Question

which best explains why dna replication in the human body is significant?
o it is needed for cell division
o it is necessary for protein synthesis
o it replaces any damaged dna cells
o it produces rna strands

Explanation:

DNA replication is crucial for cell division. During cell division, a cell needs to pass on its genetic information to the new daughter cells. DNA replication ensures that each new cell gets a complete set of DNA. Protein synthesis uses RNA (not directly related to the main significance of DNA replication here). While DNA can be repaired (not the main focus of why replication is significant), and RNA strands are produced in transcription (not the key for DNA replication's significance). The core is that for cell division to occur properly, DNA must replicate so that each new cell has the genetic material.

Answer:

it is needed for cell division
