1. A student is observing a cell under the microscope. It is observed to have supercoiled DNA with histones. Which of the following would also be observed by the student? a. A single circular chromosome b. A nucleus c. Free-floating nuclear material d. No organelles ANS: B The cell described is a eukaryotic cell, so it has histones and a supercoiled DNA within its nucleus; thus, the nucleus should be observed. A single circular chromosome called a prokaryote contains free-floating nucle...

NBME Pathology verified 100% full solution Apoptosis: - ANSWER-Programmed cell death. REQUIRES ATP. Can occur via the intrinsic or extrinsic pathways, both of which involve activation of cytosolic caspases which mediate cellular breakdown. ***Unlike necrosis, apoptosis does not involve significant inflammation. Involves eosinophilic cytoplasm, cell shrinkage, pyknosis and basophilia, membrane blebbing and karyorrhexis, and formation of apoptotic bodies which are phagocytosed. **DNA ladderin...

Cytoplasm is a clear, thick gel containing carbohydrates, lipids, proteins and other chemicals that surrounds the nucleus in a cell. Homeostasis is the condition where internal and external environments remain constant and in balanceCe The Four Phases of Mitosis are? prophase, metaphase, anaphase, telophase Morphology is the description of the form and structure of tissues on the body Hypertrophy is an increase in the size of a tissue Atrophy is a decreas...

A - Alanine (1 letter) Activation of enzymes through ligand binding: why would this be useful? - The binding of a ligand to an allosteric site of a multimeric enzyme often induces positive cooperativity, that is the binding of one substrate induces a favorable conformation change and increases the enzyme's likelihood to bind to a second substrate. Ala - Alanine (3 letter) Arg - Arginine (3 letter) Asn - Asparagine (3 letter) Asp - Aspartic Acid (3 letter) Barr body and relation to hete...
