Reverse transcriptase

In the last few decades, many diseases have spread across all the nations. A numerous amount of these diseases are extremely life threatening. Of these diseases there is one which progressively affects millions of people. HIV is a deadly disease that has changed the world by taking millions of lives. Because HIV is a sexually transmitted disease, raising awareness, as introducing new methods for a safer sex is as vital as finding a cure. “HIV (Human Immunodeficiency Virus) is a lentivirus…

Justin bleeds so easily because he has a blood coagulation disorder that is brought on by blood clotting which is called Hemophilia A or Hemophilia B depending on which factor is deficient within his body (VIII or IX). In Justin’s case we are not presented with enough information to diagnose his type of hemophilia. However, a deficiency of either one of these factors can lead to problems with blood clotting that can cause severe bruising and bleeding even with minor trauma. It is possible that…

Saibhuvaneswari RA1611014010048 JUMPING GENES Transposable elements (TEs), also known as "jumping genes" or transposons, are sequences of DNA that move (or jump) from one location in the genome to another. A transposable element (TE or transposon) is a DNA sequence that can change its position within a genome, sometimes creating or reversing mutations and altering the cell's genetic identity and genome size. Transposition often results in duplication of the TE. The transposable elements make…

by a French geneticist, Jerome Lejeune as a hereditary congenital syndrome (1). Today, it is known as one of most frequent autosomal deletion syndromes that results from loss of the distal portion of chromosome 5 affecting the telomerase reverse transcriptase (TERT) gene (6). The deletion occurs at random during meiosis or early fetal development and varies in level of severity dependent upon the size of the deletion on the p arm. The deletion causes a structural abnormality that influences…

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…

The war against HIV …. The presence of HIV was tracked back to 1920 in Africa. There have been numerous attempts to stop HIV contraction through precautionary measures and detection and prevent progression once HIV has infected. The development of an effective process to fight the infection is crucial to sustain the disease and prevent spread, especially in poor and populated countries. But what if infection of HIV could be obstructed all together? Recent studies have explored the effect of…

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…

understanding is that the body’s immune system initiates an antibody response of IgM and IgG antibodies against the virus. Thus, serological or blood test and ELISA is use to diagnose the disease. These tests look for the presence of immunoglobulins. Reverse transcriptase PCR is use in labs for diagnosis because the virus is an alpha virus, single strand RNA (WHO, 2015). Once infected, the virus first travels via the blood stream and lymph and multiplies in the lymph nodes, liver, spleen and…

These treatments are categorized as well. The first category is called Non-nucleoside reverse tripticase inhibitors or (NNRTI). This specific drug works by disabling the protein HIV viruses need to make copies of itself. Without this protein the HIV virus replication process is slowed but not halted. Specific drugs that carry out this process…

In this world, there are many different kinds of diseases and viruses that can disperse easily and causes human all kinds unbearable sufferings such as the chickenpox, flu, and the cold. But the bright side to these diseases and viruses are that they are curable. But compared to a virus that is not curable is a different account. The virus named HIV (human immunodeficiency virus) is a disease that has no remedy. According to an article named, “Where did HIV come from?” by the AIDS INSTITUTE,…
