Which of the following statements about tRNA molecules is TRUE? Multiple Choice TRNA assumes a double helical shape Every base in a tRNA molecule pairs with another base in the same tRNA strand, leading to its higher levels of structure Bases in the tRNA loops do not pair with any other bases The amino acid is attached to the central loop region of the tRNA molecule All of the answers are correct.

Which statement about transfer RNA (TRNA) is NOT correct? Select one: O It folds up into the shape of an L. O It contains modified nucleotides. O It contains a codon at one end, and an anti-codon at the other end. O It is produced by transcription.

The initiator tRNA has the anticodon sequence It will base pair with the first AUG: Met: UAC Met: AUG; UAC O UAC: Met: AUG None of the above. and carries the amino acid. codon in the mRNA template.
