In python, how do you move the pointer of a doubly linked list to the last node? Also in python, how do you move the current pointer "n" elements ahead (circularly)

def go_last(self):
# moves 'current' pointer to the last node

def skip(self,n:int):
# moves 'current' pointer n elements ahead (circularly)

Please answer all parts.

A)

By binding in the A-site, tetracycline:

• A.

  Prevents the initiator tRNA from binding

• B.

  Prevents the exit of empty tRNAs

• C.

  Prevents the next charged tRNA from binding in the ribosome

B)

If an antibiotic that binds to the E site of the ribosome is added right before translation starts, which one of the statements is TRUE?

• A.

  The end product only has 1 amino acid.

• B.

  Translation would not be affected.

• C.

  The end product only has 2 amino acids.

C)

The diagram below depicts translation as the fourth amino acid is added to the polypeptide chain. In the growing polypeptide chain, which amino acid is colored?   

• A.

  Valine (Val)

• B.

  Methionine (Met)

• C.

  Isoleucine (Ile)

• D.

  Glutamine (Gln)

• E.

  Alanine (Ala)

D)

While the overall process and mechanism of translation is conserved across all living organisms, which of the following statements are true for both prokaryotes and eukaryotes?

• A.

  The 70S ribosomal complex is composed of a large 50S and a small 30S subunit.

• B.

  The 3’ end of the 16S rRNA in the small ribosome subunit recognizes the Shine-Dalgarno sequence on the 5’ end of mRNA.

• C.

  The translation initiation complex is complete when the start codon (AUG) is positioned in the P site and the initiator tRNA carrying fMet (N-formylmethionine) binds.

• D.

  Peptidyl transferase catalyzes the formation of a peptide bond between the amino acids in the P and A sites, and then the peptide chain moves to the tRNA at the A site.

• E.

  Aminoacyl-tRNA synthetases translocate the ribosome by exactly one codon, moving the tRNA with the peptide chain in the A site to the P site.

• F.

  Translation termination occurs when a release factor binds a stop codon (UAG, UGA, UAA) in the A site.

Suppose that each firm in a competitive industry has the following costs:

where qq is an individual firm's quantity produced.

The market demand curve for this product is

where PP is the price and QQ is the total quantity of the good.

Each firm's fixed cost is $_____

What is each firm's variable cost?

q

50+1/2 q

1/2q

1/2q^2

Which of the following represents the equation for each firm's average total cost?

50/q

50+1/2q

50/q+1/2q

1/2q

Complete the following table by computing the marginal cost and average total cost for qq from 5 to 15.

Answer just this past please

The average total cost is at its minimum when the quantity each firm produces (qq) equals _______

.

Which of the following represents the equation for each firm's supply curve in the short run?

q

50−q

1/2q^2

120−1/2q^2

In the long run, the firm will remain in the market and produce if _______.

Currently, there are 16 firms in the market.

In the short run, in which the number of firms is fixed, the equilibrium price is______

and the total quantity produced in the market is_____units. Each firm produces____

units. (Hint: Total supply in the market equals the number of firms times the quantity supplied by each firm.)

In this equilibrium, each firm makes a profit of $______

. (Note: Enter a negative number if the firm is incurring a loss.)

Firms have an incentive to _____ the market.

In the long run, with free entry and exit, the equilibrium price is _____

, and the total quantity produced in the market is_____units. There arefirms in the market, with each firm producing____

units.

The production function of a good is f(L,M)=4L1/2 M1/4, where L is the number of units of labor and M is the number of machines used. The cost of labor is $20 per unit and the cost of machines is $10 per unit. If the firm decides to produce Q units of output, (1) Does the production function exhibit increasing returns to scale? Why? (2) Get the conditional factor demand for L and M. (3) If there is a set-up cost at $1000. Find the total cost of producing Q units of output using the answer from (2). (4) Find the average total costs function and marginal costs function?

A new father plans on saving for his daughter’s college education. He will donate $775.00 on her first birthday. After that, he will increase his donation by 3.00% each year and will make his last contribution on her 18th birthday. If he can earn 9.00% each year in his investment account, how much will his daughter’s college fund be worth on her 18th birthday?

Facts: Butcher Block is an Austin (Travis County), Texas company that packages meat products for sale to local convenience stores. When its refrigerated delivery truck suffers an engine failure, Butcher’s president Billy contacted Vaught Motors, an Oklahoma City company that sells refrigerated vans and trucks to businesses. Billy negotiated with Vaught sales associate Annie a valid contract for the immediate sale and next-morning delivery of a used 2017 Mitsubishi Fuso FE 140 for $45,000 (including a time-of-the-essence clause because Butcher could make no deliveries without the truck). Vaught delivered a vehicle promptly, but it was a 2019 GMC G33705 van. Butcher rejected delivery because the GMC van—though newer, so the price was good—had only half of the storage capacity as the Mitsubishi truck and thus would not allow Butcher to make all of its deliveries each day. Butcher instead bought an equivalent Mitsubishi truck from another seller for $50,000. The day it was supposed to receive the truck from Vaught, Butcher missed all of its deliveries, which were worth $10,000 in profit. It also had to rent a delivery truck for 10 days at $500/day so that it could fill its orders while it awaited the truck from the alternate seller.

Question 1: Explain whether Vaught performed or breached its contract with Butcher and what the potential damages are for Butcher.

Question 2: For this second question only, assume that Annie was a probationary sales associate, and her manager Madelyn had told her orally not to do contracts above $25,000 without consulting her, and Annie did not consult Madelyn about the contract with Butcher. Billy had contacted Annie directly through the Vaught website, which told customers “Our sales associates can get you the right truck for your business,” and it included Annie’s name and contract information. Explain under agency law principles whether Vaught or Annie (or both) is liable for money damages if Butcher were to win a judgment for breach of contract.

Essay 3: If Butcher sues Vaught in a court located in its home (Travis County, Texas), explain what court or courts have subject matter jurisdiction over the lawsuit and whether there is personal jurisdiction over Vaught. Also address whether Butcher can sue in a court if the contract contains a clause requiring the parties to arbitrate.
