Order and disorder: Ecological adaptations not mutations

In the context of order and disorder that includes what is known about quantum physics and light-induced amino acid substitutions in plants and animals, as well as the control of the functional rearrangement of influenza hemagglutinin, I’m beginning to see even…

Conserved microRNA editing

Conserved microRNA editing in mammalian evolution, development and disease Excerpt:  “…site-specific miRNA editing is an evolutionarily conserved mechanism, which increases the functional diversity of mammalian miRNA transcriptomes.” Excerpt 2): “…miRNA editing is an integral and evolutionarily stable feature of mammalian…
