O Secondary Primary Quaternary Tertiarywhen a protein has achieved the _______ level of protein structure, it takes on a 3d shape due to the r group interactions. primary secondary tertiary quaternary
- Quaternary structure of the protein is possible for Both monomeric and multimeric protein Multimeric protein Monomeric protein All protein structuresIf provided with a DNA sequence, you should be able to identify where transcription will start; which regions are introns; where the start and stop of translation will occur; as well as what the amino acid sequence of the encoded protein will be. Determining the tertiary structure of a protein is much more challenging however, requiring laborious techniques such as X-ray crystallography or cryo-electron microscopy. Advances in AI protein structure prediction methods such as Alpha Fold2, now make it much easier to visualise protein structures based on the amino acid sequence. Consider the protein structures shown below for NLR protein A and B. Assess the quality of the AlphaFold predictions, by comparing it to the protein structures as determined by Cryo-electron microscopy.Which of the following factors do not stabilize the 3-D structure of a folded protein? O Disulfide bonds O Van der Waals interactions O Hydrogen bonds O Electrostatic interactions O Hydrophobic bonds Metal-ion protein interactions
