Is there a mathematical relationship between DNA "wobble" and the precession of the poles?

Question

I'm afraid my knowledge of the mathematics of spirals is insufficient for me to answer this on my own, and I've always wondered if there might be a relationship of some kind between the two. I'm asking because I believe life probably originated near the poles (wherever they were back then!) because it is probably the first place on Earth where it would have been cool enough for biological reactions to occur. Please take into account that the modern 26,000 year cycle would probably have been a lot faster billions of years ago when life originated. Thanks to all who answer.

Answer 1

There are a few things that need clarification. Wobble in molecular biology does not mean a physical movement. It refers to a lax base-pairing requirements (not rigid, loose, wobbly) of the 3rd position of the codon in the interaction between mRNA and tRNA. This is due to RNA modification, G-U base pairing and the shape of the active sites of ribosomes.

The precession of the earth's rotation axis has to do with un-balanced rotation and torques applied by the moon and sun. These forces have no bearing at all at the molecular scale.

Why would you think life had to originate near the poles? The development of life (abiogenesis) has two main camps and neither involve cold polar oceans. On the contrary, one of the more promising ideas involve hot, deep sea vents. Lots of biology can occur under extreme conditions. There are bacteria that can live in boiling water, sulfuric acid, buried under glacial ice and even under high radiation exposure.

There is an astronomical cycle that may have periodically impacted life on earth. The orbit of the sun around the Milky Way takes about 64 million years to complete. The orbital plane is inclined so some times the earth is above or below the plane of the galaxy. Every 62 million years or so, we see a mass extinction recorded in the fossil record. It could be coincidental. Or it could be due to the loss of protection from the galactic magnetic field and the increased radiation from the Virgo Supercluster might have had a sterilizing effect.

Answer 2

I'm not sure if you quite understand the wobble effect. The wobble effect is the idea that multiple sequences transcribed onto mRNA (codons) can be translated into the same amino acid. The reason for this is that a codon is made up of 3 bases, each of which can have one of four different "flavors." This means that there are 64 different kinds of combinations. Meanwhile, there are only 20 enzyme types available to attach the amino acids. Therefore, there's overlap. In short, the wobble effect is a result of the varieties of enzymes in existence. It has nothing to do with the "precession of the poles."

Answer 3

"wobble" refers to the phenomena observed in tRNA codons. During wobble, the first and second base positions stay the same but the third base in the codon is referred to as the wobble position, because it can vary between complementary bases during protein synthesis. I don't see how this relates to the north or south pole, then again I am not very creative. Sorry, good luck.
