Question

which part of translation is correctly paired with its definition?
a mrna: the rna molecule that carries amino acids and sugar with the cell
b mrna: the rna molecule that acts as the template for building a protein
c trna: the rna molecule that gives support to the protein being built
d trna: the rna molecule that transfers information between the r and the mitochondria

Explanation:

• mRNA (messenger RNA): It acts as a template for building a protein. During translation, ribosomes read the mRNA sequence and assemble amino acids accordingly.
• tRNA (transfer RNA): It transfers amino acids to the ribosome during protein synthesis.
• Option A: mRNA does not carry amino acids (tRNA does).
• Option C: tRNA does not give support to the protein (ribosomes and other factors are involved in protein structure support).
• Option D: tRNA transfers amino acids (not information between nucleus and mitochondria).

Answer:

B. mRNA: the RNA molecule that acts as the template for building a protein
