Across
- 3. similar anatomy in different types of animals
- 8. all living organisms are related to one another
- 10. loss of all of a part of a chromosome
- 13. each individual has a unique combination of inherited traits
- 14. making RNA from a sequence of DNA bases
- 16. the individuals with the best traits and adaptions will survive and have the opportunity to pass on it's traits to offspring
- 18. spliced back together to form the final mRNA
- 20. chemical or agent in he environment that cause mutation
- 22. organisms that are adapted to an environment survive and reproduce more than others
- 24. RNA comtains letters of a language called the
- 25. gene mutations that involve changes in one or a few nucleotides
- 26. the process of change over time
Down
- 1. long chains of amino acids
- 2. part of chromosome breaks off and attaches to another
- 4. a nucleus acidthat consists of a long chain of nucleotides
- 5. extra copy of all or part of a chromosome
- 6. cut out and discarded
- 7. untwists the double helix and exposes complementary strands
- 9. reverses direction of parts of a chromosome
- 11. reads along each naked single strand adding complementary nucleotide
- 12. puts down a short piece of rna termed the primer
- 15. each species produces more offspring that can survive
- 17. individuals compete for limited resources
- 19. decoding of mRNA into protein
- 21. splices together the short segments of the discontinuous strand
- 23. heritable changes in genetic information
