What does "transfer RNA" actually transfer?
- Group of answer choices
- Codons
- Amino acids
- Ribosome
- Transcripts
Solution
Transfer RNA (tRNA) actually transfers Amino acids.
Here's a step-by-step explanation:
- The process begins with the transcription of DNA into mRNA in the nucleus of the cell.
- The mRNA then travels out of the nucleus into the cytoplasm, where it attaches to a ribosome.
- Each mRNA molecule is made up of a sequence of nucleotides, which are read in groups of three called codons.
- Each codon corresponds to a specific amino acid.
- The tRNA's job is to carry the correct amino acid to the ribosome to be added to the growing protein chain.
- Each tRNA molecule has an anticodon that matches the codon on the mRNA.
- When the tRNA anticodon and mRNA codon match up, the tRNA deposits its amino acid and the ribosome moves on to the next codon.
- This process continues until the entire protein is synthesized.
So, in summary, transfer RNA (tRNA) transfers amino acids to the ribosome for protein synthesis.
