Question

Which is the major difference between interkinesis and interphase?

• A. Only (I) and (II)
• B. Only (II) and (III)
• C. Only (I) and (III)
• D. (I), (II) and (III)

Hint:

\[ \boxed{\text{Interphase = growth + DNA replication}} \] \[ \boxed{\text{Interkinesis = no DNA replication}} \]

Answer 1

The Correct Option is D

Concept: Interphase is the long preparatory phase between two cell divisions, whereas interkinesis is a short resting phase between meiosis I and meiosis II.

Step 1: Understand interphase.
Interphase includes G1, S and G2 phases where DNA replication and cell growth occur. \[ \boxed{\text{Interphase → DNA replication + growth + organelle duplication}} \]

Step 2: Understand interkinesis.
Interkinesis occurs after meiosis I and before meiosis II. \[ \boxed{\text{Interkinesis → No DNA replication}} \]

Step 3: Key differences.

• DNA replication occurs in interphase but not in interkinesis.

• Interphase is long and active; interkinesis is short and inactive.

• Interphase occurs before mitosis/meiosis; interkinesis occurs only in meiosis.
Hence all statements (I), (II), and (III) are correct. \[ \boxed{\textbf{Option (D)}} \]
