- Uracil also belongs to the pyrimidine family, and it pairs with adenine in the same way that thymine does, using two hydrogen bonds. (nagwa.com)
- In DNA, however, uracil is readily produced by chemical degradation of cytosine, so having thymine as the normal base makes detection and repair of such incipient mutations more efficient. (pfeiffertheface.com)
- mostly due to the deamination of cytosine to uracil via hydrolysis-which releases ammonia. (pfeiffertheface.com)
- When thymine is used the cell can easily recognize that the uracil doesn't belong there and can repair it by substituting it by a cytosine again. (pfeiffertheface.com)
