Plasmids __________.
A
replicate independently of the main chromosome
B
often contain antibiotic resistance genes
C
are transferred from one bacterium to another by conjugation
D
can be involved in transfer of genetic material between prokaryotic cells
E
All of the listed responses are correct.
Verified step by step guidance
1
Understand what plasmids are: Plasmids are small, circular DNA molecules found in bacteria that are separate from the chromosomal DNA. They can replicate independently within the bacterial cell.
Recognize the role of plasmids in antibiotic resistance: Plasmids often carry genes that provide resistance to antibiotics, allowing bacteria to survive in environments with antibiotic presence.
Learn about plasmid transfer through conjugation: Conjugation is a process where genetic material is transferred between bacterial cells through direct contact, often involving plasmids.
Explore the involvement of plasmids in genetic material transfer: Plasmids can facilitate the transfer of genetic material between prokaryotic cells, contributing to genetic diversity and adaptation.
Conclude that all the listed responses are correct: Plasmids replicate independently, contain antibiotic resistance genes, are transferred by conjugation, and are involved in genetic material transfer between prokaryotic cells.
