The spectrum of p53 mutations is not a strong argument to infer neomorphic or antimorphic mutations Unlike most other tumour suppressor genes that are inactivated by frameshift or nonsense mutations leading to disappearance or aberrant synthesis of the gene product, almost 80% of p53 gene mutations are missense mutations leading to the synthesis of a stable protein, lacking its specific DNA-binding activity and accumulating in the nucleus of tumour cells (Soussi, 2005). Whether this hig...

How is cell division possible in eukaryotes versus prokaryotes? - Answer-*Eukaryotes* - Mitosis - > somatic cells - Meiosis -> gametes *Prokaryotes* - Binary fission What is the outcome of Mitosis/Cytokinesis? - Answer-A parent cell is divided to create two identical daughter cells to the parent and each other (clones) What are the three functions of Mitosis? - Answer-1) Growth 2) Repair/ Replacement 3) Asexual Reproduction What is a chromosome? - Answer-- A structure carrying ge...
