Question

which of the following transfers amino acids present in the cytoplasm to the ribosomes?
multiple choice
trna
mrna
dna
rrna
protein

Explanation:

• tRNA (Transfer RNA): It has an anticodon loop that base - pairs with the codon on mRNA and an amino - acid attachment site. It specifically binds to amino acids in the cytoplasm and transports them to the ribosomes for protein synthesis.
• mRNA (Messenger RNA): Carries the genetic information from DNA (in the nucleus) to the ribosomes. It provides the template for protein synthesis but does not directly transfer amino acids.
• DNA (Deoxyribonucleic Acid): Stores the genetic information. It is mainly located in the nucleus (in eukaryotes) and does not directly participate in the transfer of amino acids to ribosomes.
• rRNA (Ribosomal RNA): Along with proteins, makes up the ribosomes. It is involved in the catalytic and structural aspects of protein synthesis but not in amino - acid transfer.
• Protein: Is the end - product of protein synthesis (formed by the polymerization of amino acids at the ribosomes) and not involved in the transfer of amino acids.

Answer:

tRNA
