An organism is found to have a single large chromosome of 2 x 109 base pairs. Its replication forks move at the rate of 50 base pairs per second.
In fact, S phase is completed in 300 minutes (5 hours). How many origins of replication must there be (minimally) on this large chromosome in order for it to replicate completely in S-phase? Show your math.

1. The genome of organism A consists of approximately 2.184 ×109 base pairs, and DNA synthesis occurs at a rate of 500 base pairs per second. How many minutes would it take to synthesize the entire genome of organism A, if there were only one origin of replication? 2. It turns out that organism A is actually able to synthesize its entire 2.184 ×109 bp genome in only 35 minutes. How many origins of replication must there be? 3. The...
Answer both a and b. The genome of the bacteria E. coli is 5.4 X 106 nucleotides long. Replication of the DNA here is 500 nucleotides/second. Replication is bi-directional from the single origin, so each fork copies ~ half of the DNA and the two forks probably get done at about the same time. a. How long should it take (in minutes) for replication to be completed in E. coli? The haploid human genome is 3 X 109 nucleotides long,...
For questions 1 and 2, please remember that there are two replication forks per origin, and that the synthesis of the two new daughter strands occurs at the same rate and at the same time. 1. (4 points) The pathogenic strain O157:H7 of E. coli has one circular chromosome. The DNA molecule in this chromosome contains 5,498,450 bp. DNA synthesis at one replication fork occurs at a rate of 70,000 nucleotides per minute. How many minutes will it take to...

Exercise 2 Separation of a Mixture Based on Acid-Base Properties One purpose of this exercise is to learn how to use a separatory funnel to extract a single component away from other compounds in solution. To do so, we will apply the principles of solubility and acid-base behavior you’re seeing in class. One of the compounds is neutral in the acid-base sense. It has no ability to either donate or accept a proton from an aqueous solution, and will remain...
1. What is the definition of an 'equivalence point' in an acid/base titration? (1 point) 2. In part one of the experiment, you will prepare the acid solutions being titrated from a stock solution. Describe how you will accurately prepare 10.00 mL of 0.100 M HCl solution using a 1.00 M HCl stock solution. In your response to this question, be very specific about the quantities of stock solution and deionized water to be used in the dilution and the...
LAB Genetic Engineering of Bacteria Problem Is it possible to transfer the allele for resistance to the antibiotic ampicillin into a bacterial cell? Objectives After completing this lab, the student will be able to: 1. Demonstrate micropipetting and sterile pipetting techniques for handling and transferring bacteria and plasmid DNA. 2. Maintain sterile conditions for culturing bacterial cells. 3. Inoculate bacteria into flasks, culture tubes, or agar plates. 4. Culture isolated individual colonies from an agar plate to form genetically identical...
En (2 points) You isolated your mitochondrial DNA in Part I. In step 6, you discard the supernatant, but keep the pellet. In step 15, you discard the pellet, but keep the supernatant. Explain why the pattern is different between the two steps and the consequence of mixing up these two steps. Procedure Part 1: mt DNA Isolation from your cheek cells. Lysis solution is used to breakdown the cells in this step, you will isolate MEONA from cheek cells....
