Genome editing is a group of technologies that give scientists the ability to change an organism's DNA. These technologies allow genetic material to be added, removed, or altered at particular locations in the genome. It is used in research to understand diseases and in developing gene therapies.
CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) is a powerful gene-editing tool that allows precise modifications to DNA. It was adapted from a natural defense mechanism found in bacteria. CRISPR-Cas9, a specific system, gained prominence in the early 2010s for its efficiency and accuracy in cutting DNA.
Cellular circuits refer to engineered biological pathways within cells that can perform specific functions, similar to electronic circuits. These circuits involve manipulating genes and proteins to control cellular behavior, such as sensing environmental cues or producing therapeutic molecules. They are a key area in synthetic biology.
Examiners frequently ask about the principles of gene editing, key technologies like CRISPR, their applications in medicine and agriculture, and associated ethical concerns. Focus on the 'what, why, and how' of these scientific breakthroughs.
Remember 'GENE' for 'Genome Editors New Era'. These new tools are ushering in a new era of genetic manipulation.
