codons and anticodons

Detailed explanation-1: -In translation, the codons of an mRNA are read in order (from the 5’ end to the 3’ end) by molecules called transfer RNAs, or tRNAs. Each tRNA has an anticodon, a set of three nucleotides that binds to a matching mRNA codon through base pairing.
Detailed explanation-2: -Anticodons are found on molecules of tRNA. Their function is to base pair with the codon on a strand of mRNA during translation. This action ensures that the correct amino acid will be added to the growing polypeptide chain. A tRNA molecule will enter the ribosome bound to an amino acid.
Detailed explanation-3: -The key components required for translation are mRNA, ribosomes, transfer RNA (tRNA) and various enzymatic factors.
Detailed explanation-4: -The key components required for translation are mRNA, ribosomes, and transfer RNA (tRNA). During translation, mRNA nucleotide bases are read as codons of three bases. Each codon codes for a particular amino acid.
Detailed explanation-5: -In initiation, the ribosome assembles around the mRNA to be read and the first tRNA (carrying the amino acid methionine, which matches the start codon, AUG). This setup, called the initiation complex, is needed in order for translation to get started.
