Detailed explanation-1: -The three-letter nature of codons means that the four nucleotides found in mRNA-A, U, G, and C-can produce a total of 64 different combinations. Of these 64 codons, 61 represent amino acids, and the remaining three represent stop signals, which trigger the end of protein synthesis.
Detailed explanation-2: -It is the messenger RNA codon that carries the message specifying a certain amino acid; it is the transfer RNA that transfers that amino acid to the growing protein chain. The tRNA anticodon is a sequence of three nucleotides that are the complement of the three nucleotides in the mRNA codon.
Detailed explanation-3: -Codons are present on an mRNA or DNA. They are sequences of three nucleotides that code for a specific amino acid. Anticodons are present on the tRNA (transfer RNA) molecules that help transfer or bring in the amino acids to the mRNA during the translation process.
Detailed explanation-4: -Traditionally, the genetic code was represented by RNA codons, as it is messenger RNA (mRNA) that directs translation. Codons in the mRNA are decoded by transfer RNA (tRNA) during protein synthesis.
