Detailed explanation-1: -A codon table can be used to translate a genetic code into a sequence of amino acids. The standard genetic code is traditionally represented as an RNA codon table, because when proteins are made in a cell by ribosomes, it is messenger RNA (mRNA) that directs protein synthesis.

Detailed explanation-2: -Genetic code table. Each three-letter sequence of mRNA nucleotides corresponds to a specific amino acid, or to a stop codon. UGA, UAA, and UAG are stop codons.

Detailed explanation-3: -There are two main methods used to find the amino acid sequences of proteins. Mass spectrometry is the most common method in use today because of its ease of use. Edman degradation using a protein sequenator is the second method, which is most useful if the N-terminus of a protein needs to be characterized.

Detailed explanation-4: -The transfer RNA (tRNA) is one type of RNA molecule. Its job is to carry the amino acid that matches the mRNA codon to the ribosome. The tRNA contains a three-letter code on one side and carries a specific amino acid on the other side.
