Question options: ... a change to the RNA sequence of an individual a method to keep all individuals of a species the same a permanent change in the DNA sequence a mistake in the DNA sequence that can be fixed Hide Feedback Great job. Question 2 What direction do the two strands of DNA run? Question options: anti-parallel perpendicular transversal parallel Hide Feedback Great job. Question 3 What is the most common method for repairing nucleotide errors in DNA? Question options: nucleotide excision repair mismatch repair uracil base replacement thymine dimers Hide Feedback Great job. Question 4 What are the three components needed for protein synthesis? Question options: DNA, lysosome, exon mRNA, DNA, ribosome mRNA, tRNA, ribosome DNA, nucleus, ribosome Hide Feedback Great job. Question 5 How is it possible that each daughter cell during cell replication receives an identical copy of the DNA? Question options: DNA is not identical in every cell, so all daughter cells have different copies DNA is replicated individually in each new cell after meiosis and mitosis DNA is replicated during the synthesis phase of the cell cycle, prior to mitosis or meiosis DNA is replicated following mitosis or meiosis, so is transferred after the new cells are formed Hide Feedback Great job. Question 6 Which statement best describes prokaryotic chromosomes? Question options: Double-stranded, circular Double-stranded, linear Single-stranded, circular Single-stranded, linear Hide Feedback Great job. Question 7 A nucleotide includes all of the following parts EXCEPT? Question options: deoxyribose carbon dioxide nitrogenous base phosphate group Hide Feedback Great job. Question 8 Which nitrogenous base is present in RNA and not DNA? Question options: adenine cytosine uracil guanine thymine Hide Feedback Great job. Question 9 Why does one strand of DNA replicate as a continuous strand, and the other in fragments? Question options: they are parallel, and DNA polymerase can synthesize from 5' to 3' they are parallel, and DNA polymerase can synthesize in either direction they are anti-parallel, and DNA polymerase can only synthesize from 5' to 3' they are anti-parallel, and DNA polymerase can synthesize in either direction Hide Feedback Great job. Question 10 What is an example of a genetically modified organism? Question options: a plant produced through traditional breeding a natural cross between zucchini and acorn squash mating of a horse and donkey to produce a mule a red apple with a gene from another apple cultivar Hide Feedback Great job. Question 11 What is an example of a transgenic organism? Question options: a tomato with a gene for freezing tolerance from fish mating of a horse and a donkey to produce a mule an heirloom tomato variety a traditional breeding project where red and green apples are crossed Hide Feedback Transgenic is the result of foreign DNA that is a different species being transferred by recombinant DNA. Review cloning and genetic engineering in Chapter 10. Question 12 Gel electrophoresis separates charged molecules on the basis of what? Question options: size and charge temperature and shape contents and charge shape and color Hide Feedback Great job. Question 13 The introduction of a non-mutated gene at a random location to cure a disease by replacing a protein is called what? Question options: transgenic organism gene therapy reverse genetics recombinant DNA Hide Feedback Great job. Question 14 What is a basic definition of cloning? Question options: increasing the life expectancy of animals increasing the number of plants creation of a similar copy creation of a perfect replica Hide Feedback Great job. Question 15 Why was Dolly a Finn-Dorset and not a Scottish Blackface? Question options: enucleation occurred with a Scottish Blackface egg the surrogate ewe was a Finn-Dorset the nucleus came from a Finn-Dorset the cytoplasmic donor was from a Scottish Blackface Hide Feedback Great job. Question 16 What do the different bands in the same lane of an agarose gel represent? Question options: similar genetic make up links of protein different organisms different size pieces Hide Feedback Great job. Question 17 What is a plasmid with foreign DNA inserted referred to as? Question options: recombinant DNA restriction DNA foreign DNA host DNA Hide Feedback Great job. Question 18 Why are plants more difficult to make into transgenic species? Question options: presence of cell wall, preventing bacteria mammals are regulated, plants are not they are easier because they don't move the presence of chloroplasts, so photosynthesis is running Hide Feedback Great job. Question 19 Which is a good definition of genetic engineering? Question options: A process to determine the genetic makeup of an individual at a particular location in an individual's DNA an organism that has another species' DNA inserted into its genome using genetic techniques techniques of molecular biology that involves manipulation of genes DNA that contains genes from more than one source Hide Feedback Genetic engineering is a broad term that simply involves manipulation; it is used for other techniques. Review Biotechnology in the Weekly Lecture Lesson. Question 20 Asexual reproduction where the circular chromosome replicates and then the cell membrane and cell wall partition the chromosomes into two new cells is know as what? Question options: Animal reproduction Binary fission Viral integration Plant pollination Hide Feedback Great job. Question 21 Which type of stem cell can only become one specialized type of stem cell, depending on the origin? Question options: somatic embryonic reproductive induced pluripotent Hide Feedback Great job! Question 22 In data measurement, what does precision refer to? Question options: Whether or not a measurement was performed correctly. The number of significant digits in the solution of a mathematical problem How close a measured value is from a standard or established value How close a measured value is to previous measured values Hide Feedback Question 23 A digital thermometer is calibrated to be accurate within +/- 0.1 ˚C. Two temperature measurements are then taken that show the temperature is 24.9 ˚C and 25.1 ˚C? Do these measurements agree? Question options: Not enough information is given No Yes Hide Feedback Question 24 What are quantitative data measurements? Question options: Measurements that are appropriate for any type of variable Measurements of numerical variables and are displayed as numerical values Measurements that are appropriate in all experiments Measurements of categorical variables and can be displayed as types or descriptions Hide Feedback Quantitative data measurements are numerical variables – they provide data that answers questions like "how many" or "how often".
