Genetics Review

2. a form of dominance wherein the alleles of a gene pair in a heterozygote are fully expressed. This results in offspring with a phenotype that is neither dominant nor recessive.
6. genotype having two different alleles
9. crossing over occurs in this stage of cell division
10. an epigenetic DNA modification
13. enzyme that made Henrietta Lacks famous
14. a molecule that adds a phosphate to another molecule
17. molecular technique using fluorescent probes that bind to only those parts of the chromosome with a high degree of sequence complementarity.
19. cancer-promoting form of a proto-oncogene
20. a circular piece of extrachromosomal DNA
21. prostate cancer histological test named after Donald ________.

3. sugar used in chain-terminating nucleotide triphophates
4. the opposite of a kinase
5. Two needed in PCR (singular form)
7. DNA sequences that define where transcription of a gene by RNA polymerase begins.
8. separates DNA strands like a "zipper"
11. a type of mutation that introduces a stop codon in place of a codon coding for an amino acid
12. one researcher who used Nitrogen isotopes in his experiments.
13. having three copies of genetic information
