Both thymine and uracil are pyrimidine bases, but there’s a crucial difference: thymine has a methyl group that uracil lacks. This methylation process plays an essential role in protecting the DNA and ensuring the accuracy of genetic information. We’ll explore: The process of thymine formation from uracil through methylation The role of the enzyme DNA methyltransferase How thymine in DNA prevents mutations Why uracil is used in RNA for less stability How methylation protects DNA from nucleases and UV damage The impact of cytosine deamination and why uracil shouldn't be in DNA Watch to learn why thymine’s stability in DNA and uracil’s instability in RNA are crucial for cellular function and genome protection!
