What is CRISPR?
CRISPR (clustered regularly interspaced short palindromic repeats) is a family of DNA sequences found in the genomes of prokaryotic organisms such as bacteria and archaea. These sequences are derived from DNA fragments of bacteriophages that had previously infected the prokaryote. They are used to
detect and destroy DNA from similar bacteriophages during subsequent infections. CRISPR technology is a simple yet powerful tool for editing genomes. It allows researchers to easily alter DNA sequences and modify gene function. Its many potential applications include correcting genetic defects, treating and preventing the spread of diseases and improving crops. |
What is China?
China, officially the People's Republic of China (PRC) is a country in East Asia. It is the world's most populous country, with a population of around 1.4 billion in 2019. Covering approximately 9.6 million square kilometres, it is the world's third or fourth-largest country by area. Governed solely
by the Chinese Communist Party (CCP), the state exercises jurisdiction over 22 provinces, five autonomous regions, four direct-controlled municipalities (Beijing, Tianjin, Shanghai, and Chongqing), and the special administrative regions of Hong Kong and Macau. China is a unitary one-party socialist republic, and is one of the few existing nominally socialist states. Political dissidents and human rights groups have denounced and criticized the Chinese government for human rights abuses, including suppression of religious and ethnic minorities, censorship, mass surveillance, and their response to protests, notably in 1989. |
