question 9 of 10

which statement best describes the purpose of dna replication in cells?

a. a cell replicates its dna so that the dna can then be disassembled during the process of cell division.
b. a cell replicates its dna to increase genetic variation so that it can develop specialized functions.
c. a cell replicates its dna prior to division so that the two new cells have identical dna.
d. a cell replicates its dna after cell division to ensure that it has enough dna to perform life processes.

Explanation:

Analyze the question

The question asks for the statement that best describes the purpose of DNA replication in cells.

Evaluate Option A

Option A suggests DNA is replicated so it can be disassembled during cell division. This is incorrect because DNA is preserved and distributed, not disassembled.

Evaluate Option B

Option B states replication increases genetic variation for specialization. This is incorrect; DNA replication is highly accurate to copy genetic material exactly, while variation comes from other processes.

Evaluate Option C

Option C states a cell replicates its DNA prior to division so that the two new cells have identical DNA. This aligns with the core purpose of Cellular Division, ensuring genetic continuity.

Evaluate Option D

Option D suggests replication occurs after cell division. This is incorrect because replication must occur before division (during S phase of interphase) so each daughter cell receives a copy.

Answer:

• (A) A cell replicates its DNA so that the DNA can then be disassembled during the process of cell division.
• (B) A cell replicates its DNA to increase genetic variation so that it can develop specialized functions.
• (C) A cell replicates its DNA prior to division so that the two new cells have identical DNA. (Correct answer)
• (D) A cell replicates its DNA after cell division to ensure that it has enough DNA to perform life processes.
