Plants, invertebrates and fungi rely on RNA interference to protect against virus infection since they do not produce interferon.

Question

Quizplus · Accepted Answer

Plants, invertebrates, and fungi lack the ability to produce interferon, which is an immune protein produced in response to viral infection in vertebrates. These organisms rely on RNA interference to protect against viral infection. RNA interference involves the introduction of small interfering RNAs (siRNAs) that target viral RNA, leading to its degradation and preventing viral replication.
