Question

What is the complementary RNA pair that forms within the host plant cells during RNAi initiation?

Options

• mRNA and tRNA

• Coding and non-coding RNA

• rRNA and snRNA

• Sense and antisense RNA

Answer 1

The introduced DNA produces both sense and antisense RNA within the host cells. Because these two RNAs are complementary to each other, they pair up to form double-stranded RNA (dsRNA), which initiates the RNA interference process.
