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. In DNA its partner is Thymine. In RNA its partner is Uracil






2. Term used to refer to an organism that has two different alleles for the same trait. e.g Tt is the heterozygous genotype for Tall.






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






4. Trait evolves overtime; NO common ancestry






5. T or F a codon consist of three nucleotides






6. Any agent that can cause a change in DNA






7. The region of the chromosome that holds the two sister chromatids together during mitosis






8. Innate trait; shared ancestry






9. A pairing where the parent plants differ in only one character.






10. The signal on a mRNA molecule that designates the end of the coding sequence is called the...






11. Evolutionary process in which a species or related species folllow different evolutionary paths to eventually become less related






12. 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.






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






14. Earth's history organized into four eras: Precambrian - Paleozoic - Mesozoic - and Cenozoic






15. A type of barrier between species; the species remain isolated because male and femal gametes of the different species cannot fuse - or they die before they unite.






16. Process by which an organism is slowly turned to stone as the body is replaced by minerals.






17. Different alleles for a gene






18. Selection against one end of a range of variation - resulting in a progressive change in allele frequency






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






20. The gradual changes in gene frequencies in a population due to random events






21. Organism is preserved at very low temperatures. Preservation of both hard and soft parts can occur.






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






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






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






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






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






27. A change in the base sequence of a gene






28. One of the types of fossils made from hardened tree resin. Preserves both hard and soft parts.






29. The movement of individuals into an area






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






31. What happens during the process of translation






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






33. Separates DNA by size






34. Selection acting against the extremes of a range of variation - resulting in resistance to change in allele frequencies






35. All the genes in a population. genes are added by reproduction and immigration and lost by death and emigration






36. A model for the evolution of different froms over a long period of time but with only slight chchanges occring between successive generations






37. A taxon originating from and including a single common ancestor






38. Era of recent life that began about 66 million years ago and continues today; includes the first appearance Hominids






39. Is the genetic makeup of an organism (TT or Tt) ; All the combinations of genes you have for a certain trait.






40. Proteins are made of...






41. Type of rock made from small pieces of other rocks and organisms pressed together. Source of fossil preservation. Limited radioactive or absolute dating potential.






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






43. A copy of a gene is made during a process called this






44. Process in which DNA is duplicated






45. Organisms with similar functions - but different underlying structure. Example: bird and insect wing. These structures do NOT show a common ancestral link.






46. A change or error in the DNA sequence






47. Features that are superficially similar but have different modes of development






48. All the factors in an organism's surroundings that can potentially affect it






49. Form of reproductive isolation in which two populations reproduce at different times






50. Inherited feature that tends to prevent species from interbreeding with other species
