Genetics

1. A gene that can mutate to an allele, that causes a cell to become cancerous.
3. law: A law developed in 1908 that is the basis for calculations used in population genetics. The formula allows us to calculate the frequencies of genes, phenotypes, and genotypes when the frequency of a genetic trait is known.
7. Observable regions in which non-sister chromatids of homologous chromosomes cross-over each other.
8. A postulated unit of gene action that consists of an operator and the closely linked functional genes it controls.
9. The DNA base sequences interrupting the protein-coding sequences of a gene
10. Formation of double-stranded nucleic acid from single stranded forms.
11. An orderly diagram of a family's relevant genetic features, extending back to at least both sets of grandparents and preferably through as many generations as possible.

2. Small single-stranded segments of DNA typically 20-30 nucleotide bases in size which are synthesized in vitro.
4. the interaction of genes that are not alleles, in particular the suppression of the effect of one such gene by another
5. Genes are on the same chromosome but are not close enough for linkage to be demonstrated.
6. mutation A single DNA base change which leads to a codon specifying a different amino acid.
