CSET Genetics And Evolution

Subjects : cset, science, genetics
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Is a base found in DNA and RNA. Cytosine pairs with Guanine in DNA






2. Hybrid is sterile so biologically unfit






3. The capacity of an individual of certain genotype to reproduce. It is usually equal to the proportion of the individual's genes in all the genes of the next generation






4. Describes the existence of a prezygotic reproductive barrier between two species as a result of them occupying or breeding in different habitats within the same general geographical area






5. Cross where you cross unknown genotype with a recessive






6. Genes contain instructions for assembling






7. Identical alleles for a gene






8. Building block of a protein






9. Translation occurs in the...






10. Speciation preceded by a period of geographical isolation






11. Condition in which an organism has extra sets of chromosomes






12. Name for oism with one dominant and one recessive allele






13. Any preserved remains of an organism from the past. Usually found in sedimentary rock.






14. Used x ray cyrstallography to create an image of DNA






15. Selection acting against the middle of a range of variation






16. When competition causes two closely related species to become more different in regions where their ranges overlap






17. Term used to refer to an organism that has two identical alleles for a particular trait. e.g TT is the homozygous genotype for Tall.






18. The number of times an allele appears in a population






19. Transcrition occurs in the...






20. The evolutionary history/geneology of a group of organisms (a tree thingy)






21. Any indirect evidence of life preserved as an impression in rock; trails - footprints - tracks - burrows - and bite marks






22. Describes the isolation of a physical barrier e.g. body of water (ocean) or mountains






23. Movement of organisms ro of from a population






24. One of the identical rods of a chromosome.






25. Ribosomal RNA; type of RNA that makes up part of the ribosome






26. A combining of genes or characters different from what they were in the parents






27. Heteros have a phenotype tintertmediate b/t phenotypes of the 2 homoz






28. DNA that is coiled around proteins






29. Science dealing with DNA and protein synthesis of living organisms. Manipulation of DNA.






30. Describes a cell - nucleus - or organism that has only one set of unpaired chromosomes






31. Three dimensional shape of organism made from a mold. May be created with plaster or over time with minerals.






32. Form of reproductive isolation in which structural differences in the anatomy of reproductive organs prevent sperm transfer between individuals of different species






33. Determined the complete double helical structure of DNA






34. Situation in which allele frequencies remain constant






35. What happens during the process of translation






36. Chromosomes are collections of many






37. The banding pattern of a persons DNA after being cut and run on gel is called






38. Innate trait; shared ancestry






39. Change to a chromosome in which part of the chromosome is repeated






40. Evolution of the earth - which is hypothesized to have been formed over 4.6 billion years ago.






41. A distinct population of a species that varies from other populations of the same species.






42. Embryos of similar organisms have very similar early development indicating similar DNA at work






43. Found only in that country






44. The specific location of a gene on a chromosome






45. A type of protein molecule found in the chromosomes of eukaryotic cells but not prokaryotic cells






46. A population partially isolated from other populations of the same species






47. The enzyme that binds to the promoter region of a gene during transcription is called...






48. Layers of compressed sedimentary rock demonstrate the order or sequence at which events occurred. Cannot delineate the exact point of time - but is able to distinguish the order of events.






49. An equilibrium in the occurence of two or more different froms within the same population usually caused by different allele combiinations of a gene






50. Method of replication that implies that each new strand of DNA is half original and half new
