New Cpf1 Molecular Scissors to Take Genomic Editing to the Next Level

CRISPR (Clustered Regularly Interspaced Palindromic Repeats) gene editing technology allows permanent modification of genes within organisms. It is considered a breakthrough in biotechnology ever since its discovery.  Researchers from the University of Copenhagen (Denmark), led by Spanish researcher Guillermo Montoya, now went one step further. They discovered how Cpf1, a new type of molecular scissors, unzip and cleave DNA.

Where Do Blue Eyes Come From?

Humans have many phenotypic variations in eye color which is determined by multiple genes. So far, up to 16 genes have been associated with eye color inheritance. However, scientists from the Institute of Forensic Genetics at the University of Copenhagen discovered that the reason for blue eyes mainly lies in two genes: OCA2 and HERC2. This way they have shown that the earlier belief that blue eye color is a simple recessive trait is incorrect.
