Question

which carries the code for protein synthesis from the cell nucleus to the cytoplasm?
dna
trna
rrna
mrna

Explanation:

mRNA (messenger RNA) is transcribed from DNA in the nucleus and then carries the genetic code for protein - synthesis to the cytoplasm where translation occurs. DNA remains in the nucleus. tRNA (transfer RNA) helps in bringing amino - acids to the ribosome during translation. rRNA (ribosomal RNA) is a component of ribosomes.

Answer:

D. mRNA
