Investigating Stop Codon Readthrough In Saccharomyces Cerevisiae, Amy Kwon
Investigating Stop Codon Readthrough In Saccharomyces Cerevisiae, Amy Kwon
Undergraduate Student Research Internships Conference
Stop codon readthrough occurs via genetic and epigenetic mechanisms, resulting in a longer polypeptide chain at the C-terminus. Although these readthroughs may seem like an error made by translational mechanisms, evidence from yeast suggests that stop codon readthrough has an impact on various cellular processes. Readthrough has the potential to create genetic diversity, similar to RNA splicing, mRNA editing, and protein modification. The diversity created by translational readthrough may result in a beneficial change in phenotype, and thus have a role in evolution and adaptability. Translational readthrough is observed in organisms such as yeast and E. coli but may also …
