What are the 8 process of protein synthesis?

What are the 8 process of protein synthesis?

Terms in this set (8) A messenger molecule called mRNA is formed. The messenger molecule (mRNA) reads the section of DNA. mRNA carries the copy out of the nucleus, through the cytoplasm, to the ribosome. Transfer molecules called tRNA bring the correct AA (amino acid) from the cytoplasm to the ribosome.

What are the steps in the process of 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 three steps: initiation, elongation, and termination.

What are the 5 stages of protein synthesis?

The five stages are: (1) Requirement of the Components (2) Activation of Amino Acids (3) Protein Synthesis Proper (4) Chaperones and Protein Folding and (5) Post-Translational Modifications of Proteins.

What are the steps in the protein synthesis process?

• All proteins are synthesized according to instructions contained in the DNA nucleotide sequence, which is unique to every individual • Protein synthesis is a two step process that consists of transcription and. translation.

Where does transcription take place in protein synthesis?

1. promoter, 2. transcription initiation, 3. 5′ upstream untranslated region, 4. translation start codon site, 5. protein-coding sequence, 6. translation stop codon region, 7. 3′ downstream untranslated region, and 8. terminator. Transcription takes place in three steps, called initiation, elongation, and termination.

Where are the amino acids transported during protein synthesis?

Step 3 — Transfer of Amino Acids to the Site of Protein Synthesis: During this step, the amino acids are transported from the amino acid pool to the ribosomes. But the amino acids occur in the cytoplasm in an inactive state. Each amino acid is activated by a specific activating enzyme known as amino acyl synthetase and ATP.

How are DNA triplets involved in protein synthesis?

Protein Synthesis: From Gene to Protein • Genes are stretches of nucleotides organized in triplets • Different arrangements or DNA triplets encode for each one of the 20 amino acids that make proteins • During transcription, a DNA triplet will produce an mRNA codon.
