Ribosomal RNA (rRNA)
B
Transfer RNA (tRNA)
C
Small nuclear RNA (snRNA)
D
Messenger RNA (mRNA)
Verified step by step guidance1
Understand the role of each type of RNA in protein synthesis: Messenger RNA (mRNA) carries the genetic code from DNA to the ribosome; Ribosomal RNA (rRNA) forms the core of the ribosome's structure and catalyzes protein synthesis; Transfer RNA (tRNA) brings amino acids to the ribosome and matches them to the mRNA codons; Small nuclear RNA (snRNA) is involved in RNA splicing within the nucleus.
Focus on the process of translation, where the mRNA codons are read to assemble amino acids into a polypeptide chain.
Recognize that the RNA responsible for matching specific amino acids to the corresponding mRNA codons is transfer RNA (tRNA), which has an anticodon region complementary to the mRNA codon.
Recall that each tRNA molecule carries a specific amino acid and pairs with the mRNA codon through base pairing, ensuring the correct sequence of amino acids is formed.
Conclude that transfer RNA (tRNA) is the primary RNA type responsible for translating mRNA codons into an amino acid sequence during protein synthesis.
