A technique in molecular genetics permitting the analysis of any short sequence of DNA or RNA is Polymerase Chain Reaction (PCR).

<h3>What do you mean by Polymerase Chain Reaction (PCR)?</h3>

A method used during molecular genetics to make a number of copies of a specific DNA region are called a polymerase chain reaction. A given DNA segment can be amplified into a number of copies using the polymerase chain reaction, allowing for more in-depth analysis. In PCR, a section of the genome to be amplified is chosen using shorter synthesized Fragments of DNA called primers. Multiple sets of DNA polymerase are then utilized to amplify that segment.

telo118 [61]

Answer:

c. lobes  

Explanation:

Brain lobes are divisions of the cerebral hemispheres, designated by the names of the surrounding cranial bones and covering them. The frontal lobe is located in the forehead region; the occipital lobe in the nape region; the parietal lobe in the upper central part of the head; and the temporal lobes in the lateral regions of the head above the ears.

Parietal, temporal and occipital lobes are involved in producing the perceptions resulting from what our sensory organs detect in the outer environment and the information they provide about the position and relationship to outer objects of different parts of our body.

Do pandas blink? If so why or why not?
In-s [12.5K]
Pandas only blink sometimes because they are looking out for danger most of the time. Like other mammals, they have an upper and lower eyelid, so yes they do blink, but not as much as humans.

A graph with a calibration curve, linear regression and extrapolation was drawn up from your lab results. What were the two type
fiasKO [112]

Answer:

X is the concentration of the substance being measured and Y is the response from the instrument that is being used to measure

Explanation:

A calibration curve is the plot of known concentration of substances where x is the increasing known concentration and Y is the response, typically "absorption" taken from the instrument that is used for measuring. This curve is then used to find out the concentration of the unknown substance by using it's absorbance and comparing it with the calibration curve. For example:

Concentrations and absorbance readings are as follows

0.5mg/mL=10 nm

1.0mg/mL=15nm

1.5mg/mL=20nm

2.0mg/mL=25nm

This data is plotted on a calibration curve. Next we measure the unknown substance the absorption is 20nm. We can suggest that the concentration is 1.5 mg/mL. If there are readings that fall inbetwen values then the formulat to calculate the right concentration would be y = mx + b, where m is the slope and b is the y-intercept.

Linear regression uses the modification of the slope formula y= a + bx to best see how the data of the water samples would fit on the slope of the calibration curve. X is the independent variable , b is the slope of the line and a is the y-intercept.

Extrapolation would be the action of calculating data that are outside the calibration curve,  assuming the trend would continue.
