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⁺)

• 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).
