Final answer:
Gene expression is false as it involves transcription and translation to synthesize proteins, not the duplication of genes which occurs during DNA replication.
Step-by-step explanation:
Gene expression is the process by which information from a gene is used to synthesize a functional gene product, typically a protein. This intricate process begins with transcription, where a segment of DNA is transcribed into messenger RNA (mRNA). Contrary to the idea of duplicating genes, transcription does not involve creating a copy of the DNA itself but rather creating an RNA sequence that is complementary to the DNA template. The mRNA then undergoes translation, where ribosomes read the sequence of the mRNA to construct the protein with the specific sequence of amino acids encoded by the gene.
It's important to distinguish between gene expression and DNA replication. DNA replication is the process of duplicating the entire DNA molecule, creating two identical DNA strands, before cell division. So, to answer the student question directly, the statement 'Gene expression is the process of duplicating genes during DNA replication' is false. Gene expression involves transcribing and translating a gene to make a protein, not duplicating the gene itself.
