What is the function of the start codon AUG in protein synthesis?
What is the function of the start codon AUG in protein synthesis?
- It indicates a frameshift mutation
- It marks the end of the polypeptide chain
- It codes for the amino acid threonine
- It signals the beginning of the protein sequence (correct)
Which type of mutation changes a single nucleotide in the DNA template, potentially leading to the production of an abnormal protein?
Which type of mutation changes a single nucleotide in the DNA template, potentially leading to the production of an abnormal protein?
- Point mutation (correct)
- Silent mutation
- Frameshift mutation
- Nonsense mutation
What is the effect of a silent mutation on the resulting protein?
What is the effect of a silent mutation on the resulting protein?
- It changes the amino acid sequence of the protein
- It has no effect on the amino acid produced by the codon (correct)
- It leads to the production of a non-functional protein
- It causes a frameshift in the reading frame
