Answer: Pelvic and sternum
Explanation:
bone marrow biopsy is a procedure that is used to obtain bone marrow usually with syringe for evaluation of various blood cells( leucocytes, erythrocytes ) and also for examination for different blood disesases such as leukemias and lymphomas and diagnose some genetic conditions. The common site for a bone marrow biopsy is the large pelvic bone near the hip and also some samples taken from the sternum (breastbone).
A bone marrow examination or test consists of two separate tests that are done at the same time namely:
1. Bone marrow aspiration that helps collect sample of the liquid portion of the bone marrow
2. Bone marrow biopsy that obtains a sample of the solid material.
Flowers and fruits are used by angiosperms to reproduce, while gymnosperms have unenclosed or "Naked" seeds on the surface of leaves or as cones
1. The correct answer is: The viral envelope proteins interact with CD4 and a co-receptor on the cell membrane.
Binding and entering the host cell are the first steps of the HIV virus infection. So, these steps play a major role in determining the ability of HIV to degrade the human immune system. Binding of HIV to CD4+ T lymphocytes (express chemokine receptors CCR5 and CXCR4 called co-receptors) triggers the fusion of the viral and host cell membranes, initiating infection (viral core gets into the cytoplasm).
Attachment of the virion can be:
• Nonspecific-envelop protein of the virus (Env) binds to cell-surface heparan sulfate proteoglycans
• Specific-Env binds to integrin.
2. The correct answer is: Activation of the host cell by cytokines, growth factors, or antigens.
After the viral capsid enters the cell, single-stranded RNA genome is released from the attached viral proteins and copied it into a complementary DNA (cDNA) molecule thanks to an enzyme called reverse transcriptase. Next step is the integration of the viral DNA into the host cell's genome. This process is done by another viral enzyme called integrase. The integrated DNA is transcribed into RNA and then translated into proteins that will help the package of new viruse particles.
3. The answer is: false
Reverse transcriptase is an enzyme that catalyzes the formation of DNA from an RNA template. Since the genome of the virus (HIV) is single stranded RNA, reverse transcriptase copies it into a complementary DNA (cDNA) molecule. Thanks to this enzyme, formed cDNA can be integrated into host’s genome. Because of this proprety, antiretroviral drugs used to treat HIV infection work as reverse-transcriptase inhibitors.
