Structure of DNA :Deoxyribonucleic acid: Molecular Biology: biochemistry

Molecular Biology: Part 2: DNA Structure. In this video, I have explained the structural organization of DNA. Deoxyribonucleic acid is polymers of deoxyribonucleotides attached to each other by phosphodiester linkages. Each deoxyribonucleotide is composed of deoxyribonucleoside & inorganic phosphate. Each deoxyribonucleoside is composed of nitrogen bases and sugar deoxyribose. The nitrogenous bases are purines and pyrimidines. The two purine bases are adenine and guanine. The two pyrimidine bases in DNA are cytosine and thymine. The deoxyribonucleotides are linked together by phosphodiester bonds between the 3' hydroxyl of the sugar of one nucleotide through a phosphate molecule to the 5' hydroxyl of another sugar nucleotide. The sugar and phosphate linkages form the backbone of the DNA to which the variable bases are attached. The sequence of the DNA is always written in the 5’ to 3’ direction. The genome of a cell consists of all its genetic information, encoded in deoxyribonucleic acid. In eukaryotes or DNA. DNA is located mainly in nuclei, but small amounts are also found in mitochondria. Deoxyribonucleic acids or DNA is packaged in chromosomes along with proteins in tightly coiled structures. https://vijayamarakala.com/category/biochemistry/organ-function-tests/liver-function-tests/ Liver function tests: /playlist/PLITxL6KOIm-b2dZapxDPFjs0FKzyo6PTk Diabetes and Insulin: /playlist/PLITxL6KOIm-bBPqs-xnLVnMCO3nID1Rz7 Hemoglobin metabolism: /playlist/PLITxL6KOIm-YOZksTDXgmplYR5GMNxon8 Molecular biology: /playlist/PLITxL6KOIm-a8IZFoGVd5voIn8zRYOvVv Electron transport chain: /playlist/PLITxL6KOIm-YNoCqQtPjZ5Cjm3tEi0YnW Enzymes: /playlist/PLITxL6KOIm-ZMFFdL1Haf2fpaazQuM1eD Digestion and absorption: /playlist/PLITxL6KOIm-ZzciIcbCyHt3wHZbiuDuO1 Carbohydrate chemistry: /playlist/PLITxL6KOIm-ZNbReHKD-S3kpjKAWHXIqG Lipid chemistry: /playlist/PLITxL6KOIm-aO94EbZQSqKTbO1YGeyX2S Protein chemistry: /playlist/PLITxL6KOIm-baCv9fkrnOm_32suZN2UCT Lipid metabolism: /playlist/PLITxL6KOIm-YKYpZS679cCAIKnKQX9-vS Acid-base disorders: /playlist/PLITxL6KOIm-YlQWecLaP0YQRu7Q_H_m96 ABG interpretation: /playlist/PLITxL6KOIm-ZBCRGYTj5bb0QGQ1aK4fRp Bilirubin metabolism: /playlist/PLITxL6KOIm-ZClrGdcDSkpCakLwoHwSrF Vitamins: /playlist/PLITxL6KOIm-Yh6oM0TL9xYk5rFdvGTEbS Bone and cartilage: /watch/xF69yYqriXM2KoWVM8L1wZ-mIOK6LxTILP=tsil&MruW38UNOtpN9 Carbohydrate metabolism: /playlist/PLITxL6KOIm-aWswjKFANjFUOwTpGm_INo Iodine and thyroid hormones: /playlist/PLITxL6KOIm-ZnfrllfWhw5ImiSlko3DVR Acid-base balance: /playlist/PLITxL6KOIm-Zc5kBLwUylhl9-fSoCzF6h Inborn errors of protein metabolism: /playlist/PLITxL6KOIm-aV_wvoJbLQWqdDp5TSoWLS Ketone body metabolism: /playlist/PLITxL6KOIm-ZzQroxjwykI4mGMUlwf1VK Vitamin D: /playlist/PLITxL6KOIm-aED2-s-bl8TmNV_9QAlV0u You can reach me through the following social media links Twitter: https://twitter.com/MarakalaVijaya Linkedin: https://www.linkedin.com/in/vijaya-ma ...
