Study Notes
tRNA vs mRNA
- tRNA (transfer RNA) plays a role in transcription, while mRNA (messenger RNA) is involved in translation.
- The structure of tRNA includes a three-leaf clover shape, while mRNA is a linear strand of nucleotides.
Function of tRNA
- tRNA's primary function is to decode mRNA sequences into specific amino acids during protein synthesis.
Anticodon
- An anticodon is a triplet of bases found on tRNA that can bind to complementary codons on mRNA.
- Each anticodon corresponds to a specific amino acid, which tRNA carries to the ribosome for protein synthesis.
Start Codon
- The codon AUG in mRNA typically signals the start of protein synthesis, marking the site where translation begins.
Formation of Proteins
- Amino acids are linked together by peptide bonds, forming polypeptides that fold into functional proteins.
Codon-Anticodon Interaction
- The mRNA codon CCA pairs with the tRNA anticodon GGU.
- This pairing delivers the amino acid associated with CCA to the growing polypeptide chain during translation.
Stop Codon
- A stop codon signals the termination of transcription, leading to the completion of protein synthesis.
