| Question | Answer |
| Branch of biology that deals with heredity, variation and the expression of inherited traits | Genetics |
| All organisms use _ as genetic material. | DNA |
| Process of converting DNA to mRNA | Transcription |
| Process of converting mRNA to protein | Translation |
| Genes are expressed at the _ level. | Molecular |
| Proteins function at the _ level. | Cellular |
| Organism's traits determined by characteristics of _. | Cells |
| Chemical nature of genes, control and expression of genetic information; gene is focus | Molecular genetics |
| Passage of genes from parent to offspring, offspring traits; individual is focus | Transmission genetics |
| Genetic composition of populations and how it changes over time and geographic location; population's gene pool (frequency of genes in population) is focus | Population genetics |
| Unit of heredity; a segment of DNA that produces a functional product (usually a polypeptide) | Gene |
| Unique structure stores information that codes for proteins that have some function in the cell | DNA (Deoxyribonucleic acid) |
| Four criteria that must be met for genetic material | Information (contain information necessary to build an entire organism); Transmission (must be passed from parents to offspring during reproduction); Replication (must be copied); Variation (must vary in ways that can account for the known (phenotypic) differences within species) |
| In 1928, Griffith experimented with Streptococcus pneumoniae, which identified a __. | Transformation principle |
| Describe Griffith's experiments | Two strains of Strep. experimented with mice blood streaks, tells which kill mice and which don't; figure out that genetic material being "picked up"; transformation principle |
| In the 1940s, Avery, MacLeod, and McCarty's biochemically purified bacterial extracts, which helped figure out that the "transforming principle" was _. | DNA |
| Describe the "Transforming principle" isolation experiment | DNA extract divided into 3: one treated with DNAse, RNase, and Protease |
| In 1952, Hershey and Chase's experiments with T2 bacteriophage, which supported that _. | DNA is the genetic material |
