Four brown anole lizards (a type of tropical
lizard) have been genetically modified using the CRISPR-Cas9 gene editing tool.
This is the world’s first successful attempt at producing a genetically
The researchers from University of Georgia, USA
had used CRISPR-Cas9 to fertilize the immature eggs of anole lizards and
produce four pink albino offspring.
Scientists are of the opinion that the successful
research would help the study of human medicine, particularly the eye.
Genome/Gene editing is the deliberate alteration
of a selected DNA sequence in a living cell. It involves editing an organism’s
DNA by altering, removing or adding nucleotides to the genome.
CRISPR-Cas9 (‘Clustered Regularly Inter-Spaced
Palindromic Repeats’) is a tool used for gene editing. The technique involves a
DNA cutting enzyme and a small tag which tells the enzyme where to cut. Cas9
stands for CRISPR-associated protein 9, and is the nuclease part that cuts the
