1. Protein synthesis requires energy in the form of ATP and GTP. Two high-energy phosphate bonds (from ATP) fuel the formation of one aminoacyl tRNA. Formation of the initiation complex requires energy from one GTP. Delivery of each new tRNA to the Asite requires one GTP. Termination requires the hydrolysis of one GTP.   Based on this information, the table of codons, and your understanding of the processes of Activation, Initiation, Elongation, and Termination, answer the following questions.

a. How many high energy phosphate bonds are required for the translation of a 100 amino acid polypeptide, starting with mRNA, tRNA, amino acid and all the necessary enzymes

b. A portion of prokaryotic mRNA has the following base pair sequence: 5’ACAUCUA(U)GCCACGA3’. What would happen if the base in the brackets was mutated to an A.

Please solve both parts and explain in detail !! Thank you

The Human Eye THE HUMAN EYE: While digital camera form images with pixels, the human eye forms images with rods and cones that lie on the retina. If two point objects close together are to be seen as two distinct objects, the images must fall on the retina on two different cones that are not adjacent. That is, there must be a cone between them. Assume that the cones are sensitive to a wavelength of 550nm. If the iris is about 5mm in diameter, and we can model the human eye as a sphere with roughly a 25mm diameter,

a. What is the minimum separation between two objects at a distance of 2rn away from the eye that we can resolve at this wavelength?

b. What is the distance between the two cones on the retina?

Discuss the search and matching models.

a) Shortly discuss the phenomenon of search frictions and the implications they may have for the labour market outcomes.

b) What does the Beveridge curve measure?

This question is about human capital accumulation in terms of on-the-job training.

C) Define general and firm specific human capital.

D) Discuss who pays for investments in human capital that leads to general human capital and to firm specific human capital.

If you treat intact chromatin (30 nm fiber) with heparin, to remove H1, followed by extensive treatment with a single restriction enzyme, what sort of banding pattern would you expect to see on a gel following de-proteinization and electrophoresis?

Serine proteases......
A) use an Asp, Lys, Ser catalytic triad
B) use a Shiff base-enzyme intermediate
C) cleave the Cα-carbonyl C bond

D) all of the above
E) B and C

F) none of the above

The sequence of an estrogen-responsive element is given below.

What would you be the most likely consequence of the introduction of this sequence of about 200 bases upstream (-200) of the gene transcirption initiation site encoding the enzyme mucosa?

It appears that over the past 50 years, the number of farms in the United States declined while the average size of farms increased. The following data provided by the U.S. Department of Agriculture show five-year interval data for U.S. farms. Use these data to develop the equation of a regression line to predict the average size of a farm (y) by the number of farms (x). Discuss the slope and y-intercept of the model.

(Do not round the intermediate values. Round your answers to 2 decimal places.)
