Question

which nucleic acid moves the code for protein synthesis from the nucleus to the ribosomes?
trna
rrna
mrna
drna

Explanation:

To determine which nucleic acid moves the code for protein synthesis from the nucleus to the ribosomes, we analyze the functions of each option:

• tRNA (transfer RNA): Its role is to transfer amino acids to the ribosome during protein synthesis, not to carry the genetic code from the nucleus.
• rRNA (ribosomal RNA): It is a component of ribosomes and is involved in the structure and catalytic functions of ribosomes, not in transporting the code from the nucleus.
• mRNA (messenger RNA): mRNA is transcribed from DNA in the nucleus and carries the genetic information (the code for protein synthesis) from the nucleus to the ribosomes in the cytoplasm, where translation (protein synthesis) occurs.
• dRNA: This is not a commonly recognized type of RNA involved in protein synthesis, and there is no established role for "dRNA" in transporting the code for protein synthesis from the nucleus to ribosomes.

Answer:

mRNA
