Verified step by step guidance1
Understand the role of each type of RNA in protein synthesis. Protein synthesis involves multiple types of RNA, each with a specific function.
mRNA (messenger RNA) carries the genetic information from DNA to the ribosome, where it serves as a template for assembling amino acids into a protein.
rRNA (ribosomal RNA) is a component of ribosomes, which are the cellular structures where protein synthesis occurs. It helps catalyze the formation of peptide bonds between amino acids.
snRNA (small nuclear RNA) is involved in the processing of pre-mRNA, including splicing, but does not directly participate in protein synthesis.
tRNA (transfer RNA) is responsible for carrying amino acids to the ribosome. Each tRNA molecule has an anticodon that pairs with a corresponding codon on the mRNA, ensuring the correct amino acid is added to the growing polypeptide chain.
