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. Molecules that join together to form DNA and RNA. Monomers that make up a nucleic acid






2. A group of organisms of the same species occupying a given area.






3. Because of base pairing in DNA the amount of






4. Independent segregation of genes during the formation of gametes






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






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






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






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






9. 2 alleles for a character separate during the formation of gametes - so that each gamete only carriers one allele for each character

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






11. Trait evolves overtime; NO common ancestry






12. What does DNA stand for...






13. 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






14. Geologic period that followed the Precambrian;means 'ancient life' - early life (570-286 million years ago); single cell organisms - shells - mollusks - rise of first vertebrates - rise of land plants - amphibians - insects - seed plants - and trees






15. The preserved remains or traces of an organism that lived in the past






16. Disappearance of a species from all parts of its geographical range






17. What happens during the process of translation






18. Structures in different but related species that are derived from the same ancestral structure but now serve different purposes.






19. Dna moves during electrophoresis because of...






20. Evolution of superficial phenotypic similarity of form as a result of similar selection pressures






21. 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.






22. Populations that can interbreed with neighboring populations but not with populations separated by larger geographical distances






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






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






25. The independant evolution of similar traits - starting from a similar ancestral condition






26. Different alleles for a gene






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






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






29. Shows how the embryos of different groups resemble each other at particular stages. Similarities indicate groups may share a common ancestor






30. Breeding organisms with specific traits in order to produce offspring with identical traits






31. Building block of a protein






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






33. 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.






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






35. The final product of transcription is...






36. The backbone of DNA consist of...






37. Recognize and cut DNA at specific sequences usually palindromes






38. DNA that is coiled around proteins






39. Large - scale evolutionary changes that take place over long periods of time






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






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






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






43. When zygote does not complete development or is physically weaker than normal






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






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






46. Group of individuals of the same species that live in the same area






47. Consists of all genes - including all the different alleles - that are present in a population






48. Natural selection that causes the frequency of a particular allele to move in one direction






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






50. A DNA strand that has the bases CTAATGT forms a complete complementary double helix with
