The function of tRNA during protein synthesis is to __________.

The bonds that hold tRNA molecules in the correct three-dimensional shape are __________.

Which statement regarding the structure and function of tRNA is false?

The anticodon of a particular tRNA molecule is a. complementary to the corresponding mRNA codon. b. complementary to the corresponding triplet in rRNA. c. the part of tRNA that bonds to a specific amino acid. d. catalytic, making the tRNA a ribozyme.

Transfer RNA (tRNA)                   . a. carries monosaccharides to the ribosome for synthesis; b. is made of messenger RNA; c. has an anticodon region that is complementary to the mRNA codon; d. is the site of protein synthesis

A particular triplet of bases in the coding sequence of DNA is TGA. The anticodon on the tRNA that binds to the mRNA codon is                   . a. TGA; b. UGA; c. UCU; d. ACU

The nucleotide sequence of a DNA codon is GTA. A messenger RNA molecule with a complementary codon is transcribed from the DNA. In the process of protein synthesis, a transfer RNA pairs with the mRNA codon. What is the nucleotide sequence of the tRNA anticodon? a. CAT b. CUT c. GUA d. CAU
