Match the following:
List-1 | List-2 |
A. Interferons B. Immunoglobulin II. C. Interleukins III. D. Tc - lymphocytes IV. | I. Leucocytes II. Perforins III. Antiviral proteins IV. Paratope V. Lysozyme |
1. A-III, B-IV, C-V, D-II
2. A-II, B-I, C-IV, D-III
3. A-IV, B-II, C-I, D-V
4. A-IV, B-III, C-I, D-I
We are required to match the items from List I with those from List II.
Step 1: Let's analyze each option. Interferons are antiviral proteins that inhibit the replication of viruses, matching with option III.
Immunoglobulins are antibodies and are involved in recognizing foreign antigens and are associated with the paratope, so it matches with IV. Interleukins are proteins that stimulate immune cells such as T-cells and leukocytes, so they match with I. \item Tc-lymphocytes are associated with the production of perforins, which are cytotoxic proteins, so they match with II.
Thus, the correct answer is: (A) III, (B) IV, (C) I, (D) II.
Pure-tall (TT) pea plants are crossed with pure-dwarf (tt) pea plants. The pea plants obtained in F1 generation are then self-pollinated to produce F2 generation.
(i) What do the plants of F1 generation look like? Justify your answer.
(ii) What is the ratio of pure-tall plants to pure-dwarf plants in F2 generation?
Proteins control the expression of various characters. Explain this statement by taking an example of "tallness" as a characteristic in plants
