b. Reference your source correctly (guide) using APA style. Use the Centers for Disease Control and Prevention (cdc.gov) as your source.
The CDC’s mission is to protect America from health, safety and security threats, both foreign and in the U.S. One current health threat is the coronavirus disease 2019 (COVID-19). A new coronavirus that had never been identified is a novel coronavirus. COVID-19 is a novel coronavirus.
Disease: Initially, the disease was referred to as 2019 novel coronavirus (2019-nCoV). The disease was formally named COVID-19 on Feb 11, 2020.
1. What organization is responsible for setting up rules for naming the disease?
2. What does the abbreviation COVID-19 represent?
Virus: On February 11, 2020, an organization was charged with naming the new virus. They named the novel coronavirus, SARS-CoV-2.
3. What organization is responsible for naming the virus?
4. What does the abbreviation SARS-CoV-2 represent?
Coronaviruses are a large family of viruses. Some cause illness in people (like the common cold) and others infect animals (such as canine and feline coronaviruses). Rarely, animal coronaviruses that infect animals emerged to infect people and spread between people. This is suspected to have occurred for the virus that causes COVID-19. Two other examples of coronaviruses that originated from animals and then spread to people are Middle East Respiratory Syndrome (MERS) in 2012 and Severe Acute Respiratory Syndrome (SARS) in 2003.
5. Briefly describe MERS and SARS and how they are similar to COVID-19?
As of today, there are a total of seven coronaviruses that are known to infect humans. Four human coronaviruses cause mild respiratory tract infections. These are OC43 , 229E, HKU1 and NL63. Three human coronaviruses cause more severe symptoms (cause severe pneumonia with acute respiratory distress syndrome, multi-organ failure, and death). These are MERS-CoV (Middle East Respiratory Syndrome, or MERS), SARS-CoV (severe acute respiratory syndrome or SARS), and SARS-CoV-2 (coronavirus disease 2019). All viruses are made of a nucleic acid (DNA or RNA) and a protein capsid (that covers the genome). Only some have a lipid envelope.
6. Describe the genome and structure of the coronavirus.
7. What will you do personally to help others understand more about the Coronavirus Disease-19?

Using your textbook, read the section on X chromosome. Then read additional background information on fragile X syndrome at
1. the Human Genome Project site (gov/Genetic-Disorders/Fragile-X-Syndrome“>https://www.genome.gov/Genetic-Disorders/Fragile-X-Syndrome)
2. CDC.gov site (https://www.cdc.gov/dotw/fragile-x/)
Opinions differ about whether children with learning disorders should be tested by karyotyping for the presence of a fragile X chromosome. Some argue that it is always better to know the cause of the problem so that education specialized for that disorder can be prescribed. Others counter that attaching the specific biological cause to a learning disability stigmatizes a child an limits his or her opportunities. Discuss:
1. What is your evaluation of these arguments? Support your answer.
2. Read background information on fragile X syndrome.
