Copies information from DNA through base-pairing which molecule does this?

• A. tRNA
• B. rRNA
• C. mRNA
• D. DNA

Answer: (C)

Transcription is the process of copying genetic information from DNA into an RNA transcript. The molecule produced that carries this information to the ribosome for protein synthesis is messenger RNA, or mRNA. During transcription, RNA polymerase reads the DNA template and builds an RNA strand that is complementary to that template, using uracil in place of thymine. This means the mRNA sequence reflects the information encoded in DNA, ready to be read in units called codons by the ribosome during translation. The other two RNA types, tRNA and rRNA, play roles in assembling amino acids into proteins, but they do not serve as the direct copy of the DNA’s information. DNA remains the original template. In eukaryotes, transcription occurs in the nucleus, and the mRNA then travels to the cytoplasm to guide protein synthesis.
