CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) is a revolutionary gene-editing technology that allows for precise modification of DNA sequences in living organisms. It has transformed fields such as medicine, agriculture, and biotechnology by enabling targeted genetic alterations.

A microorganism (microbe) is an organism of microscopic size that typically requires a microscope to be seen. Microorganisms encompass cellular life forms such as bacteria, archaea, many fungi and protists, as well as acellular infectious agents like viruses (often studied in microbiology though not considered living). They inhabit nearly every environment on Earth and play essential roles in ecosystems, industry, and human health.
