What is the process of copying DNA segments into messenger RNA called?

• A. DNA Transcription
• B. Translation
• C. Replication
• D. Transduction

Answer: (A)

Transcription is the process of copying DNA segments into messenger RNA. During transcription, RNA polymerase reads a DNA template and builds a complementary RNA molecule, with uracil replacing thymine. The resulting mRNA carries the genetic message from the DNA in the nucleus to ribosomes in the cytoplasm, where it guides protein synthesis. This is distinct from replication, which copies DNA to DNA for cell division, translation, which uses mRNA to assemble amino acids into a protein, and transduction, which refers to transfer of genetic material by a virus or other vectors.
