A addition of an amino acid to a growing polypeptide chain is catalysed by tRNA b each tRNA molecule includes an anticodon fro one amino acid c tRNA is part of the ribosome d tRNA is produced in the endoplasmic reticulum e tRNA is required for transcription Correct. The anticodon arm is a 5-bp stem whose loop contains the anticodon.

Which of the following statements about tRNA is FALSE. A sequence in a tRNA that forms one side of a stem region can differ in sequence from one tRNA to another as long as another sequence elsewhere in the tRNA has been changed accordingly so as to retain complementarity. During translation in eukaryotes some ribosomes remain free inthe cytoplasm while others attach to protein channels embedded inthe RER.

A charged tRNA carries an amino acid at its 3 end. The anticodon within a tRNA has the same sequence as the codon in a mRNA Some tRNAs with different anticodons carry the same amino acid. Eukaryotic mRNA is processed in several ways before export out of the nucleus.

Although composed of a single strand of RNA each molecule contains several short double-helical regions. - Any particular tRNA binds to one and only one amino acid - tRNAs bind physically to mRNA - the three-dimensional structure of tRNA results from hydrogen bonding between complementary bases-tRNAs interact with ribosomes. BAlthough composed of a single strand of RNA each molecule contains several short double-helical regions.

A A C G and U are the only bases present in the molecule. C Any given tRNA will accept only one specific amino acid. The two-dimensional structure of tRNAs exhibits a cloverleaf pattern.

O an amino acid is covalently bonded to the 3 end of the tRNA. A Some of the enzymes have an editingproofreading capability. D The amino acid attachment is always to an A nucleotide at the 3 end of the.

A Ribosomes function as factories that coordinate the functioning of mRNA and tRNA. B The enzyme attaches an amino acid to the 3 end of a tRNA. Biology questions and answers.
