In which of the following ways are trna and mrna different? a. the mrna repairs mistakes in the dna while trna repairs proteins. b. only trna bends into a shape that can carry specific amino acids. c. only trna can come in contact with the ribosomes in the cytoplasm. d. the mrna uses uracil while the trna uses thymine in its place.

The correct option is C.
The tRNA is the only type of RNA that can come in contact with the ribosomes in the cytoplasm. During the translation process of protein synthesis in the cell, the tRNA function by carrying amino acid to the ribosomes and matching the codon in the mRNA with the amino acid it codes for. Thus it acts as a bridge between mRNA and ribosomes.
