What is the process of adding new nucleotides to a growing DNA strand called?

• A. DNA Synthesis
• B. RNA Transcription
• C. Protein Translation
• D. Genetic Mutation

Answer: (A)

This is about DNA synthesis during DNA replication—the process by which a new DNA strand is built. DNA polymerase reads the template strand and adds complementary nucleotides to the growing strand, forming phosphodiester bonds at the 3' end. Base-pairing rules guide the pairing: A with T and G with C. The reaction uses energy from nucleotide triphosphates and typically starts at an RNA primer. One strand (the leading) is made continuously toward the replication fork, while the other (the lagging) is produced in short fragments that are later joined. The other options don’t describe building a DNA strand: transcription creates RNA from DNA, translation makes protein from RNA, and mutation is a change in the DNA sequence.
