus, inside water there are only those molecule which are fit for survival…and when they replicate they pass their ability(surviving property) to their next generation…..
Now, many different body which are compatible with each other get combined with itself…..By compatible i meant,protein of one body help in survival of other….such body came together and stick to each other….
Now that two body, became one body which replicate to form many of its clone which has property of creating both the protein which helps in their survival…….
And as the environmental condition of earth starts to change, for example,rain,summer, winter etc…..It becomes difficult for those body to survive…..So many different body came together linked with each other inorder to facilitate their survival…..
The total result of all protein produced by a single body(which is combination of different body) has result in the formation of structure which protects those body from the external environment…..Such structure includes the marine plants and animals…..
Those body starts to living inside plants and animal…..and starts to replicate in that structure too…
New plant(structure which contain body) which are formed from previous are somewhat similar with little 🐺different due to error in replication leading to formation of plant which has the property to survive even on the land…Thus those body kept their first step on land inside the plant and animal which are the result of error of replication from marine plants and animals….
And many errors results in the development of body…which we call as humans….Those molecules became more and more advanced and start to formed structure which we now reffered to the human body…..
Thus,human body is nothing but just home for those molecules which protects them from external dangerous envirinment…..
When a human body feels urge to sex is nothing but its a sign that, those molecule want to replicate themselves because they knew that this house is not going to last longer so with the production of offspring they pass themselves to the next house(inside baby) with little bit of variation….
Those body are nothing but the gene.
Basically using our body for their survival….”selfish kahi ka”
