Assertion: Agrobacterium tumifaciens is popular in genetic engineering because this bacteriumis associated with the root nodules of all cereals and pulse crops. Reason: A gene incorporated in the bacterial chromosomal genome gets automatically transferred to the cross with which bacterium is associated.
Both assertion and reason are true. But reason is correct explanation of assertion.
Both assertion and reason are true. But reason is not correct explanation of assertion.
Assertion is true, but reason is false.
Assertion is false, but reason is true.
Both assertion and reason are false.

None of the above
Some of the characteristics of Bt cotton are
Long fibre and resistant to aphids
Medium yield, long fibre and resistant to beetle pests
high yield and production of toxic protein crystals which kill dipteran pests.
High yield and resistant to ball worms

Chapter 4: Principles and Processes of Biotechnology
Here you will find 16 MCQs questions and options. Read the questions carefully and select the appropriate answer for the question by selecting/clicking the box before the option. A pop-up box will open by displaying the result of the option selected. The result of each question will be based on percentages. Each question will have 3 chances to select the right option and for every chance, the percentage of scores will be reduced. Likewise, the remaining questions also take place. The overall percentage scored will be displayed at the completion of the mock test.
Note: Every time the page loads, the question and options will be randomized and takes you to the beginning of the particular exercise.
Button Navigations:
The Below Image shows the button navigations.
The Home Button On the Top and Bottom Navigates to the Homepage of the Subject (Example: To Bio - Botany if the mock test is taken from Bio - Botany).
The Next Chapter Button on the Top and Bottom Navigates to the Next Chapter (Example: From Chapter 4 to Chapter 5 and so on).
The Prev Chapter Button on the Top and Bottom Navigates to the Prev Chapter (Example: From Chapter 4 to Chapter 3 and so on).
The Next Button next to the question numbers Navigates to the Next Question (Example: From 1 to 2 and so on).
The Show All Questions Button Displays all the questions and options of that exercise on a single page.
The Option Box Icon (Box with Question mark icon), is the box that is to be selected for the correct option. By selecting/clicking the option box, a pop-up box will open by displaying the result of the option selected.
