Across
- 2. DNA sequence variations; Responsible for genetic diversity
- 3. scattered throughout nucleus or near nuclear envelope; not actively being transcribed
- 4. drift variation in frequency of different genotypes in a small population due to chance disappearance of particular genes as individuals die or do not reproduce
- 5. code multiple codons specify the same amino acid, makes it more difficult for mutations to change the protein sequence
- 8. flow different populations mate and exchange genes; Over time the 2 populations become genetically similar
- 9. change in DNA sequence; Can cause disease
- 11. 3 nucleotide sequence that codes for a particular amino acid
- 12. chromosomes separate, cells divide
- 13. your genes
- 15. the process of formation of female gametes; begins inside the fetus before birth
- 16. frame set of codons that codes for a protein
Down
- 1. visual display of all chromosomes; helps check numbers and appearance of genetic compliment
- 2. the phase of mitosis in which chromosomes attach
- 6. RNA polymerase binds to promote region on DNA; the promoter directs which DNA strand will be transcribed
- 7. the phase of mitosis in which chomosomes relax
- 10. effect Population established by small group of an original population
- 14. type of translocation involves only chromosomes 13, 14, 15, 21 and 22, because the ends of their short arms have similar repetitive DNA sequences that predispose to their fusion
