translation
Polypeptide chains are produced using messenger RNA (mRNA) as a template during the process of protein synthesis. The mRNA carries the code for the sequence of amino acids that make up the polypeptide chain.
The 2 basic steps of polypeptide synthesis are:Transcription - the synthesis of mRNA from a DNA template. Only one strand of DNA is copied, and a single gene may be transcribed thousands of times.Translation - the process where ribosomes synthesize proteins using the mature mRNA transcript produced during transcription. The ribosome attaches to mRNA, and then moves along the mRNA adding amino acids to the growing polypeptide chain.
Translation: the process of protein elongation & termination of protein synthesis. During protein synthesis the small and large ribosomal subunits join to form a functional ribose, durong this phase many processes take place. The result of these processes is protein elongation (polypeptide chain).
Messenger RNA (mRNA) directs the synthesis of a polypeptide at a ribosome by providing the instructions encoded in its nucleotide sequence for the order in which amino acids should be linked together to form the polypeptide.

The process of making protein is called protein synthesis. It involves the transcription of DNA into messenger RNA (mRNA) and the subsequent translation of mRNA into a polypeptide chain of amino acids.
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.
The amino acid that initiates protein synthesis is methionine. It serves as the starting point for the translation process, providing the first building block for the growing polypeptide chain.
That organic compound is called messenger RNA (mRNA). It carries the instructions from DNA to the ribosomes in the cell, where the synthesis of polypeptide chains occurs through the process of translation.
AUG is a "start codon" which initiates the process of translation in protein synthesis. It also carries the first amino acid of the polypeptide, methionine.
The codons are UAA,UAG and UGA
Amino acids are combined via peptide bonds to form a polypeptide so a 'polypeptide' is a chain of amino acids that have been linked together by dehydration synthesis.
