Question

Choose the correct statements among the following: A) Meiosis involves pairing of homologous chromosomes and recombination B) Crossing over is enzyme mediated process C) During diakinesis terminalization takes place D) Interkinesis is the stage between prophase I and prophase II

• A. A, C, D
• B. A, B, D
• C. B, C, D
• D. A, B, C

Hint:

Interkinesis is a short-lived phase between Meiosis I and II, not between Prophase I and II.

Answer 1

The Correct Option is D

Step 1: Set the scene.
Meiosis is a special cell division that makes four cells, each with half the chromosome number. We must judge four statements about it.

Step 2: Test statement A.
During meiosis, matching (homologous) chromosomes pair up and swap parts, which is called recombination. This is true, so A is correct.

Step 3: Test statement B.
Crossing over is carried out with the help of enzymes such as recombinase. So it is an enzyme-mediated process, and B is correct.

Step 4: Test statement C.
During the diakinesis stage, the points where chromosomes joined (chiasmata) move toward the ends, called terminalization. So C is correct.

Step 5: Test statement D.
Interkinesis is the short rest stage between Meiosis I and Meiosis II, not between prophase I and prophase II. So D is false.

Step 6: Choose the right set.
The correct statements are A, B, and C, so the answer is A, B, C.
\[ \boxed{\text{A, B, C}} \]
