Questions & Answers

Q: What are tautomeric shifts?

Tautomeric shifts are a type of structural isomerism where molecules can interconvert between two different forms due to changes in connectivity or functional groups.

Q: How do tautomeric shifts affect nucleobases?

Tautomeric shifts can cause changes in the structure of nucleobases, leading to atypical base pairings during DNA replication, which can result in mutations.

Q: What is an example of a tautomeric shift in nucleobases?

Adenine and cytosine can undergo a tautomeric shift, switching between an amino form and an imino form. Similarly, guanine and thymine can shift between a keto form and an enol form.

Q: How do tautomeric shifts impact protein synthesis?

Tautomeric shifts can introduce mutations in the DNA sequence, leading to changes in the corresponding amino acids during protein synthesis.

Summary & Key Takeaways

  • Tautomeric shifts are a type of structural isomerism where molecules interconvert between two different forms.

  • Adenine and cytosine can exist in an amino form and imino form, while guanine and thymine can exist in a keto form and enol form.

  • These tautomeric shifts can lead to changes in DNA replication, resulting in mutations and different amino acids during protein synthesis.
