Healthcare associated or nosocomial pneumonia are
acquired by non-hospitalized patients in hospitals or other health care
facilities. Pneumonia are poly-microbial in origin and the causative agents are
viruses, bacteria and fungi. In nosocomial pneumonia, bacteria enter the lower
respiratory tract due to mechanical ventilation. Meanwhile, persons in general
population experience community-acquired pneumonia.
The invention of PCR make DNA fingerprinting possible because "PCR made it possible to produce enough copies for reliable tests".
<u>Option: C</u>
<u>Explanation:</u>
With the development of the PCR technique, DNA profiling has made enormous progress both in its distinguishing capacity and in its ability to survive information from very limited or damaged beginning samples. The PCR cycle mimics the biochemical mechanism of DNA replication yet restricts it to fragments of concern unique to DNA.
In the PCR method, the specimen of DNA is denatured by heating into separate polynucleotide strands. Two primers of DNA oligonucleotides are used for hybridization on opposite DNA strands to two matching nearby sites. Thus two new copies of the interest sequences are produced. Quantitative PCR methods allow accurate, high and automated calculations of the throughput.
Answer:
Bacterial DNA is contained in one circular chromosome, located in the cytoplasm. Eukaryotes have several linear chromosomes. Bacteria also have two additional unique features: a cell wall and flagella. Some bacteria also have a capsule outside the cell wall
Answer:
b. format painter
Explanation:
Format painter is an option that is available on the home tab and it allows copying the formatting present in one to another single cell or a group of cells.
The formatting options can include font style, the color of the text, the border style.
To use the format painter some simple steps needs to be followed:
1. Click on the Format painter tab on the home tab.
2. Clicking on the format painter will help to copy the format of the selected cell.
3. The copied formatting can be applied to other cells of interest by clicking and dragging over the cells where a similar formatting is required.
4. The ESC buttton can be pressed to stop formatting .
