Question

Which of the following statements about functional tRNAs are correct? Circle all that apply They contain many modified nucleosides About half their nucleosides are in base-paired helical regions They contain fewer than 100 ribonucleotides Their anticodons and amino acid accepting regions are within SAof each other They consist of two helical stems that are joined by loops to form a U-shaped structure They have a terminal AAC sequence at their amino acid accepting end Explain why tRNA molecules must have both unique and common structural features

Explanation / Answer

5). a). They contain many modified nucleosides.

e). They consists of two helical stems that are joined by loops to form a U-shaped structure

f). They have a terminal AAC sequence at their amino acid accepting end

6). Unique features are required for the aminoacyl-tRNA synthetases can distinguish among the tRNAs and attach the correct amino acid to the correct tRNA.
Common features are required bacause all tRNAs to interact with the same protein-synthesizing machinery.
