Detailed explanation-1: -anticodon – a sequence of three nucleotides on a tRNA molecule that bond to a complementary sequence on an mRNA molecule. The anticodon sequence determines the amino acid that the tRNA carries. DNA-the molecule that stores and encodes an organism’s genetic information.
Detailed explanation-2: -A codon is a specific sequence of nucleotides on an mRNA that corresponds to a specific amino acid or to a stop signal during protein translation. A nucleotide, in turn, is made up of a nucleobase (or simply, base), a sugar, and a phosphate group.
Detailed explanation-3: -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. AUG is the codon for methionine, and is also the start codon.
Detailed explanation-4: -Which BEST describes the importance of codons found in the sequence of DNA? They are used to assemble amino acids for protein synthesis.
