Molecular evolution

When a neurone fires, it sends an electrical signal that jumps down the axon via the nodes of Ranvier very rapidly. At a synaptic junction, chemical Brownian diffusion signalling with receptor... more

The original question was to predict the basic requirements for information storage. Then the discussion moved to why is it necessary to include mRNA in the protein translation process. Why can't... more

I know this sounds a lot like chicken and egg question and while the latter has an answer, I am intrigued about the former.A modified form of the question would be, in the course of abiogenesis,... more

The question of complexity is classic in the very first lectures of evolutionary biology where the teacher usually tries to tell the students that complexity does not necessarily increase and that... more

Much of the literature for laypeople seems to consider (and to spreadthe idea) that an animal (or a plant, I guess) is characterised by itsgenome. I do not know whether the same goes for more... more

I am currently reading from Chapter 15 in Principles of Life, 2nd Edition:>Many gene duplications affect only one or a few genes at a time, but in some cases entire genomes may be duplicated.... more

Why is ATP the most prevalent form of chemical energy storage and utilization in most cells?
