what is the lytic cycle?

i looked online and they give all of these confusing answers!!! i found this, but it doesnt make sense
•Attachment of virus to host cell
•Infection of DNA/RNA into the host cell
•Virus turns off the host cell’s genes
•Host cell manufactures the proteins and DNA/RNA
•Assembly of the viruses from proteins and DNA/RNA

2 bio multiple choice questions 10 points!!!!!!!?

A.Airborne bacteria with the healthy gene are inhaled.
B.CF patients are infected with a virus containing the healthy gene.
C.Healthy genes are inhaled as free DNA fragments in an air sample.

Is the H1N1 vaccine going to turn us all into zombies?

My friend, who does those Tea Parties, says that he thinks the H1N1 virus is a hoax and that the vaccine will make us into Obama loving zombies. He said that Obama is behind the whole thing because he is a dark and evil person.

If you are a virologist, how will you combat a specific viral strain aside form vaccine?

if you are a virologist, how will you combat a specific viral strain aside from vaccine, when the virus attacking cyto-toxic-Tcells?

In Gene therapy, is defective gene being replaced by healthy one?

Or just the new healthy gene is being added using virus as a vector without removing non functional gene?

What are the side effects of the h1n1 vaccine?

It’s a new drug so I’m unsure whether or not it’s safe. I remember there was a vaccine for a similar virus in the 80-90s and it had MANY side effects.

Can you please link me to credible sites? Or your opinion. Thanks!

President Obama’s Council of Advisers on Science and Technology predict half the country will be infected by?

the mexican flu (I call it such based on origin and the fact that avian and human dna also make up this virus), and that 90 thousand will die.

"The report, which claims as many as 1.8 million people could end up in the hospital seeking treatment"

some private doctors do not appear to like the rush.

""Trying to rush in with an unknown, with an untested quantity of vaccine doesn’t appeal to me at all," said Dr. William Schaffner, a professor of preventive medicine at Vanderbilt University."

QUESTIONS:

What are your thoughts on the article in general?

Is it blown of of proportion and if so, why?

What are your thoughts on the massive amounts of untested vaccines?

Are you concerned over the issue?

Which statement below is a correct statement about ex vivo gene therapy?

Which statement below is a correct statement about ex vivo gene therapy?
A. DNA is directly injected into the body to treat disease.
B. Bacteria are used to carry new DNA into cells removed from body.
C. Body cells are incubated with DNA and take it up on their own.
D. Body cells are infected with a virus carrying the new DNA.

Can someone who received a H1n1 vaccine give the illness to someone who has not?

Since some of the vaccines are a mild form of the live virus and some are a dead virus and you have it in you, are you contagious if you got the vaccine?
