What is the function of mRNA (messenger RNA) in protein synthesis?
Answer and explanation
Correct answer: B. Carrying the genetic code transcribed from DNA in the nucleus out to ribosomes in the cytoplasm for translation
- Step 1: mRNA is synthesized during transcription, complementary to the template DNA strand. Step 2. It exits the nucleus via nuclear pores and binds to ribosomes, where its codons specify the amino acid sequence of the protein. Answer: Carrying the genetic code transcribed from DNA in the nucleus out to ribosomes in the cytoplasm for translation. Why not the others: tRNA transfers amino acids, and DNA polymerase replicates DNA.
