Document Summary
Crucial molecule because carries genetic material, information passed from parent to offspring is required to produce organism. We are going to focus on 3: template for producing proteins (mrna, forms ribosomes (rrna) and catalyzing protein synthesis (along with proteins, carries amino acids to growing polypeptide chain during protein synthesis (trna) Deoxyribonucleotides contain deoxyribose, which is like ribose except c2" bears 2 h atoms instead of one h and one hydroxyl. Adenine adenosine a (don"t worry about memorizing structure) bigger ones with 2 ring system. Ring systems are generally flat and hydrophobic. Join to c1" of ribose or deoxyribose via n9 position. T dna only methly ch3 group. U rna only h. identical to t except u lacks ch3 group. Cytosine (c) in both dna and rna. Join to c1" of ribose or deoxyribose via n1 position. Ribonucleotides composed of 3 parts: a sugar, nitrogenous base, and phosphate: sugar ribose basis of ribonucleic acid, ribose always beta.
