Mutation & Protein Synthesis

Front

What is the structure shown in the middle of the pink box?

Back

Anticodon

Front

Which of the following statement is NOT true? Point mutation affects every codon beyond the point of mutation.

Back

This statement is NOT true; point mutations typically affect only the codon where the mutation occurs.

Front

Genetic info flows in one direction. Which best represents this flow?

Back

DNA-RNA-protein

Front

What is an example of a point mutation?

Back

Substitution of a single nucleotide.

Front

What is the term for a three-nucleotide sequence that codes for an amino acid?

Back

Codon

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to changes in protein synthesis.

Front

What is a frameshift mutation?

Back

A frameshift mutation occurs when there is an addition or removal of a base, altering the reading frame.

Front

What is a nonsense mutation?

Back

A nonsense mutation is a change in the DNA that creates a stop codon, terminating translation early.

Front

What is the role of tRNA in protein synthesis?

Back

tRNA transports amino acids to the ribosome, matching them to the codons in the mRNA.

Front

What is the difference between a point mutation and a frameshift mutation?

Back

A point mutation involves a change in a single base pair, while a frameshift mutation involves the addition or removal of bases.
