- Q 1/6Score 0Researchers combined sequences of fruit-fly DNA from a gene for a particular trait with frog DNA. The mixture was heated to separate the DNA strands. Cooling allowed the single strands to form pairs. The researchers observed that some of the fruit-fly DNA paired with frog DNA. The results provide evidence that —29fruit flies and frogs can be made to develop some of the same physical traitsthe replication of genetic material can occur at any temperatureheat can cause mutations in the DNA sequences of organismssimilar nucleotides are present in both fruit-fly and frog DNA

- Q1Researchers combined sequences of fruit-fly DNA from a gene for a particular trait with frog DNA. The mixture was heated to separate the DNA strands. Cooling allowed the single strands to form pairs. The researchers observed that some of the fruit-fly DNA paired with frog DNA. The results provide evidence that —fruit flies and frogs can be made to develop some of the same physical traitsthe replication of genetic material can occur at any temperatureheat can cause mutations in the DNA sequences of organismssimilar nucleotides are present in both fruit-fly and frog DNA30sB.6.B: Genetic Code
- Q2In the early 1980s scientists were able to produce two biomolecules by splicing a human gene into the bacterium E. coli to make recombinant human insulin and growth hormone. Which statement best explains why this experiment was successful?Human cells are eukaryotic, and E. coli cells are prokaryoticThe genes for all organisms are composed of the same building blocksThe human body contains many types of bacteria, including E. coliAll living organisms share the same genome30sB.6.B: Genetic Code
- Q3Organisms can be classified based on homology, which is shared characteristics inherited from a common ancestor. In the past, homologies were based on studies of anatomical structures and patterns of embryonic development. In more recent years, the use of molecular biology techniques has allowed homologies to be compared at the level of nucleotide sequences. Nucleotide sequence comparisons are possible because all organisms share which of the following?Division of the nuclear chromosomesCellular organellesTypes of proteins needed for cellular functionsDNA bases30sB.6.B: Genetic Code
- Q4Four different types of cells are shown below. Which characteristic is shared by all four cells?A mechanism for transforming sunlight into energyGenetic material composed of DNAMembrane-bound organelles that transport substancesSelf-locomotion30sB.6.B: Genetic Code
- Q5The fact that a strain of yeast with a certain defective gene can use the human version of the gene to repair itself is evidence that yeast and humans —both have eukaryotic cellshave identical genomesshare a genetic codedepend on the same food supply30sB.6.B: Genetic Code
- Q6Scientists use zebra fish to study human genetic diseases because zebra fish and humans share many of the same genetic diseases. Which statement describes why zebra fish experience similar genetic diseases as humans?Zebra fish produce gametes through a process that is similar to that of humans.Zebra fish have nucleotide sequences similar to those of humans.Zebra fish have an omnivorous diet similar to that of humans.Zebra fish go through embryonic stages similar to those of humans.60sB.6.B: Genetic Code
