Which specific gene-editing tool is being used in current research to modify the Asian elephant genome for de-extinction efforts?
Answer
CRISPR
The scientific endeavor to resurrect traits of the woolly mammoth involves precise manipulation of the genome of its closest living relative, the modern Asian elephant. Current projects aimed at creating a cold-resistant, mammoth-like hybrid rely heavily on advanced molecular biology tools. Specifically, researchers are attempting to utilize gene-editing technology known as CRISPR. This tool allows scientists to target and incorporate specific mammoth genes—such as those responsible for traits like thicker hair, smaller ears, and enhanced cold tolerance—directly into the existing DNA structure of the Asian elephant cells.
