In the context of the wobble hypothesis, what does the term 'wobble' refer to?

• Flexibility in the third base of a codon

• Instability of the DNA helix

• Random mutations in DNA

• Errors in DNA replication

How does the wobble hypothesis contribute to genetic coding?

• It allows a single tRNA to recognize multiple codons.

• It increases the mutation rate.

• It stabilizes the DNA structure.

• It prevents DNA replication errors.

What is the significance of the wobble position in tRNA?

• It allows for fewer tRNAs to cover all codons.

• It increases the number of tRNAs needed.

• It stabilizes the tRNA structure.

• It prevents tRNA degradation.

Which of the following is an example of a wobble base pair?

• G-U

• A-T

• C-C

• G-G

What role does the wobble hypothesis play in protein synthesis?

• It allows for efficient translation by reducing the number of tRNAs needed.

• It increases the speed of DNA replication.

• It enhances the accuracy of DNA transcription.

• It stabilizes the ribosome structure.

How does the wobble hypothesis affect the genetic code's redundancy?

• It increases redundancy by allowing multiple codons to code for the same amino acid.

• It decreases redundancy by limiting codon options.

• It has no effect on redundancy.

• It eliminates redundancy entirely.
