Amino acids are added to the growing polypeptide strand during protein synthesis. Ribosomes facilitate the process by reading the mRNA and catalyzing the formation of peptide bonds between the amino acids. This results in the elongation of the polypeptide chain until a stop codon is reached.
Amino acids are linked together to form proteins as the ribosome moves along the mRNA transcript. Transfer RNA molecules bring specific amino acids to the ribosome, where they are added to the growing protein chain based on the mRNA codons being read. This process continues until a stop codon is reached, leading to the completion of protein synthesis.
A proteinAnswerMore correctly, a chain of amino acids is called a polypeptide. A protein may be a single polypeptide or many polypeptides wound up together and associated with themselves and with one another through secondary, tertiary and quaternary structures.
mRNA
There are 64 possible triplets. At least one of the triplets needs to be a stop codon, so theoretically 63 different amino acids can be coded for. In practice, there's some redundancy, and in humans all codons are either stop codons or translate to one of twenty amino acids.

mRNA
Stop codons (also known as nonsense codons) do not code for amino acids. These include UAG, UAA, and UGA. When a stop codon is encountered during translation, it signals the termination of protein synthesis.
The three codons that do not carry amino acids are UAA, UAG, and UGA. These codons are known as stop codons and signal the end of protein synthesis.
The genetic code, which is translated by the ribosome during protein synthesis, specifies the sequence in which amino acids are added to the growing polypeptide chain. Each three-nucleotide codon on the mRNA corresponds to a specific amino acid, ensuring that the correct amino acids are added in the correct order. Factors such as tRNAs, aminoacyl-tRNA synthetases, and ribosomal machinery also play key roles in ensuring accurate sequencing.
amino acid
There are 20 standard amino acids that are considered to be the building blocks of proteins.
They signal to stop protein synthesis and release the amino acid chain. Stop codons are important because they signal the end of synthesis. Sometimes, mRNA is longer than what is needed for the amino acids so without stop codons, synthesis would continue until the end of the strand of RNA, leaving you with an incorrect amino acid chain.
61 codons specify the amino acids used in proteins and 3 codons (stop codons) signal termination of growth of the polypeptide chain...so 64 total
