Researchers Create a Transgenic Organism by Inserting a Gene from Algae

question 209

Multiple Choice

Researchers create a transgenic organism by inserting a gene from algae into corn.How do researchers make the algae gene function in corn?

• A) A regulatory sequence from corn DNA is joined to the coding sequence of the algae gene,and the resulting recombinant gene is inserted into the DNA of the corn.
• B) The algae gene is modified by joining it to an active corn gene using enzymes,and the resulting recombinant gene is incorporated into corn DNA.
• C) The chromosome containing the algae gene of interest is inserted into the nucleus of host corn cells where it is taken up into the corn chromosomes.
• D) The algae gene is incorporated into the corn DNA and then stimulated for expression through treatment with a chemical that activates protein synthesis.
• E) The regulatory and coding sequences of the algae gene are inserted into the corn gene,and specialized enzymes begin translation.
