Which nucleic acid carries amino acids to ribosomes?
|
|
mRNA
|
|
|
DNA
|
|
|
tRNA
|
|
|
rRNA

Explanation:
Detailed explanation-1: -tRNAs (transfer RNAs) carry amino acids to the ribosome. They act as “bridges, ” matching a codon in an mRNA with the amino acid it codes for.
Detailed explanation-2: -transfer RNA / tRNA Proteins are built from smaller units called amino acids, which are specified by three-nucleotide mRNA sequences called codons. Each codon represents a particular amino acid, and each codon is recognized by a specific tRNA.
Detailed explanation-3: -During protein synthesis, tRNAs with attached amino acids are delivered to the ribosome by proteins called elongation factors, which aid in association of the tRNA with the ribosome, synthesis of the new polypeptide, and translocation (movement) of the ribosome along the mRNA.
