A. What the size of the human genome? B. what is the range of genome sizes for mammals? C. What is the size of the Escherichia coli genome? D. What is the range of genome sizes for Bacteria? E. Are some viral genomes larger than some Bacteria genomes? Estimate how much larger are the largest animal genomes compared to the smallest virus genomes? (10-fold? 100-fold? How many fold?) Figure 7.3. Distribution of genomes sizes (from Lesk, page 239) Mammals Animals Plants uses 10100 T 01 10 10 When you answer in Blackboard using exponents, any of the following three conventions works for me: e.g., 100-10. or 10"2 or 10e2Explanation / Answer
A. Size of human genome is 3,000 Mb ( megabase pairs ) or 3.0×10^9 bp.
B. Range of genome size of mammals is 10^8 to 10^9 bp.
C. Size of E. Coli genome is 5.44×10^6 bp.
D. Range of genome size for bacteria is approximately 10^6 to 10^7 bp.
E. Yes, some viral genome is larger than bacteria genome.
F. Largest animal have genome size 10^11 bp and smallest virus have 10^3 bp. So difference is of 10^11 -10^3 = 10^8 or 800 fold of bp.
