Question

multiple choice / points gene expression in all organisms depends on protein synthesis. what is the last stage in protein synthesis, in which amino acids are assembled by trna? replication assembly translation transcription multiple choice 8 points translation and protein synthesis is occurring at the ribosome. if the trna anticodon being matched at the ribosome is aug, what would be the matching mrna codon? tag aug tac uac

Explanation:

1. In protein synthesis, transcription is the first - stage where DNA is copied into mRNA. Translation is the last stage where tRNA assembles amino acids according to the mRNA sequence. Replication is related to DNA duplication, not the last stage of protein synthesis. Assembly is a general term and not the specific last stage term.
2. In translation, the tRNA anticodon pairs with the mRNA codon. Adenine (A) in tRNA pairs with Uracil (U) in mRNA, and Guanine (G) in tRNA pairs with Cytosine (C) in mRNA. So if the tRNA anticodon is AUG, the mRNA codon is UAC.

Answer:

1. C. translation
2. D. UAC
