D All previous answers are correct.

. The plasmids bear the genes that give the bacterium genetic benefits such as antibiotic resistance not the genes for essential activities. Which of the following statement about plasmid is correct. Restriction enzymes can cut plasmid DNA at specific nucleotide sequences Plasmids like all.

Plasmids are linear pieces of DNA O d. Plasmids are not part of genomic DNA. Correct option is D Plasmids are the circular forms of DNA that are present as extra genetic material in the bacteria.

I It can replicate by itself II Hybrid plasmid is introduced into bacteria by transformation III Other than bacteria plasmid can also be found in bacteriophage. Which one of the following statements is correct regarding the oral microflora. The correct option is C.

Plasmid can be transmitted from one bacterium to another. B Resistance to some drugs is due to a chromosomal mutation that alters the receptor for the drug. Which of the following statements regarding plasmid-cloning vectors is correct.

Plasmids are circular pieces of DNA that contain genetic information. See the answer See the answer done loading. Plasmids replication occurs at the same time as the chromosome is being replicated.

Circular plasmids do not require an origin of replication to be propagated in E. All of the answer choices are correct. Plasmids do not need to contain genes that confer resistance to antibiotics.

When a plasmid is cut at only one location by a restriction enzyme the result is a linear double-stranded piece of DNA that is the same size as the plasmid c. Which of the following statements regarding plasmids is correct. A R factors are plasmids that carry the genes for enzymes that modify one or more drugs.

These are self-replicating structure and do not depend upon host enzymatic activities for their application. C R plasmids are usually narrow host range plasmids. All of the following are true statements concerning plasmids EXCEPT.

BThey can be found in bacteria fungi and protozoa. It provides special characteristics to the bacterial cell-like surviving in presence of antibodies reproductive capacity etcetera. Plasmids can be used as cloning vectors to amplify genes O b.

A R plasmids are commonly found in bacteria isolated in the hospital. Plasmids are sites for inserting genes for amplification. E R plasmids code for resistance genes and resistance transfer factor.

Hence 1 3 4 are correct while 2 5 are incorrect. They confer properties like antibiotic resistance to the bacteria or to the organism in which they are present. Plasmid can be genetically engineered O e.

B R plasmids usually encode resistance to more than one antimicrobial medication. All of the plasmids are usually made up of double-stranded circular DNA molecules. Inside a cell it is a small extrachromosomal DNA molecule that is physically isolated from chromosomal DNA and can independently replicate.

Bacteria can have 100 copies of a plasmid. 1 3 4 Plasmids are extra-chromosomal self-replicating circular double-stranded DNA molecules present in bacteria. Mark all correct responses a.

D R plasmids may code for resistance to heavy metals. Plasmids can be transferred from bacteria to other bacteria. Each of the following statements concerning the mechanisms of resistance to antimicrobial drugs is correct EXCEPT.

Therefore the correct answer is option A. All of the answer choices are correct. Foreign DNA fragments up to 45000 base pairs can be cloned in a typical plasmid.

Plasmids are circular and supercoiled pieces of DNA that are found in bacteria b. AThey can carry genes that confer resistance against antibiotics. Plasmids may be transferred between different species of bacteria.

Plasmids are circular molecules of DNA. Mutans will begin to be detected mainly between the. Unlike the chromosomal DNA they are present in a confined region in a circular defined shape.

Let us understand each given statement in context to plasmids to know whether they are correct or incorrect-Option A says that plasmid has circular DNA. Plasmids usually contain genes for one or more traits that may be beneficial to bacterial survival O c.
