Exploring DNA Analysis Methods and Genetic Research Applications in Low and Middle-Income Nations: A Study of Sri Lanka

Abstract

Using Sri Lanka as a case study, the paper explores how DNA analysis has transformed genetic research, particularly in low and middle-income countries (LMICs). It discusses various DNA analyzing techniques, from traditional methods like Sanger sequencing to advanced techniques such as next-generation sequencing (NGS) and CRISPR-Cas9, highlighting their applications in disease research, population genetics, and forensic science. Sri Lanka's advancements in genetic research, including DNA sequencing, typing, and recent developments in X-chromosome-based DNA typing, are emphasized. The paper also examines challenges and opportunities in LMICs regarding genetic research and underscores the importance of DNA analysis in advancing personalized medicine and understanding genetic diversity. Additionally, it discusses Sri Lanka's efforts in education and training in molecular biology. It explores the country's rich genetic diversity and demographic history, focusing on ethnic studies and historical interactions among different population groups. Overall, the paper highlights the significance of DNA analysis in genetic research and its potential implications for LMICs. Sri Lanka is a notable example of progress in the field.
