question 77

Multiple Choice

The Human Genome Project is a multinational project that reported complete identification of more than 20,000 genes in human DNA. Growing understanding has associated "normal" and naturally variable versions of the genes, producing specific proteins for human health and cell functions. Numerous mutated versions of the genes have been associated with particular human health problems and disease, due to the types of cells where mutations occur, the specific genes affected, and the type and extent of mutation. In these cases, the structure and function of proteins is ultimately impacted. Examine these examples to apply your knowledge of mutations to the descriptions provided.
-In a "silent" mutation the

• A) codon that mutates causes a change in the amino acid specified.
• B) codon that mutates does not cause a change in the amino acid specified.
• C) mutation does not occur in a codon.
• D) codon that mutates causes a stop codon to occur instead of the placement of an amino acid.
• E) mutation is not in DNA.
