Mutation = change in DNA message that can be copied into daughter cells, unless repair fixes it.
1. What is a chromosomal translocation?
2. Which point mutation type changes one base into another base?
3. What chromosomal mutation occurs when a chromosome region is reversed?
Mutations — definition?
Changes in DNA passed to daughter cells.
Genetic diversity — source?
Mutations create inherited variation.
DNA repair — role?
Corrects mutations, preventing transmission.
Protein synthesis — stages?
Transcription in nucleus, translation in cytoplasm.
Genetic code — function?
Links DNA codons to amino acids.
Transcription — mechanism?
Produces mRNA from DNA template.
