Worked Solution & Example Answer:Certain yeast (Saccharomyces cerevisiae) can be modified and made to express a human gene, resulting in the production of insulin - VCE - SSCE Biology - Question 36 - 2019 - Paper 1
Step 1
S. cerevisiae can most accurately be described as a
Answer
To determine the most accurate description of S. cerevisiae, we must consider the definitions of the terms provided:
-
Transgenic Organism: This refers to an organism that has been genetically modified to contain a gene from another species. Since S. cerevisiae has been modified to express a human gene, this description applies perfectly.
-
Yeast–Human Hybrid: This term typically refers to the direct fusion or hybridization between yeast and human cells, which does not accurately describe S. cerevisiae in this context.
-
Genetically Mutated Organism: While S. cerevisiae is genetically modified, the term 'mutated' might imply random mutations rather than intentional insertion of a human gene.
-
Laboratory-Produced Organism: Although S. cerevisiae is used in laboratories, this term is vague and does not accurately specify the genetic modification aspect.
Based on these evaluations, the most accurate description of S. cerevisiae is A. transgenic organism.
