MCQ’s GENERAL PATHOLOGY- CELL CYCLE (29/03/21) 1.Correctly matched with organ and stem cell niche are all except? A) Intestine- crypts B) Eyes- limbus of cornea C) Brain- periventricular zones D) Bone marrow- Paratrabecular area Answer: D- Bone marrow stem cell niche is – peri-sinisoidal region. 2. Which is the true statement A) Rb gene is the key regulator of G2M cell cycle transition. B) Rb is active in hypophospholylated state C) MDM2 protein activates p53 D) p53 activation leads to cell cycle progression Answer: B – is true, Rb is the regulator of G1/S phase, MDM2 protein inhibits p53 and p53 active leads to transient cell cycle arrest.

MCQ’S GENERAL PATHOLOGY-GROWTH FACTORS AND RECEPTORS (28/3/20) 1.All are true about receptors with tyrosine kinase activity except? A) Downstream phosphorylation is a common pathway of signal transduction B) Changes in receptor geometry can stimulate intrinsic receptor protein kinase activity C) The cellular homologue of the transforming protein of the Rous sarcoma virus, called Src, is theprototype of this family. Answer: C – src is a prototype of non- receptor tyrosine kinase family 2. Which one is matched correctly? A) EGFR- synonymous to ERB-B2 B) Her-2-neu -ERB-B1 C) TGF-beta- Inflammatory cytokine D) Hepatocyte growth factor- Scatter factor. Answer- D – erb-b1 is EGFR, erb-b2 is her2-! and TGF-beta is anti-inflammatory 3. Which of the following is false about collagen ? A) Collagen I,V and XI are heterotrimers B) Defects in collagen occur in marfan syndrome C) Helix formation occurs in the golgi apparatus D) Cross-linking occurs in the extracellular space Answer: B- Marfan syndrome is caused by defects in fibrillin For more questions checkout Questions and explanations on cellular housekeeping: https://pathologymcqforall.wordpress.com/2021/03/28/general-pathology-mcqs-topic-cellular-house-keeping/ Questions and explanations on genome: https://pathologymcqforall.wordpress.com/2021/03/26/mcqs-general-pathology-genome-26-03-2021/ CLICK HERE FOR ROBBINS PATHOLOGY CHAPTERWISE MCQs You may join telegram channel- Pathology mcqs For pathology mcqs, quizzes, interesting facts and updates – Visit HOME – Pathology for all Join the Facebook page for daily questions- Pathology mcq Share this:FacebookTelegramWhatsAppMoreLinkedInTwitterLike this:Like Loading...
GENERAL PATHOLOGY MCQS- TOPIC: CELLULAR HOUSE KEEPING Q1. Which of the following is not matched correctly? A) Lysosome- Autophagy B) Endosomal vescicles- shuttle internalized materials outside the cell C) Proteosome- Degrades tagged proteins D) Peroxisomes- Breaks down very long chain fatty acids. Answer: B- Endosomal vesicles- shuttle internalized materials to other organelles inside the cell 2. Identify the cytoskeletal protein shown in the image Clues: Most abundant and 5-9 nm in diameter A) Actin B) Myosin C) Desmin D) Laminin Answer: A – Actin microfilaments are 5- to 9-nm diameter fibrils formedfrom the globular protein actin (G-actin), the most abundant cytosolic protein in cells. G-actin monomers noncovalently polymerize into long filaments (F-actin) that intertwine to form double stranded helices with a defined polarity 3. All are true regarding protein synthesis except? A) Membrane bound ribosomes in the RER translate mRNA. B) Chaperones assist folding of proteins. C) From the RER, proteins and lipids destined for other organelles or extracellular export are shuttled into the Golgi apparatus D) O- linked oligosaccharides are converted into N- linked Oligosaccharides in golgi apparatus. Answer: D – N-linked oligosaccharides are pruned and extended in a stepwise fashion into O-linked oligosaccharides in the golgi . Some of this glycosylation is important in sorting moleculesto lysosomes (via the mannose-6-phosphate receptor); other glycosylation adducts are important for cell-cell or cell-matrix interactions or for clearing senescent cells (e.g., platelets and erythrocytes).
