Chicken-Egg Issue Regarding the Origin of Life

There are three different types of chemicals essential for life carbohydrates, proteins, and nucleic acids (DNA/RNA). The duplication of DNA requires an enzyme DNA polymerase among others. DNA polymerase is a protein. However, as outlined above, a protein is produced according to the blueprint on a DNA. So, DNA needs protein(s) for its own duplication, and proteins need DNA as the source of information on their structures. So, in the beginning, which came first, DNA (gene) or protein This is the ultimate chicken-egg issue. 

Some people thought that proteins came first, perhaps without the instruction by a gene, and indeed some proteins have been shown to form spontaneously. One of the problems is this does the protein have a specific seqnence so that it functions in biologically meaningful manners Is not a blneprint (DNA) necessary to make such a specific protein after all These ideas were discnssed and arguments were made when the enzymes that catalyze any bioreactions were considered to be proteins i.e., only proteins can be enzymes. This was a kind of dogma hypothesized or even believed but not really proven. 

In mid-2000, a report came out, which demonstrated in detail that the ribosomal RNA is indeed the site where proteins are formed. t-RNA with an amino acid bound 

Would this study settle the issue of chicken-egg issue once and for all Well, not quite yet. There is an issue about how RNA was created first without organisms. No plausible idea has been put forward about this issue, let alone being proven.
