Question
Which of the following statements is true?Plasmids can only be transferred by cell division.Plasmids are found as part of the circular chromosome.Plasmids can replicate independently from chromosomal DNA.Plasmids always contain genes that are vital for survival of the organism.
Solution
The true statement is: "Plasmids can replicate independently from chromosomal DNA."
Here's why:
-
Plasmids can only be transferred by cell division: This statement is false. Plasmids can be transferred between bacteria through a process called conjugation, which does not involve cell division.
-
Plasmids are found as part of the circular chromosome: This statement is false. Plasmids are separate from the chromosomal DNA in a cell. They are small, circular pieces of DNA that exist independently of the chromosome.
-
Plasmids can replicate independently from chromosomal DNA: This statement is true. Plasmids have their own origin of replication and can replicate independently of the chromosomal DNA.
-
Plasmids always contain genes that are vital for survival of the organism: This statement is false. While plasmids often carry genes that can benefit the organism, such as antibiotic resistance genes, they do not always carry genes that are vital for survival.
