Molecular Biology Quiz week 11

Protein Structure

• The primary structure of a protein refers to the sequence of amino acids connected by peptide bonds.
• Peptide bonds are responsible for connecting amino acids in a protein's primary structure.

Protein Structure Prediction

• Online resources such as Phyre2 and I-TASSER can be used for protein structure prediction.

Protein Quaternary Structure

• The quaternary structure of a protein refers to the arrangement of multiple polypeptide chains (subunits) in a protein.

Protein Secondary Structure

• The secondary structure of a protein is characterized by the arrangement of alpha helices and beta sheets.

Protein Synthesis

• tRNA (transfer RNA) plays a crucial role in protein synthesis by carrying amino acids to the ribosome during translation.

Cellular Transport

• Exocytosis is the cellular process that involves the release of substances from a cell through vesicles.

Peroxisomes

• The main function of peroxisomes in a cell is to break down fatty acids and amino acids.

Post-Translational Modification

• Ubiquitination is a post-translational modification that involves the addition of ubiquitin to proteins, marking them for degradation.

Autophagy

• The main function of autophagy in a cell is to recycle damaged organelles and proteins.

Membrane Transporters

• The primary location for the classification of membrane transporters is the Transporter Classification Database (TCDB).

Cellular Protein Visualization

• Immunofluorescence microscopy is a technique used for visualizing cellular proteins.

Organelle Interactome

• The organelle interactome refers to the network of interactions between different organelles in a cell, and its main function is to facilitate cellular communication and regulation.
