Read the scenario. Jake and Pari are completing a biology assignment. One of the questions asks them to determine the base amoun
postnew [5]

Answer:

There should be 10% thymine

Explanation:

DNA bases come in specific pairs. Guanine pairs up with cytosine and adenine pairs up with Thymine.

According to the problem the DNA sample was 40% cytosine and 40% guanine, so this is correct, there are equal amounts of cytosine and guanine. Now Thymine needs to have equal amounts as adenine, but adenine only has 10%.

If we match up the amount of adenine to thymine, we would have 15% adenine and 15% thymine, but that would excede 100%. So you need to match the thymine to adenine.

10% adenine + 10 % thymine + 40% cytosine + 40% guanine = 100%

Your patient has recently completed her first round of chemotherapy in the treatment of lung cancer. when reviewing this morning
dimaraw [331]

When there is myelosuppression, the suggestive finding is there is a decrease in the platelets and red blood cells. Also called the bone marrow suppression, myelosuppression is a common side effect of the treatment of chemotherapy. When this side effect happens, there is a decrease in the production of blood cells. The result which may be the effect of myelosuppression is a decrease in one, two or all three types of blood cells. Most patients of chemotherapy experience a decrease in red blood cells. Another effect is the decrease of white blood cells by most patients. Myelosuppression will be subcategorized as neutropenia when chemotherapy results to the reduction of neutrophils which is a specific type of white blood cells. Thrombocytopenia is the term for a drop in platelet numbers. This kind of suppression is not that common.  Only 10 percent of cancer patients undergo the negative effects of this kind of suppression.
