Textbook Question
Chapter 15.L2, Problem 3CT
Double-stranded DNA is a large, complex molecule, but it is not generally immunogenic unless it is associated with proteins or carbohydrates. Can you think why this might be so? (Hint: How universal is DNA?)

Bacteria have evolved numerous mechanisms to prevent the invasion of foreign viral DNA (see Bacterial Defense Mechanisms). Yet clearly some bacteria have evolved competence, the ability to take up foreign DNA from the environment. Why do bacteria take up naked DNA from the environment and yet exclude DNA from viruses?
In a [1] infection, the viral DNA is inserted into the host cells DNA. it remains there and is copied each time the cell multiplies.
The kind of DNA you inherit only from your mother (because only eggs have it, sperm don't have it) is called:
Group of answer choices
messenger DNA
transfer DNA
maternal DNA
mitochondrial DNA

The patient explains to the doctor that he was at a concert the night before and shared a water bottle with a friend who had similar symptoms. The doctor tells the patient that he has a virus. a.) What form of replication do you think this virus does use? How do you know? b.) Can the doctor prescribe an antibiotic for this patient? Explain.arrow_forward

Answer in 2-3 sentences.arrow_forwardAfter a positive strand RNA virus ( Such as Coronaviruses) enters the host cell, the RNA is translated by ribosomes to create proteins associated with the virus (Such as, for example, the surface antigens like E and Spike proteins). How then, would the genetic material itself be replicated to be incorporated into the new viruses?.arrow_forwardViruses are host-specific, meaning they can only infect specific types of host organisms. For examble, the adenovirus is responsible for the common cold in humans but your dog can't catch a cold from you. Why is this? The proteins on the virus surface can only bind with proteins on the correct host surface. It is an enveloped or non-enveloped virus. The enzymes carried by the virus are compatible with the host. The genome of the virus is made of DNA or RNA.arrow_forward
