Chromosomal Mutation
Across
4. change in the amino acid that is coded for
7. some areas are more susceptible to mutations
14. a gene grows with each generation leading to a
worsened condition at a younger age
16. changes an amino acid into a stop codon
17. adds genetic material
18. is a change in the nucleotide sequence that composes a
gene.
19. intentional alteration of genes
21. mutation all cells that descend from original cell have
the same mutation
22. Mutation usually originates as an error in DNA
replication
Down
1. alter synthesis of proteins one amino acid at a time
2. “jumping genes”
3. not a coding gene but resembles a coding gene
5. mutation all cells that descend from gamete have the same mutation
6. chemical or radiation to induce mutation
8. two copies of a gene next to each other
9. a change in a single DNA base
10. unusual allele
11. removes genetic material
12. proofread DNA for misalignment of short repeated segments
13. most common allele in population
15. pieces are cut and errors are repaired
20. adding or deleting a number of bases that is not a multiple of 3
