Free online mock test for Biotechnology: Principles and Processes (ICSE Class 10 Zoology) — 74 competency-based questions based on the latest CISCE 2027 syllabus, with instant marking. Try the samples below, then take the full test free.
What to expect: This mock test covers key concepts from the Biotechnology: Principles and Processes chapter — including application-based and competency-focused questions aligned with how ICSE actually sets the paper.
Tip: Attempt without notes first to identify gaps, then review explanations for any wrong answers. Retake after a few days for best retention.
Sample questions
-
1.Negatively charged DNA fragments produced by restriction digestion are separated according to size by:
- A.Gel electrophoresis
- B.Centrifugation
- C.Chromatography on a column
- D.Spooling on a glass rod
-
2.Arrange the steps of separating and recovering DNA fragments after restriction digestion: (P) Elution from the gel piece (Q) Staining with ethidium bromide (R) Loading and running on agarose gel (S) Visualising orange bands under UV.
- A.R, Q, S, P
- B.Q, R, S, P
- C.R, S, Q, P
- D.P, R, Q, S
-
3.In the naming convention for restriction enzymes, in EcoRI from Escherichia coli RY13, the Roman numeral 'I' indicates:
- A.The order in which the enzyme was isolated from that strain
- B.The number of base pairs recognised
- C.The number of copies per cell
- D.The number of sticky ends produced
-
4.Assertion (A): A thermostable DNA polymerase is used in PCR. Reason (R): The enzyme, isolated from the bacterium Thermus aquaticus, remains active during the high temperature induced denaturation of double-stranded DNA.
- A.Both A and R are true and R is the correct explanation of A
- B.Both A and R are true but R is NOT the correct explanation of A
- C.A is true but R is false
- D.A is false but R is true
-
5.In the exercise Explain briefly PCR, the molecules that are required to be complementary to the regions of DNA being amplified are the:
- A.Primers (small chemically synthesised oligonucleotides)
- B.Restriction enzymes
- C.Ligases
- D.Plasmids
