Question

what is the primary purpose of dna being copied in cells? to create new proteins to eliminate waste to increase cell size to facilitate cell division

Explanation:

DNA replication occurs before cell division to ensure each new cell gets a complete set of genetic information. Protein - creation involves transcription and translation of DNA, not just its replication. Eliminating waste and increasing cell size are not the main purposes of DNA copying.

Answer:

"To facilitate cell division"
