DNA fragment sizes, identify species or individuals, and assist in studies like population genetics or genetic modification. What are common troubleshooting steps if DNA bands are not visible after gel electrophoresis?
redity Understanding inheritance is crucial. MCQs may focus on: Mendelian principles: dominant, recessive traits, Punnett squares. Chromosomal basis of inheritance. Genetic mutations. Modern genetic concepts like DNA structure, replic
fats, oils, phospholipids, and steroids, primarily serving as energy reserves and structural components of cell membranes. Nucleic acids (DNA and RNA) store and transmit genetic information. Key points: Lipids are hydrophobic, with f
