3. RNA which is bound to the ribosome
5. allele expressing itself
7. process where proteins are built from the mRNA blueprint
10. portions of DNA molecules that determine characteristics of living things
12. gene composition of a living organism
13. how many copies of each gene every person has
14. cells in most complex organisms
16. first step towards making proteins
17. developed by biologists
18. study of how genes bring about characteristics or traits
19. expression of the genes of living things

1. recessive allele
2. situation in which both alleles are equally strong and both alleles are visible in the hybrid genotype
4. consists for about 100,000 genes for a human cell
6. different forms of gene
8. Mendel believed that certain factors are passed from parents to their ---------
9. model for the structure of DNA was proposed by them
11. science of genetics was developed by him
14. the true structure of a DNA molecule
15. cells formed through meiosis
