Across
- 6. how common an allele is in a population
- 10. artificially made DNA strand that is formed by the combination of two or more gene sequences
- 11. The condition where a gene pool is not changing in frequency across generations
- 15. a process that uses laboratory-based technologies to alter the DNA makeup of an organism
- 17. the change in frequency of an existing gene variant in the population due to random chance
- 18. complete set of DNA in an organism
- 20. the transfer of genetic material from one population to another
- 21. a substance, organism or agent capable of causing cancer
- 24. An abnormal mass of tissue that forms when cells grow and divide more than they should or do not die when they should
- 25. failure of the chromosomes to separate, which produces daughter cells with abnormal numbers of chromosomes
- 26. laboratory technique for determining the exact sequence of nucleotides, or bases, in a DNA molecule
- 28. the loss of genetic variation that occurs after outside forces destroy most of a population
Down
- 1. having three or more sets of chromosomes
- 2. the insertion or deletion of nucleotide bases in numbers that are not multiples of three
- 3. a disease caused when cells divide uncontrollablely and spread into surrounding tissues
- 4. an animal, plant, or microbe whose DNA has been altered using genetic engineering techniques
- 5. differences between organisms within the same species
- 7. an organism or cell whose genome has been altered by the introduction of one or more foreign DNA sequences from another species by artificial means
- 8. laboratory method used to make many copies of a specific piece of DNA from a sample that contains very tiny amounts of that DNA
- 9. protein isolated from bacteria that cleaves DNA sequences at sequence-specific sites, producing DNA fragments with a known sequence at each end
- 12. structures made from DNA sequences and proteins found at the ends of chromosomes
- 13. a circular piece of DNA distinct from chromosomal DNA; found in bacteria
- 14. the reduction in genomic variability that occurs when a small group of individuals becomes separated from a larger population
- 16. chemical or physical agent capable of inducing changes in DNA called mutations
- 19. the combination of all the alleles and genes present in a reproducing population or species
- 22. occurs in a genome when a single base pair is added, deleted or changed
- 23. a chemical test that shows the genetic makeup of a person or other living things
- 27. a technique that uses a gene to treat, prevent or cure a disease or medical disorder
