The only correct answer is: D phosphodiester A is incorrect as this bond is found in lipids B is incorrect as this bond is found in carbohydrates C is incorrect as this bond pair bonds nucleotides (1) Question Number Answer Additional Guidance Mark 1(b) A description that makes reference to the following points: • {DNA polymerase} {joins the sugar phos...

compound interest - 30 60 90 triangle 45 45 90 triangle - Solubitlity Rules - 1) group 1, NO3-, NH4+, ClO4-, C2H3O2- (acetate) soluble salt 2) Most Ag+, Pb2+, Hg2 (2+) salt insoluble (exept when paired with above). Plant Hormones (A CAGE) - Auxin / IAA (indoleacetic acid): plant growth, elongation, phototropism Cytokinin: stimulates cytokinesis Abscisic Acid (ABA): growth inhibitor. delay growth. Gibberellins: cell growth Ethylene: gas, ripen fruit and leaf abscission

are microorganisms the only organisms used in biotechnology? - ️️other organisms such as goats and cows are also used in biotechnology for example genetically modified goats produce spider silk in their milk and cows have been genetically modified to produce human antibodies describe the nature of the offspring produced by embryo splitting - ️️although the offspring will all be clones of one another the offspring which develop will depend on the egg and sperm that fuse during fertilis...

BOT 331 Exam 4 Questions With Solutions True/false, if false explain why A protein that binds ATP and transfers a phosphate onto a substrate is called a Protein Phosphatase. False, a Protein Phosphatase removes phosphates from its substrate; a Protein Kinase transfers phosphates onto its substrate. True/false, if false explain why Indole-3-acetic acid is chemically derived from a nitrogenous base. False, indole-3-acetic acid, also called auxin, is chemically derived from tryptophan, wh...
