Question

A genetically engineered bacteria that is used for expressing a gene from a plant will

• A. Synthesize a protein with the same sequence of amino acids as in the plant and, therefore, the protein will have the same structure and function as in the plant.
• B. Synthesize a protein with essentially the same sequence of amino acids as in the plant with differences relating to different codon wobble rules between prokaryotes and eukaryotes.
• C. Not be able to synthesize a protein due to the presence of exon splicing sequences in the DNA sequence from the plant.
• D. Synthesize a protein with the same sequence of amino acids as in the plant but which mayor may not have a different shape or function due to differences in post transcriptional processing.
• E. Not be able to synthesize a protein due to the differences between prokaryote and eukaryote replication complexes in codon sequence recognition and amino acid polymerization.

Answer 1

Answer: (A)

Synthesize a protein with the same sequence of amino acids as in the plant and, therefore, the protein will have the same structure and function as in the plant.

DNA is universal. It means the genetic code remains the same for all organisms. This characteristic is critical to the success of genetic engineering. When a gene for a desirable trait is taken from one organism and inserted into another, it gives the recipient organism the ability to express that same trait.

The process of transformation is based on the physical removal of a gene from one organism and its insertion into another, which gives the recipient to produce the same protein encoded by the gene.
