What are pathogenic repeats?
Pathogenic repeats are sequences of DNA that can cause genetic disorders due to their instability and tendency to expand during replication.
How does 2-dimensional gel electrophoresis work?
2-dimensional gel electrophoresis separates DNA fragments based on size and charge, allowing for detailed analysis of replication dynamics.
Why is replication fork stalling significant?
Replication fork stalling can lead to genomic instability, which is a hallmark of many diseases, including cancer.
What is the goal of this research?
The goal is to understand how specific DNA repeats affect replication processes and contribute to genetic disorders.
What implications do the findings have?
The findings may inform future therapeutic approaches for diseases associated with DNA replication errors.
