Across
- 3. the process by which a sequence of nucleotide triplets in a messenger RNA molecule gives rise to a specific sequence of amino acids during synthesis of a polypeptide or protein.
- 6. differential survival and reproduction of individuals due to differences in phenotype
- 8. a change or the process of change by which an organism or species becomes better suited to its environment.
- 10. the process by which genetic information represented by a sequence of DNA nucleotides is copied into newly synthesized molecules of RNA, with the DNA serving as a template.
- 12. the genetic constitution of an individual organism.
- 13. a distinguishing quality or characteristic, typically one belonging to a person.
- 14. the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations, caused by the alteration of single base units in DNA, or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes.
- 15. a unit of heredity which is transferred from a parent to offspring and is held to determine some characteristic of the offspring.
Down
- 1. a thing that is inherited.
- 2. the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.
- 4. present on its own will not affect the individual. Two copies of need to be present for the phenotype to be expressed.
- 5. a self-replicating material that is present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information.
- 7. how well a species is able to reproduce in its environment
- 9. diagram that is used to predict the genotypes of a particular cross or breeding experiment
- 11. phenomenon of one variant of a gene on a chromosome masking or overriding the effect of a different variant of the same gene on the other copy of the chromosome
