Biology Review Questions 8-11

The 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 

• depend on the same food supply
• Share a genetic code
• both have eukaryotic cells
• have identical genomes

In all three complex carbohydrates, the subunits or glucose are bonded together differently. Because they have different structures, they most likely

• contain different chemical elements
• form dilferent proteins
• carry different nucleotides
• perform different frunctions

In 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 prokaryotic.
• All living organisms snare the same genome.
• The genes for all organisms are composed of the same building blocks.
• The human body contains many types or bacteria, Including E. coli.

This process ls an example of which of the following

• The role of the endocrine system In Increasing the oxygen content of red blood cells
• Control of urine production by the parasympathetic nervous system
• Maintenance of homeostasis by a feedback mechanism
• Disruption of homeostasis by exercise
