Final answer:
The statement provided is false; gene expression involves transcription and translation, not the duplication of genes, which occurs during DNA replication.
Step-by-step explanation:
The statement 'Gene expression is the process of duplicating genes during DNA replication' is False. Gene expression involves transcription and translation. During transcription, a specific segment of DNA is used as a template to form messenger RNA (mRNA). This mRNA molecule then serves as the code for arranging amino acids in the correct order during translation, which is the process that synthesizes proteins. DNA replication is a separate process where the entire DNA molecule is copied to produce two identical DNA molecules. It's important to note that gene expression does not involve copying the entire DNA but rather using a gene's DNA sequence to produce an RNA transcript that guides protein synthesis.
Therefore, gene expression is the overall process of turning genetic information into functional products like proteins. This process includes steps such as transcription initiation, elongation, and termination. It's essential for the production of proteins, which are necessary for the structure, function, and regulation of the body's tissues and organs.
