Central Dogma - correct answerDNA-(Transcription) - RNA- (Translation) -Protein DNA Structure - correct answer1. Deoxyribose: 5 Carbon atoms are numbered 1' to 5' . Hydrogen attached to 2'. Sugar 2. Phosphate group Sugar-Phosphate backbone is asymmetric because PO4 groups connect the C5' of a sugar with the C3' of neighbouring sugar. = Asymmetric ends because the C5' end is attached to a PO4 and the C3' end is simply a hydroxyl group of the sugar. 3. Nucleic Acid: No-covalently bon...
