A researcher wants to compare how much myosin protein is present in samples of fish muscle tissue. All muscle tissue contains myosin. Muscle tissue from three types of fish, salmon, catfish, and trout, are prepared and loaded into separate wells on a polyacrylamide gel. Electrophoresis is conducted and the gel is stained with Coomassic blue. Which statements below are truc (select all that apply). a. Only one single blue band corresponding to mysoin protein will be present in each lane. b. Each lane will contain multiple blue bands representing the array of proteins present in fish muscle tissue. No bands will be visible unless the proteins are transferred to a blot, probed with antibody specific for myosin, and subjected to colorimetric detection. d. Multiple protein bands will be visible after the proteins are transferred to a blot, probed with myosin antibody, and subjected to colorimetric detection.

Answers

Answer 1

Based on the information provided, the correct statements are Each lane will contain multiple blue bands representing the array of proteins present in fish muscle tissue and Multiple protein bands will be visible after the proteins are transferred to a blot, probed with myosin antibody, and subjected to colorimetric detection.


a. This statement is incorrect because the polyacrylamide gel electrophoresis (PAGE) separates all proteins in the sample, not just myosin. Therefore, each lane will contain multiple bands representing various proteins in the muscle tissue.

b. This statement is correct because PAGE separates proteins based on their size and charge, leading to multiple blue bands in each lane. Coomassie blue stains all proteins, so it will display an array of proteins present in fish muscle tissue.

c. This statement is incorrect because although Western blotting is a technique used to detect specific proteins (like myosin), the question states that the gel is stained with Coomassie blue, which stains all proteins.

d. This statement is correct because if the proteins are transferred to a blot and probed with an antibody specific for myosin, only the myosin bands will be detected through colorimetric detection. This method is called Western blotting and is used to detect and analyze specific proteins within a sample.

What are the causes of Air pollution?

The causes of air pollution include excessive burning of fossil fuels, industrial emissions, carbon emissions from automobiles, construction and industrial wastes, etc.

Acid deposition may be also known as Acid rain. It includes the form of precipitation with several acidic components like nitric acid and sulfuric acid.

These precipitations finally falls on the earth from the atmosphere in the form of rain, snow, fog, etc., and are deposited on tall trees, buildings, and objects, and lose their natural beauty.

how would you make an extract of a food to test for reducing sugar​

Answers

To test for the presence of reducing sugars, a food sample is dissolved in boiling water. Next, a small amount of Benedict's reagent is added and the solution begins to cool. During the next four to 10 minutes, the solution should begin to change colors. If the color changes to blue, then no glucose is present. If a high amount of glucose is present, then the color change will progress to green, yellow, orange, red and then a dark red or brown.

In a herd of beef cattle, the average yearling weight of all animals was 800 lb when corrected to a bull basis. Bulls and heifers kept for breeding weighed 1000 and 825 lb, respectively. The progeny of those individuals selected for breeding had an average yearling weight corrected to a bull basis of 845 lb. What is the apparent genetic control of the trait

Answers

Answer:

Explanation:

The trait is genetic and not dependent on environment. When a trait is dependent on the genetic component of the parental generation, the ability of the traits to be passed from a generation to another is high and this will be revealed in their resemblance with the parent. Hence, the case of the offspring with an average weight of 845lb.

If the trait is controlled or influence by the environment there will be a difference when the offspring is produce because until the same environment is given to the offspring the trait cannot be expressed.
