검증된 단계별 안내1
Understand the role of tRNA in protein synthesis: tRNA (transfer RNA) is responsible for bringing amino acids to the ribosome during translation, where proteins are synthesized.
Learn about the genetic code: The genetic code is composed of codons, which are sequences of three nucleotides (bases) on mRNA that correspond to specific amino acids.
Recognize the interaction between tRNA and mRNA: Each tRNA molecule has an anticodon that is complementary to a codon on the mRNA. This anticodon-codon pairing is crucial for the correct translation of the genetic code into proteins.
Identify the number of bases in a codon: A codon consists of three bases. Therefore, the anticodon on the tRNA must also consist of three bases to pair with the mRNA codon.
Conclude the number of bases read by tRNA: Since tRNA reads one codon at a time, and each codon is made up of three bases, tRNA reads three bases at one time.
