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. Type of sympatric speciation that occurs when a new species is formed because of a change in microhabitats






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






3. The study of the past and present distribution of species.






4. To create a recombinant DNA molecule - one would have to first cut two DNAs with creating before pasting them together






5. Is a base found in DNA and RNA. This base pairs with Cytosine in DNA






6. Structure present in an organism however does NOT have a known function. May link organisms with similar vestigial structures. Example: appendix - coccyx bone - whale leg bones.






7. An organism that has characteristics resulting from chromosomal alteration. This is a result of crossing over of the chromosomes during Meiosis - mutations and random segregation.






8. Because of base pairing in DNA the amount of






9. Building block of a protein






10. Any agent that can cause a change in DNA






11. Translation occurs in the...






12. A codon is made of...






13. A mutation in which one nucleotide is replaced by another nucleotide






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






15. The evolutionary process by which a species becomes better suited to its niche.






16. T or F a codon consist of three nucleotides






17. Group of similar organisms that can breed and produce fertile offspring






18. Natural disaster eliminates most of the population - members left contribute the alleles for the new population.






19. The molecules responsible for bringing amino acids to the ribosome during protein synthesis are






20. Found only in that country






21. Reciprocal evolution in two species as a result of the selection pressure each imposes upon the other






22. A change in the base sequence of a gene






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






24. Determined the concept of complementary base pairing






25. Independent segregation of genes during the formation of gametes






26. The adaptive increase in pigmentation as a result of human - induced pollutants






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






28. Ribosomes are made of...






29. How often a form of a gene appears in a gene pool






30. The condition in which there is no change in allele frequencies from generation to generation (i.e. no evolution)






31. The study relating the evolution of new charateristics to changes in the genes controlling development






32. An ancestor that two or more descendants have in common






33. Actual remains of an organism such as bones - teeth - shells - etc.






34. Mating of an individual of unknown genotype but dominant phenotype w/ a homozygous recessive individual






35. When F1 is fully fertile but F2 has low fertility (rice - cotton)






36. Which structure contains anticodons






37. Physical characteristics of an organism based on its genotype. e.g. Plant that has a genotype of TT will have a phenotype of Tall.






38. Speciation preceded by a period of geographical isolation






39. Relatively rapid proliferation from an ancestral type into new types which fill a diversity of ecological niches






40. A trait that masks the expression of another trait






41. A base found in DNA (but not in RNA). This base pairs with Adenine.






42. Messenger RNA; type of RNA that carries instructions from DNA in the nucleus to the ribosome






43. Trait evolves overtime; NO common ancestry






44. Change in allele frequencies as a result of the migration of a small subgroup of a population






45. A process that results in an allele having a different probability of remaining in the gene pool compared with that of another allele






46. The movement of individuals into an area






47. Human - like species that existed millions of years ago as witnessed through fossil evidence.






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






49. A point of overlap of paired chromatids at which fusion and exchange of genetic material (crossing over) occurs during prophase I of meiosis.






50. Organisms with a similar underlying structure - but different function. Example: bird - bat and dolphin 'arm'. Shows a common ancestral link.
