Answer:
The correct statements are statement 3 and 4.
Explanation:
An alignment of three nucleotides within the RNA or DNA that assists in coding a specific amino acid or instructs the cell to either cease or begin the synthesis of protein is termed as a codon. A sum of 64 probable codons are found that comprise three of the four possible nucleotides, however, only 20 amino acids are present in the majority of the biological species.
The given third statement is true as there are some of the codons known as stop codons that plays an essential role in terminating the process of protein synthesis.
The given fourth statement is also true as codons known as stop codons are not identified by tRNAs, they are identified by ribosomes.
