What is Mirror Bacteria?

Recent developments in synthetic biology have raised alarms among scientists regarding the creation of “mirror bacteria,” which refers to synthetic organisms with molecular structures that are the opposite of those found in nature. A group of 38 scientists from nine countries has brought to light the unprecedented risks these organisms could pose to humans, animals, and plants.

About Chirality

Chirality refers to the property of asymmetry in molecular structures. All known life forms possess specific handedness in their molecules. DNA and RNA consist of “right-handed” nucleotides, while proteins are composed of “left-handed” amino acids. This handedness is crucial for molecular interactions and biological functions.

Potential Risks of Mirror Bacteria

The creation of mirror bacteria would disrupt the natural molecular design. These synthetic organisms could introduce harmful pathogens, leading to unpredictable consequences for ecosystems and health. The scientists argue that the risks associated with mirror bacteria are largely overlooked and require immediate attention.

Scientific Concerns and Recommendations

Initially, some scientists were sceptical about the dangers of mirror bacteria. However, they have since acknowledged the potential for catastrophic outcomes. Jonathan Jones, a report author, emphasised that while the likelihood of failure may seem low, the repercussions could be severe. The report recommends halting research on mirror bacteria unless compelling evidence suggests otherwise.

Funding and Oversight

The report, spanning 300 pages, discusses the feasibility and hazards of mirror bacteria. Some laboratories and funding bodies are exploring these synthetic organisms for vital information about biology and drug development. Nonetheless, the scientists advocate for stringent oversight and caution against funding projects that aim to create mirror life, citing the risks as outweighing potential benefits.

GKToday Notes:

1. Mirror Bacteria: Synthetic organisms with reversed molecular structures pose unprecedented risks. They threaten ecosystems by potentially introducing harmful pathogens, disrupting natural biological functions and interactions.
2. Chirality: Chirality is the property of asymmetry in molecular structures. It determines the handedness of molecules, essential for biological interactions. DNA and proteins exhibit distinct chirality, crucial for life.
