DNA or RNA structure about life

Lets study about DNA and RNA to know the details that from where the life has came from.
When the first self-replicating organism was formed its molecule was made up of RNA , a close cousin of DNA . RNA(ribo oxy nucleic acid) is a single strand nucleic acid made up of phosphate ,ribose sugar and nitrogen base. The idea has always had a huge problem , though there was not even a chance of formation of RNA molecules from primordial earth. And if RNA molecules couldn’t form spontaneously, how could self replicating RNA molecules arises ? did some other replicator come first? If so, what was that? The answer was really twisting the question.
When biologist jump into the question that how life arose? This question seems to be more baffling… today what all are the organisms we see around us is because of the hard work of protein . proteins can twist ,fold itself into wild diversity of shapes, they can also perform as enzymes also. Protein also help in the catalysing(speed up) the chemical reaction in the body of living organism. Whatever it is but the information which are used in making protein is stored in DNA molecules so we cann’t make new protein without DNA and even we can not make new DNA without protein so now the question is that who came first DNA or protein?
The discovery in the 1960s that RNA could fold like a protein , albeit note such complex structures , suggested an answer . if RNA could catalyse reactions as well as storing information , so some RNA molecules might have capable of making more RNA molecules. And if that was the case , then RNA replicators would have had no need for proteins. They could do everything by themselves.
It was an good imaginary idea but at that time no one shows that RNA could catalyse reactions like protein enzymes until 1982, after many researches it RNA enzymes were discovered in Thomas cech of the university of Colorado in boulder found it in tetrahymena thermophile ,a bizzare single- celled animal with seven sexes.
People start discovering more RNA enzymes in the animals and even created in labs so this proves that RNA does not need protein for further its catalysis process so now the question arises what is the use of protein in the RNA?? It is believed that RNA is the first complex molecules of life.
There are many question about RNA still disturbing people a lot one of it that RNA hypothesis give an evidence that the elements like boron, molybdenum and oxygen these are essential for the initial production of RNA molecules. But this is found more abundant in mars than the earth so something might wrong have happened to mars that life can not rose up in mars so that’s why scientist believe that the life might have come from extraterrestrial origin through meteorite near mars. And they called it as meteor ejections.
Now a day’s RNA is replace by DNA (deoxyribonucleic acid) which is evolved through RNA . as per of of the Darwin theory of natural selection that a organism can only survive in the environment if its body is adaptive to the changing natural condition . the early earth condition are not similar to right now condition so the organism have capability to self replicate itself to evolve their shape ,size ,metabolic activity and even reproduction.
The complexity of chemical reaction give rise to an life. But the question is how everything in the earth is for living but in other planet it is not? No one knows how to answer this . if I imagine in the scientific way that main root cause of life let we start from the main component of life I,e water so the water is the main component of life. So from where this water came from the answer is that because of heavy rain so the question arises that from where the rain has came from the answer is that rain came from the cloud so now the question arises how the cloud is formed? The answer is that the cloud is formed from the evaporation of water so now the question is that how the evaporation of water takes place ? the answer is the evaporation of water takes place through the heat of sun. so now question arises from what the sun is made from and from where it came from? So the answer will be that it is made up of with the combination of nuclear fusion of hydrogen and helium. And it came from the big bang so now the question arises how the big bang takes place? The answer will be that it is due to instability and fluctuation takes place in particle which causes big bang now the question arises from where the big bang particle came from ? this is the question which most of the scientist can’t answer their head goes down when this question were asked . so this remain as the unsolved mistry. Again what is life ??
