the disease and symptoms. Some of the medications may even help with stopping the spread of the HIV virus. The regimen of medications is tailored to the individual patient. There are several different categories of medications available. (NIH) Nucleoside Reverse Transcriptase Inhibitors (NRTIs) work by blocking reverse transcriptase, which is an enzyme that the HIV virus needs to make copies of itself. Some of the medications in this category are; Ziagen, Videx, Epivir, Zerit and Retrovir (AZT)…

Latin term meaning death. Upon death, respiration ceases to occur. Without oxygen, metabolism stops, organs shut down. The body’s main source of energy is the cell production of ATP. Wikipedia’s definition:” Adenosine triphosphate (ATP) is a nucleoside triphosphate used in cells as a coenzyme often called the "molecular unit of currency" of intracellular energy transfer. ATP transports chemical energy within cells for metabolism”. Muscles are packed with multinucleated striated cells that…

virus at different points of the cycle. Taking three different medications controls the virus better and protects the immune system. This process is called Antiretroviral Therapy (ART). Some examples of antiretroviral medications include Nucleoside/non-nucleoside reverse transcriptase inhibitors also called “nuke” that help block the most important step of HIV reproduction process. These two medicines block the enzyme reverse transcriptase and prevent the virus from making copies of its DNA.…

The Microbe Hepatitis B virus belongs to a group called, Hepadnaviridae which consists of diseases that contain deoxyribonucleic acid (DNA) and affect the liver. Hepatitis B is a virus therefore; hepatitis B requires a living host to replicate viral particles. Hepatitis B consists of a nucleic acid core, a protein coat, and a lipid envelope. The hepatitis B virus contains a partially double-stranded DNA within the nucleic acid core because one of the full-length strands is linked to the viral…

Biology Matching Terms DNA- is the replication of your parents and ancestors genes RNA- is the transcription of dna, ribonucleic acid; guides protein synthesis. Translation- process in which RNA is synthesized from the template DNA. Transcription- process in which RNA attaches to the ribosome and a protein is assembled. Replication- method of DNA replication in which parental strands separate, act as templates, and produce molecules of DNA with one parental DNA strand and one new DNA strand.…

The strongest difficulty with any naturalist explanation of life 's origins is showing how the primary building blocks were created. In RNA the building blocks are a nitrogenous base known as a nucleoside, and a sugar called ribose. When these molecules combine they form a nucleotide, and these nucleotides connect to form the chain-like structure of RNA. It is believed that ribose formed as a byproduct of a formose reaction in the prebiotic soup…

The growing HIV rates within MSM are so severe that studies have been conducted to explore the possible factors that are leading to the growing rates. A study conducted in Los Angeles that involved 797 MSM and MSM/W from the Sexual Acquisition and Transmission of HIV-Cooperative Agreement Program found that the reason people lack awareness “of HIV status may be due to stigma” (14). With the use of the Internalized Homonegativity index, researchers found that “anti-gay attitudes and perceptions…

One of the most recent ethical issues has been on the genome editing done by CRISPR and whether editing the genes will lead to a terrifying sci-fi moment. The panic being that one day parents will be allowed to edit their future child’s genome so that they may have the “perfect child”. Recognizing the fears of the people, we have to be aware that there will always be the fear of something going wrong or that the new technology will be abused. It is a common fear that we have with many of the…

According to a mathematical model, the drug is estimated to provide a 99% risk reduction in the contraction of HIV in high-risk individuals if taken 4 times a day . Both medications act as nucleoside analog reverse transcriptase inhibitors. They compete with the reverse transcriptase enzyme needed by the HIV virus to replicate, reducing the probability of an individual becoming HIV positive. Despite the estimated capacity of Truvada, the stigma…

Amino acids Amino acids are building block s of proteins. Each amino acid contains main three structural components. 1) Amino group 2) Carboxcilic group 3) R group Figure 1 https://www.bing.com/images/search?q=amino+acids&view=detailv2&&id=072990A13D7C6B29926E0FC3F9E9BE59C8A6322E 2016 R can be hydrogen or any other functional group .in world there are around 182-200 found to be present in nature but we can find 20 aminoacids in…
