What is the process called when DNA is converted into RNA?

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

Answer: (B)

Transcription is the process by which the information in DNA is copied into an RNA molecule. During transcription, RNA polymerase binds to a promoter on the DNA and reads one strand as a template, synthesizing a complementary RNA strand in the 5' to 3' direction. It uses ribonucleotides, so adenine pairs with uracil and cytosine pairs with guanine. This step creates RNA that can be used to make proteins or perform other functions. After transcription, RNA processing may occur in which introns are removed and exons joined to form mature mRNA in eukaryotes. Replication copies DNA into DNA, not RNA. Translation converts the RNA sequence into a protein, using ribosomes and tRNAs. Splicing is a later RNA-processing step, not the initial conversion from DNA to RNA.
