Question

which molecule copies code from the nucleus and delivers it to ribosomes? trna amino acids mrna dna

Explanation:

• tRNA: Transfers amino acids to ribosomes during translation, not for copying nuclear code.
• Amino acids: Building blocks of proteins, not involved in copying and delivering nuclear code.
• mRNA: During transcription, mRNA is synthesized from DNA in the nucleus, carrying the genetic code. It then moves to ribosomes where translation (protein synthesis) occurs.
• DNA: Stores genetic information in the nucleus but does not directly deliver code to ribosomes.

Answer:

C. mRNA
