Advances in Genetics
Across
- 2. These can be inserted into the cells of cows so that the cows produce the human protein needed in their milk.
- 3. An organism that has exactly the same genes as the organisms from which it was produced.
- 7. Selective breeding, cloning, and genetic engineering are three methods for developing organisms with these.
- 8. Genetic engineering can produce this and improve food crops.
- 10. This type of apple is a cross between McIntosh and Red Delicious.
- 13. In Mexico every year farmers saved these from the healthiest plants that produced the best food. This is an example of selective breeding.
- 16. Inserted genes in plant cells has helped them to survive in this.
- 17. All the DNA in one cell of an organism.
- 18. Breeders cross two genetically different individuals so the offspring has the best traits from both parents.
- 19. A genetically engineered bacteria produces this to help people with diabetes.
- 20. The crossing of two individuals that have similar characteristics.
Down
- 1. The main goal of this is to identify the DNA sequence of every gene in the human genome.
- 4. The process of selecting organisms with desired traits to be parents of the next generation.
- 5. Scientists have learned that the DNA of humans has at least 30,000 genes and the average gene has about 3000 of these.
- 6. Some bacteria cells contain small circular pieces of DNA called this.
- 9. Cloning an organism requires this to be take out of an animal's body cell.
- 11. Genes from one organism are transferred into the DNA of another organism.
- 12. These are used to create what is called a DNA fingerprint.
- 14. Inbred organisms have similar genetic characteristics that increase the probability of inheriting this.
- 15. This will involve inserting copies of a gene directly into a person's cells to correct genetic disorders.
- 18. Genetic engineering has allowed scientists to produce a blood clotting agent that people with this disorder need.
