Match the deficiency conditions in Group I with the corresponding vitamin in Group II
Group I Group II
(P) Beriberi (1) Ascorbic acid
(Q) Scurvy (2) Retinol
(R) Birth defects (3) Thiamine
(S) Night blindness (4) Folic acid
Step 1: Understanding the deficiencies and their associated vitamins.
- Beriberi is caused by a deficiency in Thiamine (Vitamin B1).
- Scurvy is caused by a deficiency in Ascorbic acid (Vitamin C).
- Birth defects are often related to a lack of Folic acid (Vitamin B9).
- Night blindness is caused by a deficiency in Retinol (Vitamin A).
Step 2: Analyzing the options.
(A) P-3, Q-2, R-1, S-4: Incorrect — The correct pairings do not match here.
(B) P-2, Q-3, R-4, S-1: Incorrect — The vitamin pairings are wrong.
(C) P-3, Q-1, R-4, S-2: Correct — This correctly matches the deficiency conditions to their vitamins: - P (Beriberi) → Thiamine - Q (Scurvy) → Ascorbic acid - R (Birth defects) → Folic acid - S (Night blindness) → Retinol
(D) P-1, Q-2, R-3, S-4: Incorrect — This pairing is incorrect.
Step 3: Conclusion.
The correct answer is (C) P-3, Q-1, R-4, S-2.
Match List I with List II:
List I (Name of Vitamin)
Choose the correct answer from the options given below:
Identify the taxa that constitute a paraphyletic group in the given phylogenetic tree.
The vector, shown in the figure, has promoter and RBS sequences in the 300 bp region between the restriction sites for enzymes X and Y. There are no other sites for X and Y in the vector. The promoter is directed towards the Y site. The insert containing only an ORF provides 3 fragments after digestion with both enzymes X and Y. The ORF is cloned in the correct orientation in the vector using the single restriction enzyme Y. The size of the largest fragment of the recombinant plasmid expressing the ORF upon digestion with enzyme X is ........... bp. (answer in integer)
