False True Telomeres contain crucial protein-coding genes in eukaryotes. Telomeres help maintain the integrity of chromosomes in both eukaryotes and bacteria. Telomeres are protected by forming T loops combined with a shelterin protein complex. Linear chromosomes tend to become progressively shorter with each replication cycle. DNA polymerases cannot synthesize new DNA at the tips of single-stranded 5' ends.

4. (a) Classically, the probability (per unit length) of finding a particle in a box of length L is a constant 1/L along the entire length of the box (assuming that we can't just open the box and look inside). Determine the classical expectation value for the position of the particle ($\bar{x}$), the expectation value for the square of the position ($\langle x^2 \rangle$), and the uncertainty in position ($\Delta x$). (b) Quantum mechanically, the probability (per unit length) of finding a particle in an infinite potential well is given by $|\Psi(x, t)|^2$. Determine the uncertainty in position for a particle in the nth stationary state of the infinite potential well. Under what circumstances does this result agree with the classical uncertainty from (a)? (c) Determine the uncertainty in momentum for a particle in the nth stationary state of the infinite potential well. Does this state satisfy the Heisenberg uncertainty principle?

Analyze Linear Programming Practice Problems Name 3. A seafood restaurant owner orders at least 50 fish. He cannot use more than 30 amberjack or more than 35 flounder. Asian carp costs $4 each and flounder costs $3 each. How many of each fish should he use to minimize his cost? 4. Jermaine makes two types of wood clocks to sell at local stores. It takes him 2 hours to assemble a pine clock, which requires 1 oz of varnish. It takes 2 hours to assemble an oak clock, which takes 4 oz. of varnish. Jermaine has 16 oz. of varnish in stock, and can work 20 hours. If he makes $3 profit on each pine clock and $4 on each oak clock, how many of each type should he make to maximize his profits?
