What does a codon do in protein synthesis?

A codon is a sequence of three DNA or RNA nucleotides that corresponds with a specific amino acid or stop signal during protein synthesis. DNA and RNA molecules are written in a language of four nucleotides; meanwhile, the language of proteins includes 20 amino acids.

What are the 4 steps of translation?

Translation happens in four stages: activation (make ready), initiation (start), elongation (make longer) and termination (stop). These terms describe the growth of the amino acid chain (polypeptide).

What are the steps for protein synthesis?

Protein synthesis is the process in which cells make proteins. It occurs in two stages: transcription and translation. Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. It includes the steps of initiation, elongation, and termination.

What is the correct order of protein synthesis?

The correct sequence of events in protein synthesis is transcription, then translation.

What are the 5 steps of protein synthesis?

How many codons are needed for 3 amino acids?

Three codonsAnswer and Explanation: Three codons are needed to specify three amino acids.

What is the first step of translation?

Initiation (“beginning”): in this stage, the ribosome gets together with the mRNA and the first tRNA so translation can begin. Elongation (“middle”): in this stage, amino acids are brought to the ribosome by tRNAs and linked together to form a chain.

What does translation do in protein synthesis?

Translation occurs at the ribosome, which consists of rRNA and proteins. In translation, the instructions in mRNA are read, and tRNA brings the correct sequence of amino acids to the ribosome. Then, rRNA helps bonds form between the amino acids, producing a polypeptide chain.

What role do Trnas play in protein synthesis?

The overall role of tRNA in protein synthesis is to decode a specific codon of mRNA, using its anticodon, in order to transfer a specific amino acid to the end of a chain in the ribosome.

Where is an Anticodon found?

An anticodon is found at one end of a transfer RNA (tRNA) molecule. During protein synthesis, each time an amino acid is added to the growing protein, a tRNA forms base pairs with its complementary sequence on the mRNA molecule, ensuring that the appropriate amino acid is inserted into the protein.
