Explain how electrophoresis can be used as a part of genetic testing.

Electrophoresis separates polypeptide chains and DNA chains by their fragment sizes after they have been cut by restriction enzymes are specific sites. Genetic testing involves checking genetic disorders by evaluating DNA sequences or protein amino acid sequences. By using restriction enzymes to cut DNA or polypeptides at specific sites, then run them on an electrophoresis, bands will form that will help indicate whether one has an abnormal sequence at the target site. If so, further analysis is used to determine the sequence by use of next-generation sequencing machines

During genetic testing, a segement of amplified DNA obtained from gene is digested using a restriction enzyme. Electrophoresis allows one to analyze the patterns by separating DNA by size. The process allows separation of different sizes of DNA fragments and provides genetic information in a wide range of data fields. A good example is genetic testing; Human DNA can be analyzed to provide evidence in criminal cases, to diagnose genetic diseases, and to solve partenity cases.

Answer:

Explanation:

All Cnidarians have appendages with stinging cells in their tips which are utilized to capture and stifle prey. In truth, the phylum title "Cnidarian" actually implies "stinging animal." The stinging cells are called cnidocytes and contain a structure called a nematocyst. The nematocyst could be a coiled thread-like stinger.

B) Frost

Frost is a thin layer of ice on a solid surface, which forms from water vapor in an above freezing atmosphere coming in contact with a solid surface whose temperature is below freezing, and resulting in a phase change from water vapor to ice as the water vapor reaches the freezing point.

What is plant "blinking"? Why do plants do this?

Likurg_2 [28]

BLINK protein speeds up stomatal movements in response to light fluctuations resulting in improved plant growth and water use.

Plants can't move, so their “blinking” helps protect them from burning or bleaching when they are in bright sun.

I'm not sure if the first part is right, but I do know the second part is.

A parent cell gives rise to daughter cells with identical genetic information. Which of the following data supports the idea tha

Yuri [45]

Answer:

A feline skeletal muscle cell undergoes cell division, resulting in two feline skeletal muscle cells.

Explanation:

We are looking for a parent cell that gives rise to daughter cells with identical genetic information.

In simpler words, we are looking for something that makes 'clones' of itself.

In this statement (second option), the parent and daughters are all feline skeletal muscle cells.

A feline skeletal muscle cell undergoes cell division, resulting in two feline skeletal muscle cells.

Other incorrect choices: (All having to do with reproduction).

A child has brown eyes; one of its biological parents has green eyes, and the other has brown eyes.

This situation has two parents, each with a different trait. The child takes one of the parent's trait. The parents did not make a 'clone' of themselves.

A human sperm fuses with a human egg cell, resulting in the development of a new human.

The parents don't make 'clones' of themselves. The sperm did not make more sperm. The egg did not make more egg cells.

A long-stemmed plant reproduces with a short-stemmed plant, and the offspring are all long-stemmed.

The offspring plant only took the trait from one of it's parents. Also, whole plants are not individual cells.
