CUET PG Life Sciences (SCQP17) Memory-Based Questions

1) What is the function of Mercury Chloride?

Ans: Mercury chloride (HgCl₂)

2) Select two inorganic nitrogen sources for nitrogen fixation in plants.

Ans: Nitrate (NO₃⁻), Ammonium (NH₄⁺)

3) If a sequence has the initiator codon AUG, which codes for methionine, then:

• Statement I: Yes, the translation process starts with methionine (AUG is the universal start codon).
• Statement II: Methionine may or may not be present in the final protein, as it can be cleaved during post-translational modifications.

4) Typhoid Vi vaccine consists of which type of product?

Ans: Bacterial product.

5) Arrange the sequence of bacterial transcription

• Initiation – RNA polymerase binds to the promoter region.
• Elongation – RNA polymerase synthesizes the RNA strand.
• Termination – The transcription process stops, and RNA polymerase is released.

6) Which one is termed as the "guardian of the genome"?

Ans: p53

7) Match the following:

A. Polymers – DNA, RNA

B. Polymerase – DNA polymerase, RNA polymerase

Ans:

• DNA Polymerase → DNA synthesis
• RNA Polymerase → RNA synthesis (transcription)

8) If a flower is cut vertically, what is this type of section called?

Ans: A longitudinal section (LS) is the vertical cut of a flower, showing its internal structure from top to bottom.

9) What is the function of Histatin?

Ans: Histatins are antimicrobial peptides found in saliva. They help in wound healing, inhibit fungal growth (especially Candida albicans), and maintain oral health.

10) What is convalescent serum?

Ans: Convalescent serum is a blood serum obtained from individuals who have recovered from an infection. It contains antibodies against the pathogen and can be used as passive immunotherapy to treat or prevent infections.

11) In the F1 generation (RrIi), if recessive genes are crossed, how many zygotes will form?

Ans: If the F1 generation genotype is RrIi (dihybrid cross), crossing two heterozygous individuals follows the dihybrid cross ratio (Punnett square analysis). The total number of possible zygotic combinations is: 16 zygotes (based on the 4×4 Punnett square).

CUET PG Mock Tests 2025

The CUET PG Life Sciences Mock Tests 2025 are designed to assist candidates in becoming accustomed to the exam pattern and building their preparation. The mock tests replicate the real exam setting, enabling aspirants to practice subject-related questions, enhance time management, and determine areas requiring greater attention. Detailed solutions and performance analysis will be provided to assist candidates in fine-tuning their strategies for improvement.

Importance of Mock Tests during Preparation

• Knowledge of Exam Pattern: Facilitates understanding of the pattern, question types, and marking scheme related to Life Sciences.

• Time Management Skills: Allows aspirants to practice and finish the exam in the provided time, enhancing speed and accuracy.

• Weak Areas Identification: Puts focus on subject-specific topics requiring extra emphasis, enabling intense revision.

• Improves Confidence: Develops confidence by offering a real exam like simulation, avoiding anxiety at the time of the actual exam.

• Application of Concepts: Enables candidates to implement theoretical concepts in a real environment, solidifying learning.

• Performance Analysis: Offers insights through step-by-step solutions and analysis, enabling candidates to refine their preparation strategy.

Time Management Tips for the Exam

• Understand Section-wise Weightage: Concentrate on high-weightage subjects such as to plan time accordingly.

• Set Time Limits for Each Section: Split the time available as per the number of questions and difficulty level in each section.

• Prioritize Easy and High-scoring Questions: Solve easy questions first to grab marks promptly and then shift to hard or long questions.

• Avoid Wasting Too Much Time on a Single Question: If a question appears to be time-consuming, skip it and come back to it later if there's time available.

• Save Time for Review: Set aside 5-10 minutes at the end to look over answers and correct them if needed.

Mistakes to Avoid During Preparation

• Overlooking Key Topics: Neglecting key topics like Techniques, Chromatin Structure and Function, Biochemistry and Biotechnology can lead to missing out on important marks.

• Dependence on Theory Alone: Avoid focusing solely on theoretical aspects without practising numerical questions.

• Missing Mock Tests: Not taking enough mock tests can lead to poor time management and a lack of familiarity with the exam pattern.

• Lack of Revision: Failure to revise key concepts periodically can lead to the loss of required information while taking the exam.

• Overloading with Multiple Resources: Going through multiple books or study materials can lead to confusion and impact rigorous preparation.
