Question

select three possible ways mutations can be acquired.
select the three answers that are correct.
□ being exposed to substances that damage dna
□ inheriting mutations from one’s parents
□ transcribing dna incorrectly during protein synthesis
□ leaving mistakes uncorrected during dna replication
□ receiving mutations through a vaccination

Explanation:

• Exposure to DNA - damaging substances: Mutagens like certain chemicals or radiation can alter DNA structure.
• Inheritance from parents: Mutations in germ - line cells (sperm and egg) can be passed to offspring.
• Uncorrected DNA replication errors: DNA polymerases can make mistakes during replication. If the proof - reading and repair mechanisms fail, these errors (mutations) remain.

• Transcribing DNA incorrectly during protein synthesis: This is part of normal gene expression variation and not a common way to acquire mutations.
• Receiving mutations through a vaccination: Vaccines are designed to be safe and do not cause mutations.

Answer:

• being exposed to substances that damage DNA
• inheriting mutations from one’s parents
• leaving mistakes uncorrected during DNA replication
