RNA virus

1) The major difference between these two is that the RNA viruses have RNA in their genome while the DNA viruses have DNA in their genome. Both the DNA and RNA cannot be found in the same virus. RNA virus first adsorbs to the host cell surface. Then the attached virus fuses with the endosome membrane. Unlike RNA viruses, DNA viruses pass their DNA into the nucleus of the host cell and not into the cytoplasm of the host cell. 2) Lysis: refers to the breaking down of the membrane of a cell, often by viral, enzyme, or osmotic mechanisms that compromise its integrity. A fluid containing the contents of lysed cells is called a lysate. Lysogenic: the biological process in which a bacterium is infected by a bacteriophage that integrates its DNA into that of the host such that the host is not destroyed. Virulence: the degree of…

The fifth chapter of Interplay centers itself around the principle of language, and how it so greatly effects interpersonal communication. One of the concepts that stuck out to me from this chapter was the nature of language, and how language is rule-governed. There are both phonological rules and syntactical rules, which respectively mean “how sounds are combined to form words” and “the way symbols can be arranged,” which are simply how the language is organized and interpreted to their…

2015, a widespread pandemic of the Zika virus (ZIKV) was reported in South and Central America and the Caribbean’s as well. The principal concern associated with this viral infection is the increased incidences of microcephaly in fetuses born to mothers infected with ZIKV. As a result, World Health Organization has declared it a pandemic that is affecting many lives. This paper will examine what the virus is in detail, by looking at its signs and symptoms, and second it will look at its…

silencing event, one strand of the silencing RNA needs to be discarded? By RNAi process, the double stranded RNA can induce silencing based on base pairing principles. The binding between the siRNA and miRNA with the mRNA will inhibit the gene expression. By this kind of gene silencing, some gene couldn’t be translating or activating. Which can be used to gene therapy some disease, such as cancer. But just the siRNA which full complementary binding with mRNA will lead to the cleavage of mRNA.…

Detection of Zika virus Introduction: Zika Virus, also referred to as ZIKV, has become a global health epidemic. The World Health Organization declared a Public Health Emergency of International Concern earlier this year due to the increase of areas affected by Zika. Originating in the Zika forest of Uganda, ZIKV was predominantly found in areas of Africa and Asia. However, there have recently been reports of more than 36 countries with cases of the virus. (Chen, 1), (CDC) ZIKV is a single…

caused by a bi-segmented negative RNA virus that is one of several viruses known to cause viral hemorrhagic fever. The Lujo virus is part of the Arenaviridae family, which consist of several viruses categorized into two groups. The Lujo virus is categorized in the “Old World” group, which signifies that the virus in question was found in the Eastern Hemisphere, specifically the continent of Africa. The majority of the arenaviruses categorized in the “Old World” group do not cause severe illness,…

Virus Taxonomy Order: Unassigned Family: Bunyaviridae Genus: Phlebovirus Species: Toscana virus talk.ictvonline.org Structure and genome The toscana virus (TOSV) is a negative-single stranded RNA virus, it is spherical in shape, it has an enveloped surrounding its capsid, and it has a diameter of 80–120 nm. Its genome is partitioned into three segments, termed (large)L, (medium)M and (small)S. With L about 6,400 nucleotides in length, M about 4,200 nucleotides in…

case of Zika virus infection reported? (10 pts) In 1947 Zika virus was first isolated from a monkey coming from the Zika forest in Uganda1. In 1952 first human infections were reported in Uganda and the United Republic of Tanzania1. Reference [1] The History of Zika Virus." World Health Organization. World Health Organization, n.d. Web. 02 Dec. 2016. 2. What are the common symptoms of Zika virus infection (Zika virus disease)? (10 pts) When a person is infected with Zika virus, he or she could…

hazards as minor as the common flu and as disastrous as the AIDS epidemic. Viruses have many types; one is an RNA virus. RNA virus is a virus that has RNA as its genetic material. One of the human diseases that is caused by RNA virus is the Ebola virus. In order for someone to be infected by Ebola, one must come into contact with the virus. It can enter the human body through the nose, mouth or breaks in the skin. Once inside, it finds a host cell to infect. The viral enzymes take the enzymes of…

In order to prevent a virus we must first learn its history; how it came about and where, we must then take into perspective how it is spread and then take preventative measures to ensure that the minimal amount of people are infected. A virus is simply defined as a non-living, infectious agent that must use a host cell in order to replicate. What makes these viruses so dangerous is that they’re numerous, and thus easy to spread and catch. This is not to say that every virus affects us, some…
