Textbook Question
Chapter 12, Problem 13PDQ
Assume that a viral DNA molecule is a 50-μm-long circular strand with a uniform 20-Å diameter. If this molecule is contained in a viral head that is a 0.08-μm-diameter sphere, will the DNA molecule fit into the viral head, assuming complete flexibility of the molecule? Justify your answer mathematically.

Given the following eukaryotic DNA strand, transcribe and translate the DNA into a polypeptide using the 3’ – 5’ strand as the template. You may use drawings, diagrams, colours and annotations to describe how the DNA strand will be synthesized into a functional protein. (KEY: The letters SBMD are “made up” nucleic acids that depict non-coding regions in the DNA, hypothetically S pairs with B and M pairs with D).2.2. Describe what are missense mutations and its effects on structure and function using haemoglobin as an example
A biological motor used to package double-stranded (ds) DNA into viral capsids is able toexert 50 pN of force.
A. If the active site has a surface area of 10^-17 m2 , to what pressure can the biological motor package dsDNA within the viral capsid before stalling?
B.If the viral capsid has a radius of 30 nm, how much potential energy is stored due to the pressure-confinement of the dsDNA within the capsid?
C. Compare this to thermal energy at room temperature, kBT, where kB=1.38*10^-23 J/K is the Boltzmann constant.
Given the fact that 1 fg of DNA = 9.78 * 105base pairs (on average), you can convert the amount of DNA per cell to the lengthof DNA in numbers of base pairs. (a) Calculate the number of basepairs of DNA in the haploid yeast genome. Express your answer inmillions of base pairs (Mb), a standard unit for expressing genomesize. Show your work. (b) How many base pairs per minute weresynthesized during the S phase of these yeast cells?
