3. The composite of an organism's observable characteristics or traits, such as its morphology, development, biochemical or physiological properties, behavior, and products of behavior (such as a bird's nest).
4. Any cell of a living organism other than the reproductive cells.
6. A cell or nucleus which contains two copies of genetic material, or a complete set of chromosomes, paired with their homologs
8. A haploid cell that fuses with another haploid cell during fertilization (conception) in organisms that sexually reproduce.
10. The biological process of producing two identical replicas of DNA from one original DNA molecule.

1. The structure formed by double-strandedmolecules of nucleic acids such as DNA.
2. The process whereby biological cells generate new proteins; it is balanced by the loss of cellular proteins via degradation or export.
5. The building blocks of protein.
7. A molecule composed of two chains (made of nucleotides) which coil around each other to form a double helix carrying the geneticinstructions used in the growth, development, functioning and reproduction of all known living organismsand many viruses.
9. The study of genes, genetic variation, and heredity in living organisms.
11. A variant form of a given gene.
