Transfer RNA (tRNA)
from class: Microbiology Definition Transfer RNA (tRNA) is a type of RNA molecule that helps decode mRNA sequences into proteins. It carries amino acids to the ribosome, matching them with the appropriate codons on the mRNA strand during translation.
congrats on reading the definition of transfer RNA (tRNA) . now let's actually learn it.
Predict what's on your test 5 Must Know Facts For Your Next Test tRNA molecules have a characteristic cloverleaf structure with three hairpin loops. Each tRNA has an anticodon region that is complementary to an mRNA codon. Aminoacyl-tRNA synthetase enzymes attach specific amino acids to their corresponding tRNAs. The tRNA's 3' end attaches to an amino acid, forming an aminoacyl-tRNA complex. There are at least 20 different types of tRNAs, one for each amino acid.
