✓ Correct answer: D. ReplicationDNA replication is the process by which a DNA molecule makes an identical copy of itself. This process occurs during cell division and is crucial for the transmission of genetic information from one generation to the next. Replication involves the unwinding of the DNA double helix, the separation of the two strands, and the synthesis of new complementary strands using the existing strands as templates. It is a highly accurate and tightly regulated process that ensures the faithful replication of genetic material.<br/><br/>Option A) Transformation: Transformation is a genetic process in which foreign DNA is introduced into a cell, resulting in the permanent alteration of the cell's genetic makeup. It is commonly used in genetic engineering and biotechnology.<br/><br/>Option B) Transcription: Transcription is the process by which the information stored in the DNA sequence is used to synthesize a complementary RNA molecule. It involves the synthesis of messenger RNA (mRNA) from a DNA template and is an important step in gene expression.<br/><br/>Option D) Reduction: Reduction is a chemical process that involves the gain of electrons or the loss of oxygen atoms. It is not directly related to the replication of DNA.
