Czech and Indian Advances in Faunal DNA: Tiniest Codes have Big Consequences

By the end of the 20th century DNA had ceased to be an abstract phrase in the laboratory and had become an everyday key to life, the code that biologists read, edit and, increasingly, conserve. At its simplest a genome is a long string of information; in bacteria much of the short-term adaptability depends not on the chromosome but on small circular molecules called plasmids, which bacteria copy independently and exchange with one another. These tiny rings carry genes that can make the host microbe resist antibiotics, digest new foods, or survive a sudden stress, and because they are mobile, plasmids are central to both microbial evolution and the same techniques molecular biologists use to move DNA around in the lab.

That basic understanding, how DNA is stored, copied and sometimes borrowed, is exactly the toolset that has produced recent breakthroughs from the Czech Republic. In one line of work, structural biochemists at the University of South Bohemia resolved, at near-atomic detail, a protein motor that slides along DNA and drags it into a protein nanomachine; the finding, a long-sought explanation of a molecular apparatus, could deepen our understanding of how bacteria rewrite their genomes and, eventually, inform ways of limiting antibiotic resistance.

In another striking discovery from the Czech Republic, molecular parasitologists described a previously unknown protozoan, given the name Blastocrithidia nonstop, whose genome reads the genetic code in a way that defies textbook expectation. The organism packs thousands of conventional stop codons inside genes, yet its ribosomes do not stop; instead, special tRNA and protein adaptations allow the reading machinery to continue and to assign amino acids where other organisms would terminate synthesis. For geneticists and synthetic biologists this is not just curiosity: it is a window into alternate ways of encoding and decoding information, and into evolutionary creativity that challenges the universality of the genetic “grammar”. The work, led by teams at institutes of the Czech Academy of Sciences and published in a leading journal, expands how biologists think about what a genome can be.

Those advances from the Czech Republic, one structural and one genomic, have two things in common. First, both depend on precise molecular knowledge: of motors and of translation, of enzymes and of tRNA modifications; second, both suggest applications that reach well beyond the immediate lab bench, from novel antimicrobial strategies to new tools for synthetic biology. This is also where a different set of institutions, on another continent, in India, has been building complementary capabilities: repositories, applied genetics for conservation, and the administrative systems needed to turn genetic knowledge into field action.

India’s recent steps are instructive in their scale and ambition. In the Himalayas, the Padmaja Naidu Himalayan Zoological Park in Darjeeling has become the site of India’s first zoo-based biobank, a “frozen zoo” that stores genetic material from endangered Himalayan species. Operating since mid-2024, the facility collects and cryopreserves tissue, cells, and other genetic material at very low temperatures so that the genetic blueprints of animals such as the red panda and snow leopard can survive habitat loss, poaching and demographic collapse. For conservationists, such a biobank is not an answer in itself but an insurance policy, a way of buying time and options for assisted reproduction, disease research and genetic rescue.

If the Darjeeling biobank preserves whole animals’ genetic legacies, Indian genetics has long been active at the molecular level too. Lalji Singh — the scientist often described as the father of DNA fingerprinting in India — established institutions and practices that brought DNA into courts, clinics and conservation laboratories. Singh founded the Centre for DNA Fingerprinting and Diagnostics and, important for conservation genetics, the Laboratory for the Conservation of Endangered Species (LaCONES) in the late 1990s; LaCONES went on to develop assisted reproductive techniques, species recovery methods and forensic protocols that translate DNA knowledge into species protection. His career is an explicit reminder that the same molecular tools that solve crimes can also help save species.

Beyond personalities and single facilities, India maintains national infrastructure that makes genetic and microbial research possible at scale. The Microbial Type Culture Collection and Gene Bank (MTCC) in Chandigarh, a national repository established in the 1980s and housed at CSIR’s Institute of Microbial Technology, preserves thousands of authenticated microbial strains, serves as India’s International Depositary Authority under the Budapest Treaty, and supplies cultures for research, industry and patenting. The MTCC’s work is the quiet, indispensable record-keeping of biotechnology: it keeps reference strains alive, checks viability and preserves plasmids, bacteria and fungi so that experiments and biotechnological products can be reproducible and legally secure.

Science and conservation are never only about labs and repositories. They are also about policy and partnerships that let knowledge move, including funds, personnel, reagents and data, across borders. India and the Czech Republic have signalled intent to deepen cooperation in health, science and allied areas, reaffirming that diplomatic instruments can accelerate joint projects that range from microbial genetics to conservation medicine. Such bilateral ties matter when, for instance, an unusual genetic mechanism discovered in Prague suggests a line of enquiry that requires diverse microbial collections, or when conservation geneticists in India seek comparative genomic expertise. The match is not automatic, but the framework is now visible.

Taken together the Czech and Indian stories sketch a pattern worth holding to: foundational molecular knowledge (how plasmids move and how ribosomes sometimes re-read stop codons) and institutional capacity (biobanks, culture collections, conservation labs) are two sides of the same coin. One reveals how life encodes and edits itself; the other preserves those encodings for study, management and, when necessary, intervention. In practice this means labs in the Czech Republic resolving molecular machines and parasites that rewrite genetic expectation, and Indian institutions preserving species’ genomes, providing forensic and assisted reproduction capability, and housing the microbial libraries that underpin biotechnology.

For the researcher, the policymaker and the citizen, the takeaway is pragmatic: understanding DNA’s mechanisms is only part of the task; the rest is creating trustworthy, long-term stores of biological material and building cross-institutional bridges so that discoveries can become diagnostics, conservation actions or safer medicines. Work from the Czech Republic teaches us about the possible; the Indian infrastructure teaches us how to hold the possible in reserve until it can be used. Together they make a practical architecture for twenty-first century biology — local expertise and global stewardship, results and repositories, microscopes and samples preserved in cold storage.
