A DNA template strand contains the following sequence:
Nikitich [7]

Answer: Though the answer were not given, the complementary RNA strand is 5'UCCGAGGUC3'

Explanation: RNA is a single stranded nucleic acid produced from DNA. Four bases are usually found in DNA and they include adenine, Uracil, cytosine and guanine whereas adenine, thymine, cytosine and guanine are found in DNA. In RNA base pairing, wherever adenine is found in the DNA template strand, uracil occurs in the RNA strand, wherever thymine is found in the DNA template strand, adenine occurs in the RNA strand and anywhere cytosine occurs in the DNA template strand, guanine occurs in the RNA strand. This means that adenine pairs with uracil, cytosine pairs with guanine and thymine pairs with adenine.

Which stage of the human immunodeficiency virus (HIV) would a client with a CD4 T cell count of 325 cells/mm3 be classified
kirza4 [7]

Based on the CDC guidelines a person with a CD4+ cell count between 200-400 is regarded as being in <u>the second stage</u> of the HIV infection.

Acquired Immunodeficiency Syndrome

Acquired immunodeficiency syndrome (AIDS) is a condition caused by HIV (human immunodeficiency virus). AIDS is a chronic disorder and can become life-threatening for the infected person. The HIV viruses reproduce inside the host and while doing so they destroy the CD4+ immune cells which reduce the person's ability to fight against other diseases.

CD4+ cell count and AIDS

According to the CDC (U.S. Centers for Disease Control and Prevention), HIV infection is categorized into different stages based on the number of CD4+ cells.

  • Stage 1: - CD4+ cell count is more than 500 per microlitre. There are no symptoms or AIDS-related conditions.
  • Stage 2: - CD4+ cell count is more than 500 per microlitre. There are no symptoms or AIDS-related conditions.
  • Stage 3: - The CD4+ cell count falls below 200 and AIDS-related symptoms and conditions are present.
