- Q1The technique known as chromosome painting is the result of scientific research. Scientists use chromosome painting to mark the locations of genes on human chromosomes with fluorescent tags. It is also possible to apply this technique to the chromosomes of many different species. Chromosome painting allows for which of the following?The extraction of amino acids from different speciesAn increase in mutations in many speciesA comparison of the genomes of different speciesThe sequencing of proteins from many species30sBIOL.6b
- Q2The 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-Have identical genomesBoth have eukaryotic cellsShare a genetic codeDepend on the same food supply30sBIOL.6b
- Q3Four different types of cells are shown below. Which characteristic is shared by all four cells?Genetic material composed of DNAA mechanism for transforming sunlight into energyMembrane-bound organelles that transport substancesSelf-locomotion30sBIOL.6b
- Q4Organisms 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?Cellular organellesDNA basesDivision of the nuclear chromosomesTypes of proteins needed for cellular functions30sBIOL.6b
- Q5In 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?The genes for all organisms are composed of the same building blocks.The human body contains many types of bacteria, including E. coli.All living organisms share the same genome.Human cells are eukaryotic, and E. coli cells are prokaryotic.30sBIOL.6b
- Q6Which of these components are found in the cells of all living organisms?Hemoglobin and lymphocytesCellulose and chlorophyllEstrogen and testosteroneCytosine and guanine30sBIOL.6b
- Q7Scientists 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 go through embryonic stages similar to those of humanszebra fish have omnivorous diet similar to that of humansZebra fish have nucleotide sequences similar to those of humans30sBIOL.6b
- Q8Researches 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 -the replication of genetic material can occur at any temperaturesimilar nucleotides are present in both fruit fly and frog DNAheat can cause mutations in the DNA sequences of organismsfruit flies and frogs can be made to develop some of the same physical traits30sBIOL.6b
- Q9In the early 1980's 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?The genes fro all organisms are composed of the same building blocks.The human body contains many types of bacteria, including E. coli.Human cells are eukaryotic and E.coli cells are prokaryoticAll living organisms share the same genome30sBIOL.6b
