Q1. Which of these statements is true regarding plasmids?

1. Plasmids, which are associated with membrane proteins, depend on bacterial chromosomal DNA for replication.

2. Plasmids are generally circular pieces of RNA.

3. Prokaryotic plasmids may carry genes that provide antibiotic resistance to the cell.

4. Prokaryotic plasmids are NOT passed from one cell to another during replication.

Q2. There are ~2000 G bands visible in a high resolution karyotype of the 3 billion base pairs in the haploid human genome. If the genome contains ~30,000 genes, about how many genes would be removed by a deletion of DNA that might be detected by karyotype analysis?
