Biology

ValentinkaMS [17]3 years ago
6 0

DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code. Human DNA has around 3 billion bases, and more than 99 percent of those bases are the same in all people. DNA sequencing theory is the broad body of work that attempts to lay analytical foundations for determining the order of specific nucleotides in a sequence of DNA

A nurse obtains a health history from a mother who son is taking methylphenidate. she reports that he is having hallucinations.
FromTheMoon [43]

Methylphenidate refers to a CNS stimulant mainly used in the treatment of ADHD (attention deficit hyperactivity disorder) in children between the age of 6 to 12, adults up to the age of 65, and adolescents. It can also be used in the treatment of narcolepsy.  

However, the application of the drug may also bring some side-effects with it. Some of the common side-effects related to medicine are decreased appetite, headache, hallucinations, sweating, fever, dizziness, increased heart rate, weight loss, and others.  

In the given case, due to the application of the drug, the child is having hallucinations. Thus, in the given case, the nurse should recommend the client to report the manifestations as quick as possible, and discontinue the use of medicine.

Differentiate between persistent and latent animal virus infections.
lana66690 [7]

Answer:

The difference between both infections is that viral infections where the virus is latent, this virus once infected is protected in the nerves of the animal organism, as for example in humans the herpes family viruses (HSV1) are housed in ganglionic terminals such as the trigeminal ganglion or the V cranial nerve, so that in a situation of immunodepression, reinfect the individual again, causing him to be unable to remove the virus from his body.

On the other hand, persistent infections diseases are the threats that persist because the microorganism cannot be eliminated, either because it is very complex, or the cure does not exist, or the correct treatment is not carried out. Furthermore, it is necessary to consider that some microorganisms mutate becoming resistant to these drugs and thus persist longer in the body until they are eliminated.

Explanation:

In short, latency refers to the fact that the individual lives with the virus for life, and persistence is that it is possible to eliminate it over a long period of time since the infectious microorganism is considered very difficult.

Identify how the addition of acetyl groups to histones leads to a weaker association of DNA in nucleosomes.
kipiarov [429]

The addition of acetyl groups to histones leads to a weaker association of DNA in nucleosomes because they help to condense it into chromatin.

<h3>What is the relationship between histones and DNA?</h3>

Histones are a family of basic proteins that associate with DNA in the nucleus and help to condense it into chromatin. Nuclear DNA does not appear on free linear strands; it is highly condensed and involves histones to fit inside the nucleus and participate in the formation of chromosomes.

<h3>How does DNA compact with histones?</h3>

Each chromosome is made up of a single molecule of double-stranded DNA wrapped around histones, the nucleosome. This fiber rewinds into a second level of compression, known as the solenoid. Most of the time, cells keep the DNA compacted in the selenoid loops attached to the chromosomal backbone.

Whit this information, we can conclude that the addition of acetyl groups to histones leads to a weaker association of DNA in nucleosomes because they help to condense it into chromatin.
