Charged tRNA
from class: Microbiology Definition Charged tRNA, also known as aminoacyl-tRNA, is a tRNA molecule that is covalently bonded to its corresponding amino acid. This charging process is essential for the addition of amino acids during protein synthesis.
congrats on reading the definition of charged tRNA . now let's actually learn it.
Predict what's on your test 5 Must Know Facts For Your Next Test Charged tRNA is essential for translating mRNA codons into a specific amino acid sequence in proteins. The enzyme aminoacyl-tRNA synthetase catalyzes the attachment of an amino acid to its corresponding tRNA. Each type of tRNA has a specific anticodon that pairs with a complementary mRNA codon during translation. There are at least 20 different types of aminoacyl-tRNA synthetases, one for each amino acid. Incorrect charging of tRNAs can lead to errors in protein synthesis and potentially nonfunctional or harmful proteins. Review Questions What role does charged tRNA play in protein synthesis? Which enzyme is responsible for attaching an amino acid to its corresponding tRNA? How does the anticodon of charged tRNA relate to mRNA during translation? "Charged tRNA" also found in:
