What allows us to perform the Biochips?

Biology
1 answer:
andre [41]1 year ago
3 0

Answer:In addition to genetic applications, the biochip is being used in toxicological, protein, and biochemical research. Biochips can also be used to rapidly detect chemical agents used in biological warfare so that defensive measures can be taken. Hopefully this helps

Explanation:A biochip is a collection of miniaturized test sites (microarrays) arranged on a solid substrate that permits many tests to be performed at the same time in order to achieve higher throughput and speed. Typically, a biochip's surface area is no larger than a fingernail. Like a computer chip that can perform millions of mathematical operations in one second, a biochip can perform thousands of biological reactions, such as decoding genes, in a few seconds.A genetic biochip is designed to "freeze" into place the structures of many short strands of DNA (deoxyribonucleic acid), the basic chemical instruction that determines the characteristics of an organism. Effectively, it is used as a kind of "test tube" for real chemical samples. A specially designed microscope can determine where the sample hybridized with DNA strands in the biochip. Biochips helped to dramatically accelerate the identification of the estimated 80,000 genes in human DNA, an ongoing world-wide research collaboration known as the Human Genome Project. The microchip is described as a sort of "word search" function that can quickly sequence DNA.In addition to genetic applications,

why do polysaccharides like cellulose and peptidoglycan able to resist degradation and enzymatic activity
mixer [17]

Polysaccharides like Cellulose form insoluble micro-fibrils making it resistant to degradation and enzymatic activity.

<u>EXPLANATION: </u>

  • Polysaccharides components in general broken down monosaccharides and they are very little enough to be absorbed by the body.
  • But the polysaccharide like cellulose cannot be absorbed by our body.
  • Cellulose is made up of simple polymers that form insoluble micro-fibrils results in resistant to degradation and enzymatic activity.
  • Also, molecules of each micro-fibril are so tightly packed structure and prevent the penetration of enzymes.
  • Thus, cellulose degradation requires a complex enzyme and cellulose.

Contact lens solution is described as a sterile, buffered, isotonic aqueous solution. Explain the importance of the adjectives b
OLEGan [10]

A contact lens is a lens placed on the cornea of the eye.


Importance of buffers in contact lens products:

Buffers: They aim to keep the pH of the solutions at values ​​between 6.6 and 7.8 in order to maintain the lens parameters and the effectiveness of the solutions. They are made by the combination of an acid and its sodium salt (phosphate and acetate for example). Borate and citrate buffers are used.


Importance of isotonicity in contact lens products:

The solution composed by isotonic saline solution.

Isotonia is expressed by osmolarity or cryoscopic lowering

- 0.236 to 0.446 mOsmoles / l (increases during the day)

- If the osmolarity of the mixture is different from that of the tears, it causes discomfort and irritation

• Increased tear secretion

• Increase the blink frequency

- If hypotonia, entry of water to the epithelial cells, if hypertonia: inverse

- Osmolarity restored 1 or 2 minutes after instillation

What modifies and transports proteins?
Alexandra [31]

<u>Answer:</u> The Golgi apparatus is found close to the nucleus of the cell, where it modifies proteins that have been delivered in transport vesicles from the RER. It is also involved in the transport of lipids around the cell. Pieces of the Golgi membrane pinch off to form vesicles that transport molecules around the cell.

A bacterium is infected with an experimentally constructed bacteriophage
dem82 [27]

The complete question is:

a bacterium is infected with an experimentally constructed bacteriophage composed of the T2 phage protein coat and T4 phage DNA. The new phages produced would have

A) T2 protein and T4 DNA

B) T2 protein and T2 DNA

C) a mixture of DNA and proteins of both phages.

D) T4 protein and T4 DNA

E) T4 protein and T2 DNA

A bacterium infected with an experimentally constructed bacteriophage will give new phages with the virus' DNA and the type of proteins that this DNA encodes.

A bacteriophage is a virus that attaches itself to a bacteria and uses it to replicate itself. Viruses have two main parts, a protein coat and their DNA inside it.

  • The experimentally constructed bacteriophage has one type of protein that makes the coat, the T2. This type of protein will allow the virus to attach and infect the bacteria.
  • Once the virus attaches itself to the bacteria, it will introduce its DNA, T4 type, and use the bacteria elements to replicate it and create new phages.
  • As a result, the new phages will have T4 DNA, and the proteins that the virus synthesizes will be the same type as the DNA.

In conclusion, The new phages produced would have D) T4 protein and T4 DNA.
