Agrobacterium Mediated Transformation Quiz

What is the role of Ti plasmid in agrobacterium mediated transformation?

• Acts as a vector to transfer foreign DNA into plant cells

• Prevents foreign DNA from entering plant cells

• Provides nutrients to plant cells

• Causes mutation in plant cells

How does the Ti plasmid contribute to the transfer of genes into plant cells?

• It contains T-DNA which is transferred into animal cells by Agrobacterium.

• It contains T-DNA which is transferred into plant cells by viruses.

• It contains T-DNA which is transferred into plant cells by fungi.

• It contains T-DNA which is transferred into plant cells by Agrobacterium.

Why is the selection of plant tissue important in agrobacterium mediated transformation?

• It determines the success of the transformation process and the ability of the plant cells to regenerate into whole plants.

• The selection of plant tissue only affects the color of the transformed plants

• The plant tissue type does not affect the ability of the plant cells to regenerate

• It has no impact on the transformation process

What are the factors to consider when selecting plant tissue for transformation?

• Type of plant, stage of development, ability to regenerate

• Color of the plant, size of the leaves, type of soil

• Number of petals, height of the plant, smell of the flowers

• Age of the gardener, type of pot, color of the plant

What are the different types of Agrobacterium strains used in transformation?

• Golden Rice, Purple Corn, Silver Wheat

• LBA4404, GV3101, EHA105, AGL1, and C58C1

• Red Tomato, Green Pepper, Yellow Potato

• Roundup Ready, Liberty Link, Bt Cotton

How do the different types of Agrobacterium strains affect the transformation process?

• By influencing the height of the plant stems

• By affecting the color of the plant leaves

• By changing the taste of the plant fruits

• By varying in their ability to transfer DNA into plant cells.

What are the optimal co-cultivation conditions for successful transformation?

• Young, actively growing plant tissues, proper pH level, and appropriate temperature and light conditions

• Inappropriate temperature and light conditions

• Extreme pH level

• Old, withering plant tissues

How do co-cultivation conditions impact the efficiency of agrobacterium mediated transformation?

• By affecting the interaction between the plant tissue and the agrobacterium, as well as the transfer of T-DNA into the plant cells.

• By increasing the resistance of the plant tissue to agrobacterium

• By improving the efficiency of chemical transformation

• By decreasing the transfer of T-DNA into the plant cells

What factors can affect the efficiency of agrobacterium mediated transformation?

• Weather conditions, time of day, and soil pH

• Plant species, Agrobacterium strain, type of tissue, and co-cultivation conditions

• Number of leaves, plant height, and flower color

• Type of fertilizer, watering frequency, and pot size

How can these factors be optimized to improve transformation efficiency?

• By selecting unhealthy plant tissue for transformation

• By reducing the duration of co-cultivation

• By increasing the concentration of herbicides

• By adjusting the concentration of Agrobacterium, the duration of co-cultivation, and the selection of appropriate plant tissue for transformation.
