Which of the following is the additional DNA found in some bacteria that replicate independent of the cell division?
Group of answer choices
Nucleus
Nucleoid
Plasmid
Chromosome
Nucleosome
Homework Answers
plasmids are extra-chromosomal circular DNA, Plasmid contains Ori C, the origin of replication so plasmids can replicate by its own and increase it`s copy number, independent of cell division so the answer is Plasmid.

Recently an antibiotic resistant strain of bacteria was found to possess a plasmid containing a unique drug resistance gene. Scientists and physicians are extremely concerned about this discovery since this drug resistance gene is usually only found as a part of the bacterial chromosome (nucleoid). In 1 bullet point --Explain the differences between chromosomal DNA (nucleoid) and plasmids. In 2 bullet points -- Explain why the medical community is so concerned about the the discovery of this particular antibiotic resistant...

Please classify each statement as describing transformation, conjugation, or transduction in bacteria. Bacteria can acquire plasmids from outside the cell. A bacterium that contains an F plasmid connects to a recipient bacterium that lacks an F plasmid with an appendage called a pilus, through which the plasmid is transferred. Some bacterial DNA fragments may be included when new phage particles are assembled. A cell can be treated to make it competent to take up DNA from its environment. When a...

Bacterial cells, such as E. coli, are surrounded by a fluid plasma membrane and enclosed by a rigid cell wall that protects the cell from damage. You will recall that there is no nuclear envelope in prokaryotic cells, but rather a “nucleoid region” with a single chromosome that is continuous (circular), not linear, as in eukaryotes. All of the genes required for basic survival and reproduction are found in the main chromosome. In addition to the main chromosomes, some DNA...

The Hershey Chase experiment using radioactively labeled bacteriophage to infect bacteria proved that DNA was the genetic material. If you were reviewing those experimental results, which of the following would provide evidence that DNA was the genetic material? Select all that would apply. a) The DNA was localized in the cytoplasm of the bacterial cell, which is the same site that the bacterial chromosome is located. b) Radioactively labeled viral proteins were only found outside the cell and the viral...
