What is the primary function of an 'intron' in the context of the RNA processing described in the study?

It is a segment of RNA that is removed from a precursor molecule during editing.

It acts as a template for protein synthesis in the ribosome.

It is a permanent structural component of the cell nucleus.

It serves as a courier protein that facilitates viral gene transfer.

Which of the following best describes the phenomenon of 'horizontal gene transfer' as observed in the Max Planck Institute study?

The movement of genes between organisms without the assistance of a viral or external courier.

The transfer of genetic material from parent to offspring through sexual reproduction.

The process by which archaea and bacteria exchange DNA exclusively through cell division.

The mutation of genes within a single organism due to environmental radiation.

Gene transfer research

This research provides scientific context on horizontal gene transfer and biotechnology, which are relevant to GS3 syllabus themes, but it is a fundamental research discovery rather than a direct policy or application-based development likely to be asked as a standalone question.

Notes

Scientists at the Max Planck Institute for Marine Microbiology observed direct horizontal gene transfer of an RNA molecule (intron) across species without a courier.
The study involved a predator ultramicrobacterium, Velamenicoccus archaeovorus, and its prey, the archaeon Methanothrix soehngenii.
Introns are segments of RNA that are cut out during the processing of ribosomal RNA (rRNA) precursors.
The observed intron possesses the ability to self-circularize, which protects it from degradation by cellular enzymes.
Researchers utilized a fluorescent probe to visually track the movement of the intron from the predator to the prey cells.
Horizontal gene transfer (HGT) is a mechanism by which organisms acquire new traits, such as antibiotic resistance or metabolic capabilities, outside of traditional inheritance.
Transposable elements (jumping genes) are known to contribute to the spread of antibiotic resistance and the development of cancers.
Circular RNA molecules derived from introns are being researched as potential platforms for next-generation vaccines.
