What change occurs in the bone to make conformational abnormalities permanent? ( regarding foals)

Expert Solution

Ans . The following changes in bone of Foals can make conformational abnormalities permanent :-

(i) Club foot :- It is a term that describes a hoof with a foot axis of 60 degrees or more. This condition can be acquired or congenital (present at birth). This condition occurs almost exclusively in the forelegs.If the clubfoot is congenital, it results from a congenital flexural deformity contracture of deep digital flexor tendon. An acquired clubfoot often is the result of an injury or condition that causes pain in leg , resulting in disuse.The leg than develops a flexural deformity from the disuse, and the hoof changes shape as a result. An acquired clubfoot also can be result of nutritional problems, leading to same flexural deformity.

(ii) Toed-in (Pigeon Toed) :- This flaw is recognized when viewing the horse from the front. One or both hooves will point inward. The deviation can begin at the shoulder or hip, or as low as the fetlock.This conformational abnormality- like many of the others is congenital in nature. Toed-in conformation leads to aberrations of the leg during flight ; the leg will travel in an outward arc (paddling) during movement.

(iii) Carpus valgus ( lateral deviation of the Carpus ; Knock knees) :- This is one of the angular limb deformities that occurs in foals. These congenital deformities are common. The carpal valgus occurs when one or both carpi(knees) deviate outward when viewed from front.

Upon binding of epinephrine to β-adrenergic receptor, a conformational change is propagated from its extracellular face to its intracellular face leading to release of the G⍺ subunit and subsequent binding of GTP and activation of downstream components of the pathway. What prevents G⍺ from indefinitely activating the fight-or-flight response? Cleavage of G⍺ subunits by Thrombin. ATIII. Intrinsic GTPase activity. GAPs GEFs Which components of GPCR signaling pathways are transmembrane proteins? GPCR G-protein Effector protein (ex: adenylyl cyclase) PKA

A rod-shaped DNA molecule (rod) of length 250 nm undergoes a conformational change to a closed-circular (cc) form. (a) Assuming that scattering light has a wavelength of 488 nm, calculate the ratio of scattering intensities of each of these conformations (i.e. Irod/Icc) when q = 20°, 45°, and 90°. Use the following values: M = 4 x 106 g/mol ns = 0.556 cm3/g Rg = 117.0 nm (b) Based upon this answer, what is the best value of q to...

Osteosarcoma is a relatively rare type of bone cancer. It occurs most often in young adults, age 10 - 19; it is diagnosed in approximately 8 per 1,000,000 individuals per year in that age group. In New York City (including all five boroughs), the number of young adults in this age range is approximately 1,400,000. a) What is the expected number of cases of osteosarcoma in NYC in a given year? b) What is the probability that 15 or more...

.What are protein conformational changes and describe FIVE examples of their involvement in any aspect of signal transduction. One of the examples MUST be the involvement of kinases. Describe the stages of the cell cycle and what happens in each stage, making sure to include what is happening to the DNA. For M phase, describe all stages. If you were looking at cells under the microscope, what would you use as a distinguishing feature for each stage.
