A normal cell from the lung of an organism contains 52 chromosomes. What is the haploid

Biology
1 answer:
Naddik [55]3 years ago
5 0

Answer:

26

Explanation:

Lung cells are somatic cells, meaning that they are diploids (2n).

The number of chromosomes in a haploid (n) cell is half as much as the diploid cell.

In this case, 2n = 52

so: n = 1/2 × 2n = 1/2 × 52 = 26

List three conditions that would alter the activity of an enzyme. be specific with your explanation.
anyanavicka [17]
Three conditions (or inhibitors) will stop the enzyme's reaction from taking place. If another substance attaches to the site first the the reaction will not take place because the substrate can no longer attach to the active site. Conditions within the cell like temperature and acidity will also inhibit the reaction because it will change the shape of the active site which is very specific for the substrate that needs to attach to it. The enzyme will then become ineffective.

2. Do you believe that this patient is suffering from a genetic disorder? Why or why not?
zhenek [66]

Answer:A genetic disorder is a disease that is caused by a change, or mutation, in an individual's DNA sequence. A genetic disorder is an illness caused by changes in a person's DNA. ... Our DNA provides the code for making proteins?, the molecules that perform most of the functions in our body.

How are genetic conditions treated or managed?

Many genetic disorders result from gene changes that are present in essentially every cell in the body. As a result, these disorders often affect many body systems, and most cannot be cured. However, approaches may be available to treat or manage some of the associated signs and symptoms.

For a group of genetic conditions called inborn errors of metabolism, which result from genetic changes that disrupt the production of specific enzymes, treatments sometimes include dietary changes or replacement of the particular enzyme that is missing. Limiting certain substances in the diet can help prevent the buildup of potentially toxic substances that are normally broken down by the enzyme. In some cases, enzyme replacement therapy can help compensate for the enzyme shortage. These treatments are used to manage existing signs and symptoms and may help prevent future complications.

For other genetic conditions, treatment and management strategies are designed to improve particular signs and symptoms associated with the disorder. These approaches vary by disorder and are specific to an individual's health needs. For example, a genetic disorder associated with a heart defect might be treated with surgery to repair the defect or with a heart transplant. Conditions that are characterized by defective blood cell formation, such as sickle cell disease, can sometimes be treated with a bone marrow transplant. Bone marrow transplantation can allow the formation of normal blood cells and, if done early in life, may help prevent episodes of pain and other future complications.

Some genetic changes are associated with an increased risk of future health problems, such as certain forms of cancer. One well-known example is familial breast cancer related to mutations in the BRCA1 and BRCA2 genes. Management may include more frequent cancer screening or preventive (prophylactic) surgery to remove the tissues at highest risk of becoming cancerous.

Genetic disorders may cause such severe health problems that they are incompatible with life. In the most severe cases, these conditions may cause a miscarriage of an affected embryo or fetus. In other cases, affected infants may be stillborn or die shortly after birth. Although few treatments are available for these severe genetic conditions, health professionals can often provide supportive care, such as pain relief or mechanical breathing assistance, to the affected individual.

Most treatment strategies for genetic disorders do not alter the underlying genetic mutation; however, a few disorders have been treated with gene therapy. This experimental technique involves changing a person's genes to prevent or treat a disease. Gene therapy, along with many other treatment and management approaches for genetic conditions, are under study in clinical trials hope this elps u a lot
