- 2. is the mode of cell replication for the formation of sperm and egg cells in plants, animals, and many other multicellular life forms.
- 3. identical alleles at corresponding chromosomal loci
- 4. of a cell involved in energy production
- 6. both alleles are the same, the gene is said to be homozygous.
- 7. code for proteins that attach to the genome at the appropriate positions and switch on a series of reactions called gene expression.
- 8. all genetic information is found in nuclear DNA. Both plants and animals have an organelle-a "little organ" within the cell- called the mitochondrion.
- 9. division that produces reproductive cells
Down
- 1. of the information encoded in a gene first into messenger RNA and then to a protein
- 5. DNA
