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.

What are the two basic steps of polypetide synthesis?
The two basic steps of polypeptide synthesis are transcription and translation. During transcription, the DNA is transcribed into messenger RNA (mRNA) in the nucleus. This mRNA then travels to the ribosome in the cytoplasm, where translation occurs, and the genetic code is used to assemble amino acids into a polypeptide chain, forming a protein.
What is the process of polypeptide synthesis?
translation
What are the 6 steps in protein synthesis simplied?
The steps in protein synthesis are: transcription, where DNA is copied into mRNA; mRNA processing, where the mRNA transcript is modified; translation, where the mRNA is read by ribosomes to synthesize a polypeptide; and post-translational modifications, folding, and transport of the protein to its functional location.
Which molecule directs the synthesis of a polypeptide at a ribosome?
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.
What chain is sequences of amino acids that is the foundation for the basic structure of a protein?
polypeptide chain
What codon starts polypeptide synthesis?
The codons are UAA,UAG and UGA
To what does the term polypeptide specifically refer?
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.
When does a polypeptide stop growing?
A polypeptide stops growing when the ribosome reaches a stop codon on the mRNA template. This triggers the release of the polypeptide chain, along with the ribosome and mRNA, from the protein synthesis machinery.
What does the term polypeptide specifically refer?
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.

What is the name given to the protein molecule when is consists of a basic polypeptide chain?
The protein molecule is called a polypeptide when it consists of a basic chain of amino acids. A polypeptide chain folds into a specific 3D structure to become a functional protein.
