What process uses DNA as a template to synthesize RNA?

• A. Replication
• B. Translation
• C. Transcription
• D. Translocation

Answer: (C)

Understanding how genetic information is read to produce RNA is tested here. The process that uses DNA as a template to synthesize RNA is transcription. During transcription, RNA polymerase binds to a gene’s promoter, untwists a small DNA region, and reads the DNA template strand to assemble a complementary RNA strand in the 5' to 3' direction. The RNA sequence is complementary to the DNA template and uses uracil in place of thymine, so it resembles the gene’s coding sequence with U where T would be. This RNA transcript can then be processed into mRNA that carries the code to the ribosome for protein production. Replication copies DNA into DNA, not into RNA. Translation uses RNA to build proteins, not to make RNA. Translocation refers to movement events related to ribosomes or chromosomes, not RNA synthesis.
