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






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






3. Cell division in which the nucleus divides into nuclei containing the same number of chromosomes. Mitosis involves growth and repair and occurs in the body cells.






4. What is one benefit for having two strands of DNA?






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






6. A codon is made of...






7. What happens during the process of translation






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






9. Movement of alleles into or out of a population due to the migration of individuals to or from the population






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






11. Identical alleles for a gene






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






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






14. Transfer RNA; type of RNA that carries amino acids to the ribosome






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






16. 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.






17. The complete genetic material contained in an individual






18. During transcription an RNA molecule is formed






19. The movement of individuals into an area






20. Which type of Rna functions as a blue print of the genetic code






21. Gradual evolution within a lineage






22. The formation of new species as a result of evolution






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






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






25. Synonym for protein; chain of amino acids






26. Process in which DNA is duplicated






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






28. Even if the gametes of the two species meet - fertilization does not occur






29. Selection for the ability to obtain a mate






30. T or F A cloned organism has the same proteins as another organism






31. A change in the base sequence of a gene






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






33. Of a cell or organism having two sets of homologous chromosomes or twice the haploid number






34. The sum total of an organism's requirements; its way of life






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






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






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






38. Recognize and cut DNA at specific sequences usually palindromes






39. Copying the code from DNA onto mRNA






40. Cell division that produces reproductive cells or gamates.This occurs in the gonads (testicle and ovaries in animals) Here the chromosome number is halved the original amount. (each new cell has a haploid number = n) All daughter cells are not geneti






41. Evolution resulting from small specific genetic changes that can lead to a new subspecies






42. Is found in DNA






43. Mating of 2 oism that differ in 2 characters






44. Speciation which does not involve a period of geographical separation






45. Is a base found in DNA and RNA. In DNA its partner is Thymine. In RNA its partner is Uracil






46. T or F a codon consist of three nucleotides






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






48. What does DNA stand for...






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






50. A DNA double helix is held together in the center by between nitrogenous bases
