RNA World 2
Storyboard Text
- The last question is, without enzymes, how could polymer replication have occurred?Template directed synthesis is the theory behind this. DNA replication and transcription are currently catalysed by this mechanism. Free nucleotide strands would have been weakly attracted to replicating strands in an RNA world, allowing for base pairing. If the strands had been attatched to clay, the process could have been sped up.
- Following that, a random synthesis of RNA molecules is proposed. These folded to operate as RNA dependent RNA polymerases.These would have eventually developed into RNA polymerase ribozymes, which would have accelerated the replication process.Scientists seeking to recreate early Earth conditions in research have evolved a number of RNA machines that may have been created in the past.
- Thanks Mya! You sound like you really know what youre talking about
- Whewww... I am tired from all that talking
- How does she run so fast?!?!
