All the terminator codons begin witha. Guanine b. Uracil c. Cytosine d. Adenine

Sure, here are the step-by-step solutions: Step 1: Recall that codons are three-nucleotide sequences that encode for specific amino acids or serve as stop signals during protein synthesis. Step 2: The three stop codons are UAA, UAG, and UGA. These codons signal to the ribosome that the protein synthesis process should terminate. Step 3: All three stop codons begin with the nucleotide uracil, which is represented by the letter U in RNA. Step 4: Therefore, the statement "All the terminator codons (UAA, UAG and UGA) begin with uracil" is true.
