Briefly describe why herpes simplex viruses (HSVS) cause chronic lytic infections that typically recur at the same location, sometimes years after being dormant.

During a lytic cycle, viral DNA replication occurs without phage production or the death of the cell while during the lysogenic cycle many copies of the phage are produced within the bacterial cell, the bacterium breaks open. Select one: True False

Answer the two questions below by reading the article 1, What was discovered in this article and how is it interesting 2, How is this discovery in the article related to genetics Article The novel SARS-CoV-2 coronavirus that emerged in the city of Wuhan, China, last year and has since caused a large scale COVID-19 epidemic and spread to more than 70 other countries is the product of natural evolution, according to findings published today in the journal Nature Medicine. The analysis of public genome sequence data from SARS-CoV-2 and related viruses found no evidence that the virus was made in a laboratory or otherwise engineered. "By comparing the available genome sequence data for known coronavirus strains, we can firmly determine that SARS-CoV-2 originated through natural processes," said Kristian Andersen, PhD, an associate professor of immunology and microbiology at Scripps Research and corresponding author on the paper. In addition to Andersen, authors on the paper, "The proximal…

Select all the following events that occurs in both the lytic and lysogenic cycle of bacteriophage T4 infection.   viral protein synthesis    digestion of host DNA    attachment    entry

"Although the reported number of cases varies, arboviruses cause substantial morbidity in the United States each year. Cases occur sporadically, with epidemiology varying by virus and geography. Weather, zoonotic host, vector abundance, and human behavior all influence when and where arboviral outbreaks occur, making it difficult to predict locations and timing of cases and underscoring the importance of surveillance in identifying outbreaks and informing prevention efforts." Which of the following means the same as "Cases occur sporadically"? O Cases are caused by fungal spores. O Because of vector transmission, there is a steady rate of arboviral cases each year O Outbreaks occur unpredictably QUESTION 8 "Although the reported number of cases varies, arboviruses cause substantial morbidity in the United States each year. Cases occur sporadically, with epidemiology varying by virus and geography. Weather, zoonotic host, vector abundance, and human behavior all influence when and where…

Name two common diseases caused by herpesviruses.

Which of the following is NOT true about the current coronavirus global pandemic (COVID-19)? Laboratory diagnosis of infection is based on polymerase chain reaction (PCR) testing of patient samples for RNA from the causative virus Nucleic acid vaccines to prevent COVID-19 (and/or its most severe forms) are authorized for use in the US Caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Person-to-person transmission can occur through respiratory secretions (droplets and/or aerosols) None of the other four answers (All are true about COVID-19

Cytomegalovirus (CMV) infection Hi, can you please elaborate about Cytomegalovirus (CMV) infection (e.g. genomics, clinical test, signs-symptoms-treatment, transmition and prevention, possible complications if it is acquired, etc.)

Compare and contrast the role and types of viral mutations in 1918 IAV and SARS-C0V-2 in the respective pandemics, paying particular attention to: 1. causes of mutations 2. Key mutations responsible for generating highly pathogenic viral strain. 3. effects of mutated viral gene products on host immune system. 4. effects of newly emergent viral strain on virus spread worldwide.
