Across
- 3. An allele which is always expressed, even if only one is present. Dominant alleles are assigned uppercase letters.
- 5. A genetically determined characteristic.
- 10. An allele that is only expressed when both alleles are recessive in the organism. Recessive alleles are assigned lowercase letters.
- 11. Threadlike structure of nucleic acid and protein found in the nucleus of most living cells. They carrying genetic information in the form of genes.
- 12. Nucleotides from the basic structural until have DNA. Composed of a sugar, a phosphate, and a base.
- 14. Having the same structural features and pattern of genes.
- 15. The specific alleles that occur in an organism.
Down
- 1. The observable characteristics of an organism resulting from its genotype.
- 2. Large, biologically important polymers comprised of sequences animo acids.
- 4. Having two alleles have the different types for a particular trait.
- 6. Different forms of the same gene. They can be dominant or recessive.
- 7. Part of DNA that are involved in pairing. The bases on DNA are cytosine, guanine, adenine, and thymine.
- 8. The organelle within a cell that contains DNA.
- 9. A short length of DNA that carries the genetic code for a particular characteristic or cell activity.
- 13. Having two alleles of same types for a particular trait.
