What is CRISPR technology, recently seen in news?

A. An element-editing tool

B. A gene-editing tool

C. A video-editing tool

D. None of these

Explanation:

Scientists have unveiled the detailed genome of the malaria mosquito vector, revealing thousands of new genes vital for the development of genetic control strategies of disease transmission. In order to engineer advanced forms of defence against malaria transmission, including targeted CRISPR and gene drive–based strategies, scientists require intricate knowledge of the genomes of vector mosquitoes. CRISPR technology is a gene-editing tool which allows researchers to easily alter DNA sequences and modify gene function.
