A — is a protein that recognizes and responds to a signal

Biology
1 answer:
Norma-Jean [14]3 years ago
3 0

Answer:

A <u><em>receptor</em></u> is a protein that recognizes and responds to a signal.

Explanation:

A receptor is a protein molecule present on the cells on which the signalling molecules can bind and generate a physiological response. Some receptor molecules can also respond to Sun and light. Each type of cell has specific receptors molecules and hence can respond to specific signals. The receptor molecules hence tend to receive signals for a cell. Molecules such as hormones bind to the receptors.

6. (3 pts) After transformation, 40 colonies were present on the plate. What is the transformation efficiency of the competent c
natali 33 [55]

Answer:

Given:

Number of colonies on plate = 40

Amount of DNA used for transformation = 100ng

Volume of competent cells used = 100ul

Total volume = 1ml (1000ul)

Volume plated for growth = 200ul

The amount of cells transformed per 1 µg of DNA is called the transformation efficiency

(CFU is colony forming units) => (number of colonies on plate/ng of DNA plated) X 1000 ng/µg = CFU/µg of DNA

Amount of DNA used for plating = 100ng * (200/1000)

                                                      = 100ng * (1/5)

                                                      = 100/5 = 20ng

Efficiency calculation = 40 colonies / 20ng = 2 colonies/ng

               (2 colonies/ng) * (1000 ng/µg) = 2000 CFU/ug DNA

Transformation efficiency = 2000 Transformants / ug DNA

                                          = 2 x 10³ Transformants / ug DNA

Explanation:

Efficiency of transformation is highest in the 100 pg-1 ng range, so Low transformation efficiency could be because of high amount of DNA used for transformation.

A patient's HDL, LDL, and triglyceride levels are 62, 77, and 60, respectively. What is the patient's total cholesterol score? S
Len [333]

Answer:

Total cholesterol score is 199

199 is high cholesterol score especially as it very close to 200. The patient should adopt diets that do not include high cholesterol food

Explanation:

a. Firstly, we want to calculate the patient’s total cholesterol score.

To get this, we use a mathematical approach.

Mathematically;

the total cholesterol score = HDL + TDL + Triglyceride = 62 + 77 + 60 = 199

The patient’s total cholesterol score is 199

b. As a doctor, I will advice the patient on the status of these measurements. Using the scale of cholesterol level, a measurement of total cholesterol = 200 represents a high cholesterol level. Since 199 is very close to 200, the patient is at a risk of high cholesterol levels and thus needs a dietary change.
