There Is A New Discovery Of The Origin Of Life, There Are Possibilities That DNA And RNA Occurred At The Same Time.
A new study by chemists from the Institute The Scripps (T S R I) has offered an alternative explanation of the origin of life on Earth. A study published in the journal Angewandte Chemie adds novelty to the hypothesis of an R N A world, suggesting that the R N A and D N A may be developed at the same time.
Scientist Ramanarayanan Krishnamurthy explains that there is no reason not to take into account the possibility that RNA and DNA were present at the same time.
According to the hypothesis of an RNA world, R N A is formed from a mixture of chemical compounds that were present on Earth 4 billion years ago, and it was the first self-replicating molecules. Then sprung complex molecules such as proteins and enzymes, but ultimately developed and DNA leading to the appearance of a complex life.
RNA and DNA are not really so different. Characterized DNA double helix, while RNA looks like half of these coils.
The transition from RNA to DNA would not be simple that there was no mechanism that kept them apart. Evidence from studies say it is possible that the DNA came long before now consider. futurism Phys
RNA (ribonucleic acid) is very similar to DNA (Deoxyribonucleic acid), but differs from it in a number of important structural details. RNA in the cells consists of a chain while the double stranded DNA (double stranded); while nucleotides R N A make ribose and uracil, DNA consisting of thymine and deoxyribose.
