UPSC Syllabus Topic: GS Paper 3-Science and Technology- developments and their applications and effects in everyday life
News: The article discusses AlphaFold 3, a tool developed by Google’s DeepMind that predicts protein structures. It highlights the tool’s advancements and its ability to model other molecules but notes limitations to it. Significance of AlphaFold 3
What is AlphaFold?
AlphaFold: An AI tool developed by Google’s DeepMind in 2018 to predict how proteins fold.
Purpose: It aims to identify the 3D shapes of proteins based on their amino acid sequences, which is crucial for understanding biological functions and disease mechanisms.
Development History: The initial release in 2018 came five decades after the protein-folding problem was identified. It has been followed by improved versions, including AlphaFold 2 and the latest, AlphaFold 3, which also models DNA, RNA, and other molecules.
Accuracy: AlphaFold 3 has nearly 80% accuracy in predicting protein structures, showcasing significant advancements in the field.
Why is protein folding important?
Biological Function: Proteins need to fold into specific shapes to perform their biological functions properly.
Health Implications: Misfolded proteins can cause diseases, making understanding protein folding crucial for medical research.
Drug Development: Knowledge of protein structures aids in the development of drugs by providing insights into how they interact with the body.
What are the limitations of AlphaFold 3?
Explanatory Limits: AlphaFold 3 can predict how proteins fold but does not explain why they fold in that specific way, a task remaining for human scientists.
Drug Discovery Impact: Technology’s role in accelerating drug development is uncertain. It doesn’t address all the interactions between drug components and the body, which are critical for clinical trial success.
Access and Transparency: The use of AlphaFold 3 is restricted, and its algorithms are not open for public scrutiny, which could hinder broader research and innovation.
