How does mRNA play a role in protein synthesis?
| Step | Action | Novel Insight | Risk Factors |
|---|---|---|---|
| 1 | Transcription | RNA polymerase binds to the promoter region of a gene and separates the DNA strands. | Mutations in the promoter region can affect the binding of RNA polymerase and lead to decreased gene expression. |
| 2 | mRNA processing | Introns are removed from the pre-mRNA molecule and the remaining exons are spliced together. A 5′ cap and a 3′ poly-A tail are added to the mRNA molecule. | Errors in splicing can lead to the inclusion of introns in the final mRNA molecule, which can affect the translation process. |
| 3 | Translation initiation | The mRNA molecule binds to a ribosome, and the start codon (AUG) is recognized by the initiation complex. | Mutations in the start codon can lead to incorrect initiation of translation and the production of non-functional proteins. |
| 4 | Translation elongation | tRNA molecules carrying specific amino acids bind to the codons on the mRNA molecule, and the ribosome catalyzes the formation of peptide bonds between the amino acids. | Errors in tRNA charging or ribosome function can lead to incorrect amino acid incorporation and the production of non-functional proteins. |
| 5 | Translation termination | When a stop codon (UAA, UAG, or UGA) is reached, the ribosome releases the polypeptide chain and the mRNA molecule. | Mutations in the stop codon can lead to premature termination of translation and the production of truncated proteins. |
Novel Insight: mRNA processing involves the removal of introns and the addition of a 5′ cap and a 3′ poly-A tail to the pre-mRNA molecule, which helps to stabilize the mRNA and facilitate its translation.
Risk Factors: Mutations in the promoter region, start codon, stop codon, splicing, tRNA charging, or ribosome function can all lead to errors in gene expression and protein synthesis.
How does transcription contribute to gene expression and protein synthesis?
| Step | Action | Novel Insight | Risk Factors |
|---|---|---|---|
| 1 | RNA polymerase enzyme binds to the promoter region of a gene | RNA polymerase enzyme is responsible for catalyzing the formation of RNA from DNA | Mutations in the promoter region can affect the binding of RNA polymerase and lead to decreased gene expression |
| 2 | Initiation complex formation occurs, which includes RNA polymerase, transcription factors, and other proteins | Transcription factors are proteins that help regulate gene expression by binding to specific DNA sequences | Mutations in transcription factor genes can lead to abnormal gene expression and contribute to the development of diseases |
| 3 | Elongation phase begins, where RNA polymerase moves along the DNA template strand and synthesizes a complementary RNA strand | RNA processing occurs during elongation, where introns are removed and exons are spliced together to form a mature mRNA molecule | Errors in RNA processing can lead to abnormal mRNA molecules and affect protein synthesis |
| 4 | Mature mRNA is exported from the nucleus and binds to ribosomes in the cytoplasm | Ribosomes are responsible for translating mRNA into a polypeptide chain | Mutations in ribosomal genes can lead to abnormal protein synthesis and contribute to the development of diseases |
| 5 | Initiation of translation occurs, where the ribosome recognizes the start codon on the mRNA and begins to assemble the polypeptide chain | Peptide bond formation occurs during translation, where amino acids are linked together to form the polypeptide chain | Errors in translation can lead to abnormal protein structures and affect protein function |
| 6 | Polypeptide chain elongation continues until a stop codon is reached, signaling the termination of translation | Post-translational modifications occur after translation, where the polypeptide chain is modified to form a functional protein | Errors in post-translational modifications can lead to abnormal protein function and contribute to the development of diseases |
How do peptide bonds contribute to the formation of polypeptides during protein synthesis?
| Step | Action | Novel Insight | Risk Factors |
|---|---|---|---|
| 1 | The process of protein synthesis begins with the assembly of a protein chain using the polypeptide synthesis pathway. | The polypeptide synthesis pathway is a step-by-step process that involves the formation of peptide bonds between amino acids. | The risk of errors in the assembly of the protein chain can lead to the formation of non-functional proteins. |
| 2 | During the chemical bonding reaction type known as condensation, the carboxyl group of one amino acid reacts with the amino group of another amino acid, forming a peptide bond. | The formation of peptide bonds is facilitated by the ribosome‘s catalysis function, which helps to align the amino acids and promote the formation of the peptide bond. | The risk of errors in the formation of peptide bonds can lead to the formation of non-functional proteins. |
| 3 | As the protein chain grows, the peptidyl transferase enzyme activity of the ribosome catalyzes the transfer of the growing polypeptide chain from the tRNA in the A site to the tRNA in the P site. | The peptidyl transferase enzyme activity of the ribosome is responsible for the elongation of the polypeptide chain during translation. | The risk of errors in the peptidyl transferase enzyme activity can lead to the formation of non-functional proteins. |
| 4 | The translation initiation step involves the recognition of the mRNA codon by the tRNA anticodon pairing process. | The mRNA codon recognition system ensures that the correct amino acid is added to the growing polypeptide chain. | The risk of errors in the mRNA codon recognition system can lead to the formation of non-functional proteins. |
| 5 | As the polypeptide chain grows, the amide group of the incoming amino acid reacts with the nitrogen-carbon covalent bond created by the previous peptide bond, forming a new peptide bond. | The formation of new peptide bonds during protein synthesis contributes to the elongation of the polypeptide chain. | The risk of errors in the formation of new peptide bonds can lead to the formation of non-functional proteins. |
| 6 | The process of protein synthesis continues until a stop codon is reached, at which point the C-terminal amino acid is added to the polypeptide chain. | The addition of the C-terminal amino acid completes the polypeptide chain and prepares it for protein folding and structure. | The risk of errors in the addition of the C-terminal amino acid can lead to the formation of non-functional proteins. |

Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| Consuming excessive amounts of protein will lead to more muscle growth. | The body can only utilize a certain amount of protein for muscle growth, and excess protein intake may be stored as fat or excreted by the body. It is important to consume an adequate amount of protein based on individual needs and goals. |
| All types of proteins are equal in terms of their ability to promote muscle growth. | Different types of proteins have varying amino acid profiles, which affect their effectiveness in promoting muscle growth. For example, whey protein has been shown to be particularly effective due to its high concentration of essential amino acids. |
| Protein supplements are necessary for building muscle mass. | While protein supplements can be convenient and helpful in meeting daily protein requirements, they are not necessary for building muscle mass if one’s diet already includes sufficient amounts of high-quality sources such as lean meats, eggs, dairy products, legumes, nuts and seeds etc.. |
| Eating more than the recommended daily allowance (RDA) for protein is harmful to health. | There is no evidence that consuming higher levels of dietary protein within reasonable limits causes any harm in healthy individuals with normal kidney function; however it should always be consumed according to individual needs and goals under guidance from a healthcare professional or registered dietician/nutritionist. |
| Consuming large amounts of animal-based proteins increases risk factors associated with heart disease. | Studies suggest that replacing some animal-based proteins with plant-based alternatives like beans or lentils may reduce the risk factors associated with heart disease while still providing enough nutrients required by our bodies including essential amino acids needed for building muscles. |
