Which elements are found in nucleic acids?, C, H, O, N, C, H, O, N, P, C, H, O, H, O, N, What are the components of a nucleotide?, Amino acid, sugar, phosphate, Nitrogenous base, sugar, phosphate, Lipid, sugar, phosphate, Base, lipid, enzyme, Which sugar is found in RNA?, Deoxyribose, Glucose, Ribose, Fructose, Which nitrogenous base is found in DNA but not RNA?, Adenine, Cytosine, Thymine, Uracil, What is the structure of DNA?, Single strand, Double helix, Circular, Branched, What is the structure of RNA?, Double helix, Single strand, Triple helix, Circular, What is the main function of DNA?, Energy production, Store genetic information, Transport nutrients, Break down food, RNA plays a role in, Digestion, Respiration, Protein synthesis, Excretion, Which base pairing is correct in DNA?, A–U, C–G, A–T, C–G, A–G, T–C, A–C, G–T, Which base replaces thymine in RNA?, Adenine, Cytosine, Guanine, Uracil, DNA wraps around which protein to form nucleosomes?, Enzyme, Keratin, Histone, Collagen, What is formed when DNA wraps around histone proteins?, Ribosome, Nucleosome, Mitochondria, Enzyme, Chromatin condenses to form:, Ribosome, Cytoplasm, Chromosome, Enzyme, Which statement explains the importance of DNA?, Produces energy, Stores and transmits genetic information, Breaks down food, Removes waste, Which sequence shows the correct formation of chromosome?, DNA → Chromosome → Histone, DNA → Histone → Chromosome, DNA → Nucleosome → Chromatin → Chromosome, DNA → Ribosome → Chromosome, A mutation occurs in a DNA segment that prevents transcription from taking place. What is the most likely effect on the cell?, DNA replication increases, mRNA is not formed, so protein cannot be produced, Ribosomes stop functioning immediately, More proteins are produced, A toxin blocks the function of ribosomes in a cell. What is the most likely effect?, DNA cannot replicate, mRNA cannot be formed, Proteins cannot be synthesised, Histone proteins cannot bind DNA.
