Microbiology

Question 1

What are viruses made of?

Answer 1

All viruses are made up of a genome(nucleic acids), surrounded by a Protein coat.

Question 2

What do viruses have covering the capsid? What are they called if they are not covering the capsid?

Answer 2

Some viruses have a lipid covering around the capsid, called the envelope. Those without the envelope, are called non-enveloped, or naked viruses are usually more virulent

Question 3

What’s the method of treatment for bacterial infection?

Answer 3

the vaccine is an injection of a harmless form of the virus. Harmless means the viruses weakened or dead.

Question 4

What are the three types of reproduction for bacteria?

Answer 4

Binary fission, conjugation, and endospore formation.

Question 5

What happens in binary fission?

Answer 5

DNA copies go to opposite ends of the cell, invagination of the cell membrane occurs. synthesis of a new cell wall, the result is two genetically similar daughter cells

Question 6

What’s conjugation?

Answer 6

Bacteria’s version of sexual reproduction, a bridge or pili forms between two bacteria one with a plasmid And one without. The whole or partial plasmid is transferred from the donor to the recipient.

Question 7

What’s conjugation?

Answer 7

Bacteria’s version of sexual reproduction, a bridge or pili forms between two bacteria one with a plasmid And one without. The whole or partial plasmid is transferred from the donor to the recipient.

Question 8

What is endospore formation?

Answer 8

When conditions for growth or unfavourable bacteria will produce an endospore within the cell, and become dormant. endospores, are composed of a very thick outer coating surrounding the cell DNA and a portion of the cytoplasm when conditions become favorable. The endospore breaks open and becomes active.
