Help with my Biology Homework

I'm new to biology and i'm a little nervous with my answers. Can you guys give this a try so I can compare them with mine? Thanks!


1. The production of sex cells by two divisions resulting in four daughter cells that contain half the original number of chromosomes
2. A double-stranded molecule that contains the genetic code
3. Reproductive cells developed from cells in ovaries and testes
4. Structures contained within the cytoplasm of eukaryotic cells that convert energy, derived from nutrients
5. Simple cell division; the process by which somatic cells divide to produce two identical daughter cells
6. The portion of the DNA that is responsible for making a complete protein or some other function
7. The building blocks of proteins
8. The exchange of genetic material between partner chromosomes during meiosis
9. Triplets of messenger RNA bases that code for specific amino acids during protein synthesis
10. Structures composed of DNA and protein found only in the nuclei of cells
11. A cell formed by the union of an egg cell and a sperm cell
12. Three-dimensional molecules that serve a wide variety of functions through their ability to bind to other molecules
13. The type of RNA that binds to amino acids and transports them to the ribosome during protein synthesis
14. A form of RNA that is assembled on a sequence of DNA bases that carries the DNA code to the ribosome during protein synthesis
15. All the cells in the body except gametes (sperm and eggs)
