Life. A mess…

Life is built with three major components: RNA and DNA – the genetic code – and proteins, the cells that carry out their instructions. Most likely, the first cells had all three pieces. But first, RNA, DNA or proteins had to form without their partners. One common theory, known as the “RNA World” hypothesis, proposes that because RNA, unlike DNA, can self-replicate, that molecule may have come first. Some scientists believe the process of its formation may not have been such a straightforward path.

In a paper published in the Journal of the American Chemical Society, Szostak Kim and colleagues present a new model for how RNA could have emerged out of a mixture of nucleotides with similar chemical structures: arabino- deoxy- and ribonucleotides (ANA, DNA, and RNA). Kim found that the chimeric oligonucleotides – like ANA and DNA – could have helped RNA evolve the ability to copy itself. (1)

Can the fish exist without the sea?

– Hi.

– Did you have breakfast?

– No, there were no fish…

Explanatory Notes

  • The “fish without the sea” is a mention to the idea that for something to exist, it may need a medium which has nothing to do with that something. The fish do not need fish to exist, they need the sea.
  • Breakfast is a reference to Jesus last meeting with the Apostles.
