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

Only tRNA can come in contact with the ribosomes in the cytoplasm.

Explanation:

The mRNA is responsible for presenting the codons that will be read during translation, that is, it has the coded information for protein synthesis to take place. Given this property, it is easy to understand that these molecules vary greatly in size since proteins of different sizes exist. An mRNA can have from 500 to 6000 different nucleotides. Despite its great importance, mRNA is the least abundant type of RNA.

On the other hand, tRNA is responsible for promoting the transport of the correct amino acid for protein synthesis and is the only RNA that comes into contact with ribosomes in the cytoplasm. It stands out for its clover-like structure and is made up of about 70 to 90 nucleotides. All tRNAs have four characteristic arms, two of which are extremely important: the amino acid arm and the anticodon arm. The amino acid arm binds to the specific amino acid, while the anticodon has the complementary mRNA sequence.
