What are the four basic steps in protein synthesis?
Transcription: DNA is first transcribed into mRNA in the nucleus. mRNA processing: The pre-mRNA is modified to become mature mRNA. Translation: mRNA is then translated into a specific amino acid sequence by ribosomes in the cytoplasm. Protein folding: The newly synthesized protein undergoes folding and may undergo post-translational modifications to become functional.
Uaa uga or uag codons found at the end of mrna?
UAA, UGA, and UAG are stop codons found at the end of mRNA sequences. When a ribosome encounters one of these stop codons during translation, it signals the end of protein synthesis and the release of the newly formed protein.
What happens to ribosomes during protein synthesis?
Ribosomes are the site of protein synthesis in the cell. They read the messenger RNA (mRNA) transcript and use it as a template to assemble amino acids into a polypeptide chain according to the genetic code. Ribosomes are composed of two subunits (small and large) that come together during translation and dissociate after protein synthesis is complete.
USS UGA or UAG codons found at the ends of mrna?
UAA, UAG, and UGA are stop codons that signal the end of protein synthesis. When they are reached on the mRNA, translation stops, and the completed protein is released from the ribosome.
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.
What happens at the end of translation?
the amino acids detach from the ribosome

What is the process of assembling a protein from RNA?
During translation, mRNA binds to ribosomes, and transfer RNA (tRNA) molecules bring amino acids to the ribosome according to the codons on the mRNA. The ribosome then catalyzes the formation of peptide bonds between amino acids, creating a chain that folds into a functional protein. This process repeats until a stop codon is reached, at which point the newly synthesized protein is released.
What is the order of how a cell changes DNA messages to protein?
DNA -> transcription -> pre-mRNA -> mRNA processing -> mRNA -> translation -> protein

Where is messenger RNA attached during protein construction?
Messenger RNA (mRNA) is attached to a ribosome during protein construction. The ribosome acts as the site where the mRNA is read and translated into a protein. As the ribosome moves along the mRNA, it synthesizes the corresponding protein based on the genetic information encoded in the mRNA molecule.
USS UGA or UAG codons found at the ends of mrna?
UAA, UAG, and UGA are stop codons that signal the end of protein synthesis. When they are reached on the mRNA, translation stops, and the completed protein is released from the ribosome.
Ribosome movement along the mRNA transcript is called?
Ribosome movement along the mRNA transcript is called translation. Translation is the process where the ribosome reads the mRNA sequence and synthesizes a corresponding protein by linking amino acids together in the correct order.

What is the portion of the protein molecule coded for by the pieces of mRNA?
The portion of the protein molecule that is coded for by mRNA is the sequence of amino acids. Each set of three nucleotides in the mRNA, called a codon, corresponds to a specific amino acid in the protein sequence. This process of translating mRNA into a protein is carried out by ribosomes during protein synthesis.
What does trna does that mrna does not have?
