Unit 1 - DNA and the Genome 0.0 / 5 ? BiologyDNA and the GenomeScottish HighersSQA Created by: NVLM_1999Created on: 27-04-17 17:01 What are nucleotides composed of? A phosphate, deoxyribose sugar and 1 of 4 nitrogenous bases. 1 of 10 What are the 4 nitrogenous bases? Adenine (A), Thymine (T), Cytosine (C) and Guanine (G). 2 of 10 What are the base pair rules? A pairs with T and C pairs with G. 3 of 10 What does the bond between the phosphate and deoxyribose sugar form? Sugar-Phosphate backbone. 4 of 10 What form does the DNA take? Double helix. 5 of 10 What are Prokaryotes? Organisms that lacks a true membrane bond nucleus. 6 of 10 Where is the DNA found in a prokaryote? In the cytoplasm. 7 of 10 What are Eukaryotes? Organisms that have a membrane bound nucleus that stores their genetic material. 8 of 10 How is the DNA in a Prokaryotes found? In a large circular chromosome and small plasmids. 9 of 10 How is the DNA in Eukaryotes found? In linear chromosomes (nucleus) and circular chromosomes (mitochondria (animals) and chloroplasts (plants)) 10 of 10
