Summary
The proposed 3 31 nt minihelix tRNA evolution theorem offers a proven theory for biological sciences, explaining tRNA and genetic code coevolution and the origin of life. This model falsifies alternative theories.
Area of Science:
- Origin of Life research
- Molecular Evolution
- Biochemistry
Background:
- Biological sciences currently lack universally accepted theorems.
- Transfer RNA (tRNA) molecules are central to protein synthesis and genetic code translation.
- Understanding tRNA evolution is key to deciphering the origin of life.
Purpose of the Study:
- To propose and validate the 3 31 nt minihelix tRNA evolution theorem as a foundational theory in biology.
- To elucidate the coevolution of tRNAomes and the genetic code.
- To establish the chemical evolutionary history of life based on tRNA.
Main Methods:
- Statistical analysis of tRNAome sequences.
- Comparative analysis of tRNA structures and evolutionary pathways.
- Falsification of alternative tRNA evolution models (2 minihelix, convergent, accretion).
Main Results:
- The 3 31 nt minihelix theorem accurately describes Type I and Type II tRNA evolution from ordered RNA precursors.
- Statistical tests provide overwhelming support for the theorem.
- The theorem links tRNA evolution to the origin of life and genetic code development.
- Alternative models for tRNA evolution were falsified.
Conclusions:
- The 3 31 nt minihelix tRNA evolution theorem should be universally accepted as a biological theorem.
- Ribozyme-mediated RNA ligation was a crucial driver in early life's chemical evolution.
- tRNA served as the foundational core for the evolution of Earth's living systems.

One of the unique features of tRNA is the presence of modified bases. In some tRNAs, modified bases account for nearly 20% of the total bases in the molecule. Altogether, these unusual bases protect the tRNA from enzymatic degradation by RNases.
Each of these chemical modifications is carried by a specific enzyme, post-transcription. All of these enzymes have unique base and site-specificity. Methylation, the most common chemical modification, is carried by at least nine different enzymes, with...

25.4K
The large ribosomal subunit has several important structures essential to translation. These include the peptidyl transferase center (PTC) - which is the site where the peptide bond is formed - and a large, internal, water-filled tube through which the nascent polypeptide moves. This latter structure is called the Peptide Exit Tunnel, and it begins at the PTC and spans the body of the large ribosomal subunit. During translation, as the nascent polypeptide chain is synthesized, it passes through...

28.3K
RNA polymerase (RNAP) carries out DNA-dependent RNA synthesis in both bacteria and eukaryotes. Bacteria do not have a membrane-bound nucleus. So, transcription and translation occur simultaneously, on the same DNA template.
Transcription can be divided into three main stages, each involving distinct DNA sequences to guide the polymerase. These are:

The basic structure of RNA consists of a string of ribonucleotides attached by phosphodiester bonds. Although most RNA is single-stranded, it can form complex secondary and tertiary structures. Such structures play essential roles in the regulation of transcription and translation.
Different Types of RNA Have the Same Basic Structure
There are three main types of ribonucleic acid (RNA) involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). All three...

Unlike eukaryotes, bacteria use a single RNA Polymerase (RNAP) to transcribe all genes. The different subunits of bacterial RNAPhave distinct functions. The multisubunit structure of the bacterial RNAP helps the enzyme to maintain catalytic function, facilitate assembly, interact with DNA and RNA, and self-regulate its activity.
In most genes, the transcription site is a single base present upstream of the coding sequence. Though RNAP is a catalytically efficient enzyme, it does not recognize...

Aminoacyl-tRNA synthetases are present in both eukaryotes and bacteria. Though eukaryotes have 20 different aminoacyl-tRNA synthetases to couple to 20 amino acids, many bacteria do not have genes for all of these aminoacyl-tRNA synthetases. Despite this, they still use all 20 amino acids to synthesize their proteins. For instance, some bacteria do not have the gene encoding the enzyme that couples glutamine with its partner tRNA. In these organisms, one enzyme adds glutamic acid to all of the...
