Dideoxynucleotides are chain-elongating inhibitors of DNA polymerase, used in the Sanger method for DNA sequencing. They are also known as 2',3' dideoxynucleotides, and abbreviated as ddNTPs (ddGTP, ddATP, ddTTP and ddCTP).

Dideoxynucleotides are useful in the sequencing of DNA in combination with electrophoresis. The purpose of the deoxynucleotide triphosphates (dNTPs) is to supply the “bricks.” Since the idea behind PCR is to synthesize a virtually unlimited amount of a specific stretch of double-stranded DNA, the individual DNA bases must be supplied to the polymerase enzyme.

A client has thin, dark-red vertical lines about 1 to 3 mm long in the nails. Which diseases are associated with this physiologi
qaws [65]

Answer:

- Trichinosis

- Bacterial endocarditis

Explanation:

Trichinosis is a parasitic infection that has as its etiological agent the nematode parasites of the genus Trichinella, and the species of greatest interest to human medicine is Trichinella spiralis.  One of the first and characteristic symptoms of infection is the swelling of the eyelids, which appears around the 11th day after infection. Subsequently hemorrhages appear in the eye sclera and in the back of the eyes, eye pain and photosensitivity. Then there is the appearance of muscle pain, along with a rash and bleeding below the nails causing dark red vertical lines about 1 to 3 mm long. The pain is intense in the muscles linked to breathing, chewing and swallowing.

Bacterial endocarditis is always associated with a bacteremia that the immune system has failed to counteract. In other words, the presence of bacteria in the bloodstream, which is usually sterile, represents an important cause of bacterial endocarditis, an infection that affects the inner membrane lining the heart and heart valves, especially if they already have a disorder. The disease sets in when bacteria from various parts of the body - from the mouth mainly, but also from the skin, intestines, respiratory tract, and urinary tract - are carried through the bloodstream to a heart valve or other damaged endocardial area where fix it. Among the many symptoms, indicative of the presence of this disease in the body are thin dark red vertical lines about 1 to 3 mm long in the nails.

How does the sea ice in 2019 compare to the sea ice in 2012 during April?
Katarina [22]

The total amount of sea ice showed a decline from 2012 to 2019. The correct option would be D.

<h3>Graphical illustration</h3>

Looking at the graph, from February to June 2012, there is a decline in the amount of sea ice.

A similar decline in the amount of sea ice can be observed in the year 2019.

However, the sea ice levels for the various months in 2012 remain generally above the sea ice levels in the various months in 2019.

Thus, overall, one can say there is a general decline in the ice level from 2012 to 2019.
