Molecular chaperones are proteins that assist in the proper folding, assembly, and stabilization of other proteins. They prevent misfolding and aggregation, guide proteins to their functional conformation, and can help refold or target damaged proteins for degradation. This is an MCQ on Protein Chaperones (MCQ on Molecular Chaperones). Molecular Biology […]
Caspases are a family of protease enzymes that play essential roles in apoptosis (programmed cell death) and inflammation. They cleave specific proteins at aspartic acid residues, triggering cellular processes such as DNA fragmentation and membrane blebbing during apoptosis. This is an MCQ on Caspases in Apoptosis (Structure and Functions of […]
The nucleus is a membrane-bound organelle in eukaryotic cells that contains most of the cell’s genetic material in the form of DNA. It serves as the control center, regulating gene expression and facilitating DNA replication and RNA transcription. This is an MCQ on Nucleus Structure and Functions. | Cell and […]
