Summary
Genetic code engineering expands protein synthesis by reassigning codons to unnatural amino acids. Understanding evolutionary history informs laboratory efforts to create designer cells and novel life forms.
Area of Science:
- Molecular Biology
- Synthetic Biology
- Evolutionary Biology
Background:
- The standard genetic code translates mRNA codons into 20 canonical amino acids.
- The genetic code evolved from a primitive form, with reconstructions based on current features.
- Genetic code engineering is a recent field aiming to expand coding capacity.
Purpose of the Study:
- To assess the relevance of evolutionary scenarios for laboratory-based genetic code reassignments.
- To review current genetic code engineering approaches in light of theoretical evolutionary studies.
- To explore the potential of integrating evolutionary theory with experimental concepts for future applications.
Main Methods:
- Review of current genetic code engineering attempts.
- Analysis of theoretical works on the natural history of the genetic code.
- Focus on hypothetical scenarios of codon reassignment during evolution.
Main Results:

03:06From DNA to Protein
The flow of genetic information in cells from DNA to mRNA to protein is described by the central dogma, which states that genes specify the sequence of mRNAs, which in turn specify the sequence of amino acids making up all proteins. The decoding of one molecule to another is performed by specific proteins and RNAs. Because the information stored in DNA is so central to cellular function, it makes intuitive sense that the cell would make mRNA copies of this information for protein synthesis...

The central dogma explains the flow of genetic information from DNA nucleotides to the amino acid sequence of proteins.
RNA is the Missing Link Between DNA and Proteins
In the early 1900s, scientists discovered that DNA stores all the information needed for cellular functions and that proteins perform most of these functions. However, the mechanisms of converting genetic information into functional proteins remained unknown for many years. Initially, it was believed that a single gene is...

03:21Genome Size and the Evolution of New Genes
While every living organism has a genome of some kind (be it RNA, or DNA), there is considerable variation in the sizes of these blueprints. One major factor that impacts genome size is whether the organism is prokaryotic or eukaryotic. In prokaryotes, the genome contains little to no non-coding sequence, such that genes are tightly clustered in groups or operons sequentially along the chromosome. Conversely, the genes in eukaryotes are punctuated by long stretches of non-coding sequence.
