The Impact of Human Genome Project on CRISPR-Cas9 Technologies

Introduction

The Human Genome Project (HGP) has revolutionized our understanding of human genetics and laid the groundwork for subsequent scientific advancements, such as gene-editing technologies like CRISPR-Cas9. Although CRISPR-Cas9 was developed after the HGP, it owes much of its foundational knowledge to the insights gained from this monumental project. By mapping the human DNA sequence, the HGP has provided critical resources for understanding gene functions, variations, and the mechanisms of genetic diseases, enabling the development of more precise and effective gene-editing technologies.

Key Concepts
