Can you suggest a method to remove oil (hydrocarbon) from seeds based on your understanding of rDNA technology and chemistry of oil?
Based on rDNA technology, oil can be removed from seeds through genetic manipulation of the plant's metabolic pathways.
Genetically Modified Organisms (GMO) technology allows us to alter genes in plants. One approach involves using RNA interference (RNAi) to silence specific mRNA responsible for oil biosynthesis in seeds. Using Agrobacterium vectors, genes can be introduced into the host plant that produce both sense and anti-sense RNA complementary to oil-producing genes. These complementary RNA strands form double-stranded RNA (dsRNA) that binds to and prevents translation of the target mRNA, thereby silencing the genes responsible for oil production.
This method of gene silencing could significantly reduce or eliminate oil content in seeds, making oil extraction or seed processing more efficient for various industrial applications.
Explanation
The provided context discusses RNA interference (RNAi) as a method where dsRNA binds to and prevents translation of specific mRNA, effectively silencing genes. The context also mentions Agrobacterium vectors being used to introduce genes into host plants, and the concept of creating Genetically Modified Organisms (GMO). While the context doesn't specifically address oil removal, the student is expected to apply these rDNA technology concepts to suggest a method. The answer applies the RNAi mechanism described for nematode resistance to the concept of silencing oil biosynthesis genes.
Solution Steps
Step 1: Identify that oil/hydrocarbon synthesis in seeds is controlled by specific genes
Step 2: Apply RNAi concept - use Agrobacterium vectors to introduce genes producing complementary dsRNA
Step 3: The dsRNA silences mRNA responsible for oil production, reducing/eliminating oil in seeds
