Question

Explain the events that occrs in the host cells on introduce of nematodes resistant gene into tabacoo plant by using agrobacterium vectors

Answer 1

Answer:

Explanation:Double stranded RNA is produced endogenously or exogenously . Using Agrobacterium vectors nematode specific genes were introduced into the host plant (tobacco plant).Introduction of DNA produces both sse and antisense RNA in the host. These two RNA’s being complementary to each other formed a double stranded (dsRNA) that initiated RNAi.The dsRNA injected into the host plant from outside called exogenous dsRNA. The dsRNAs are cleaved into 21-23 segments (“small interfering RNAs”, or siRNAs) by an enzyme called Dicer.
