A similar property of synthetic E. coli, according to a professor at the Laboratory of Molecular Biology
Scientists have modified the genetic codestandard bacterium E.coli. It is noted that the genetic code of any cell is encrypted using codons - trinucleotide units in DNA or mRNA that encode a specific amino acid in protein synthesis. However, scientists have found that many cells have extra codons responsible for adding the same amino acid.
During work, the authors replaced all repetitions in itTAG stop codon on TAA. Similarly, scientists reduced the number of codons coding for the amino acid serine. After such an operation, the bacterium continues to live, but becomes invulnerable to viruses, since the modified organisms simply do not have the genes to read them.
If the virus gets into vats of bacteria,used to produce certain drugs, it can destroy the entire batch. Our modified bacterial cells can solve this problem by being completely resistant to viruses,” said project leader Professor Jason Chin in a press release from the UK Research and Innovation Authority (UKRI).

This property of synthetic E.coli, according to Professor Chin, makes it especially attractive for the production of various drugs and reagents for the chemical industry.
