medical educationresearchreviewsThis article emphasizes the importance of getting students to understand the ways in which polypeptides fold to form protein molecules with complex higher-ordered structures. Modern views on how this folding occurs in vitro and in the cell are summarized and set within ...
How do peptide bonds, polypeptides, and polypeptide chains relate to amino acids? How does an amino acid become attached to a tRNA molecule? What mechanism ensures amino acids get attached to the correct tRNA? Explain the need for varied amino acids in the protein we consume. ...
As bacteriocins are polypeptides and proteins, temperature control is crucial to ensure their activity during production and use.Streptococcus oralis subsp. dentisani7746 (AB-Dentisanium®), for instance, is optimally concentrated at 30 and 45 °C, with a small reduction in bacteriocin activity ...
Assembly:RNA and viral enzymes gather at the edge of the cell. An enzyme called protease cuts the polypeptides into viral proteins. Budding:New HIV particles pinch out from the cell membrane and break away with a piece of the cell membrane surrounding them. This is how enveloped viruses leave...

For example, oligopeptides contain anywhere between two and 20 amino acids, while polypeptides contain over 20. Peptides are naturally produced in the body and found in animals and plants. However, peptides in skincare are typically synthetic and made in labs. What are the benefits of peptides...
An enzyme called protease cuts the polypeptides into viral proteins. Budding: New HIV particles pinch out from the cell membrane and break away with a piece of the cell membrane surrounding them. This is how enveloped viruses leave the cell. In this way, the host cell is not destroyed. The...
Given that there are 20 amino acids, potentially there could be 20100 different amino acid sequences (an impossibly large number), just for polypeptides only 100 amino A DNA base pair sequence 192 bases in length would code for how many amino acids...
We model these unstructured polypeptides as extensible worm-like chains (eWLC) and employ polymer physics to obtain their force-induced extension \({d}_{{{\rm{p}}},{{{\rm{i}}}\left(f\right)\,\)(i = MHC and TCR) from their force-free, folded state, which has zero length34 ...
In eukaryotic cells, can many ribosomes make polypeptides from a single RNA? How did RNA and DNA end up together in living things? How do the proteins of the transcription machinery access DNA that is tightly associated in chromatin? How is RNA converted into cDNA? How can DNA be transcribe...
