Biology Biotechnology Applications part 4 (Pest Resistance : RNA interference) class 12 XII

TL;DR

Genetic engineering techniques can be used to create pest resistant plants using RNA interference (RNAi) to silence specific mRNA molecules.

Transcript

hello friends this video on applications of biotechnology part 4 is brought to you by example.com no more fear from exam so let us now talk about the pest resistant plants so in the previous slide we talked about the insect resistant plants now we will see pest resistant plants nematodes act as parasite for many plants so i hope all of you remember...

Key Insights

• 🧑‍🏭 Nematodes act as parasites to plants, reducing crop yield and productivity in agriculture.
• 🌱 RNA interference (RNAi) is a genetic engineering technique that can be used to create pest resistant plants.
• 🤫 RNA interference involves blocking specific mRNA molecules, preventing their translation into proteins, and silencing their expression.
• 😑 Gene expression refers to the process of synthesizing functional gene products, such as proteins.
• 🤫 RNAi allows control over gene expression by selectively silencing specific mRNA molecules.
• 🤫 Silencing specific mRNA molecules prevents the translation of proteins corresponding to those mRNAs.
• 🌱 RNAi can be used to create plants that are resistant to pests by blocking genes associated with pest susceptibility.

Questions & Answers

Q: What is the role of nematodes in plants?

Nematodes act as parasites to many plants, living inside them and deriving nutrition from them, leading to reduced crop yield and productivity.

Q: How does RNA interference (RNAi) work in creating pest resistant plants?

RNA interference involves blocking specific mRNA molecules, preventing them from being translated into proteins. This silences the expression of genes related to pest susceptibility, creating plants that are resistant to pests.

Q: What is gene expression?

Gene expression refers to the process by which a gene's instructions are used to synthesize a functional gene product, such as a protein.

Q: How does RNAi regulate gene expression?

RNAi pathway regulates gene expression by selectively silencing specific mRNA molecules, preventing their translation into proteins. This allows control over which genes are expressed and which are not.

Summary & Key Takeaways

• Nematodes act as parasites to many plants, reducing crop yield and productivity in agriculture.

• RNA interference (RNAi) is a process used in genetic engineering to regulate gene expression and create pest resistant plants.

• RNA interference involves blocking specific mRNA molecules, preventing them from being translated into proteins and thus silencing their expression.
