BioBeyond Unit 6: Genetic Blueprints Questions and Answers Graded A

BioBeyond Unit 6: Genetic Blueprints Questions and Answers Graded A What did the genetic material have to do, according to Mendel? Select all that apply: Be passed on unchanged from parent to child Be a trait passed on to the next generation even though it may be hidden in an individual Be present in each organism in two copies, one from each parent Experiment 1: Non-infectious bacteria Which kind of bacteria was injected? Non-infectious bacteria Experiment 2: Infectious bacteria Which kind of bacteria was injected? Infectious bacteria Experiment 3: Heat-killed infectious bacteria Which kind of bacteria was injected? Heat-killed infectious bacteria Drag either the dead or the live mouse over the question mark, then hit next to find out the actual results of the experiment Mouse dies Which do you think is the best explanation for why the mouse died in the fourth experiment? The dead infectious bacteria passed information to the non-infectious bacteria, allowing it to become infectious Step 2 picture that the two bubbles are connected Step 3 two separate circles What conclusions can you draw from the finished sequence that occurred with the bacteria to the right? Select all that apply: Bacteria can pass on non-living material that results in changes in other bacteria One bacterium incorporated new genetic material into its own Some bacteria can share genetic material with other bacteria True or False: Humans also do this horizontal infomation passing or transfer and are able to pass on and pick up information from other humans and other organisms. False Which ones are biological macromolecules? Select all that you think apply: Proteins Nucleic Acid Lipids Carbohydrates Which of these macro-molecules do you think is the genetic material - the blueprint for our personal traits, passed from parents to child? protein If your hypothesis (nucleic acids are the genetic material) is accurate, what results would you expect? Select all that apply: proteins will be transferred from the virus to the bacteria The bacteria will be changed after the infection Choose a molecule to label, like in the Hershey-Chase experiment, where the molecule was labeled radioactively in a virus, called a bacteriophage (right), that infects bacteria and causes them to incorporate its genetic material Will chose all to run an experiment on What is one interpretation of these results? Lipids are not the genetic material What is one interpretation of these results? Proteins are not the genetic material What is one interpretation of these results? Nucleic acids are the genetic material What is one interpretation of these results? Carbohydrates are not the genetic material What conclusion do your results support? Nucleic acids are the genetic material Do your results support your hypothesis (nucleic acids)? My results do not support the hypothesis Do your results support the early 20th century hypothesis that proteins are the genetic material? My results do not support the hypothesis Build Nucleotides Drag the ingredients from the left, and drop them in boxes below. Each nucleotide has a similar structure. It has a base, a sugar, and a phosphate. Build Single- Stranded DNA Drag the nucleotides from the box on the left. What parts of the nucleotides you built connect to each other to form the chain? Select all that apply: Phosphate Sugar What repeating unit forms the chain connecting the nucleotides? Select only the best answer: Phosphate-Sugar Which details became clear about DNA from Photo 51? Select all that apply: The sugar-phosphate backbone is on the outside The radius of DNA is 1 nanometer What was Rosalind Franklin's contribution to the discovery of the structure of DNA? Select the best answer: Wilkins showed Franklin's data to Waston Crick without her knowledge allowing them to... What were the key new features of Watson and Crick's model? Select all that apply: Specific base pairing Bases on the inside Build Double- Stranded DNA Drag the nucleotides from the box on the left. Which nucleotides bond with each other to give the DNA molecule the correct radius? Select all that apply: A and T C and G Which part of the nucleotides you built connects the two strands? Select only the best option: Base Choose the letter of the correct schematic. Top to bottom S A P What color is the backbone? Orange What color are the bases? Purple What differences do you see? Select all that apply: The sugar is different What differences do you see? Select all that apply: The sugar is different
