1. What is a capsid?

the protein coat or shell of a virus particle, surrounding the nucleic acid or nucleoprotein core. Allow the virus to bind to host cells

2. Viral envelope?

covers the protein capsid, derived from proportions of the host cell membrane, help viruses enter host cell

3. What is the lytic cycle of viral replication?

The lytic cycle is typically considered the main method of viral replication, since it results in the destruction of the infected cell

4. What is the lysogenic cycle of viral replication?

The lysogenic cycle replicates the phage genome without destroying the host

5. What is a retrovirus?

A virus whose genes are encoded in RNA instead of DNA

6. Is HIV a retrovirus?

yes

7. What
   enzyme do retroviruses have?

They contain the enzyme reverse transcriptase

8. What is a genomic library?

also clone bank or gene bank, is a collection of DNA from a single organism

9. What is genetic engineering?

refers to a set of technologies that are being used to change the genetic makeup of cells and move genes across species boundaries

10. Biotechnology?

generally accepted as the use of living systems and organisms to develop or make useful products to make or modify products or processes for specific use
