Chapter 11: Programming and Systems Biology — Important Questions & Answers (FAQ)

Frequently asked questions from CBSE(NCERT) Grade 11 BIOTECHNOLOGY — Chapter 11: Programming and Systems Biology, with answers and explanations. These are sample questions; the exam has its own separate question set.

What is the main purpose of systems biology in biotechnology?

A. To study genes only in isolation
B. To understand interactions among biological components as a whole system ✓
C. To replace laboratory experiments completely
D. To classify organisms only by shape

Answer: B. To understand interactions among biological components as a whole system
Systems biology focuses on the interactions among genes, proteins, metabolites, and other components to understand the behavior of the entire biological system.

Which of the following is an example of a biological network?

A. Food pyramid
B. Gene regulatory network ✓
C. Chromosome banding pattern
D. Cell wall structure

Answer: B. Gene regulatory network
A gene regulatory network shows how genes control each other's expression, which is a key example of a biological network.

Which of the following best describes an advantage of computational modeling in biology?

A. It eliminates the need for any biological data
B. It helps test hypotheses before performing expensive experiments ✓
C. It works only for plants
D. It can only be used for visual diagrams

Answer: B. It helps test hypotheses before performing expensive experiments
Computational models allow scientists to explore possible outcomes and test ideas before carrying out time-consuming experiments.

A researcher notices that changing one gene in a network affects several other genes. What does this best suggest?

A. Genes act independently in all cases
B. Biological systems are interconnected and dynamic ✓
C. DNA has no role in regulation
D. Only proteins influence cell behavior

Answer: B. Biological systems are interconnected and dynamic
In systems biology, changing one component can influence many others because biological systems are interconnected.

In a model of a metabolic pathway, if the output remains almost unchanged even when one enzyme is reduced, the most likely explanation is:

A. The pathway has no regulation
B. Other components may compensate due to network robustness ✓
C. The model must be completely wrong in all cases
D. The enzyme has turned into DNA

Answer: B. Other components may compensate due to network robustness
Biological systems often show robustness, meaning other pathway components can buffer the effect of a change in one part.
