Question

The ability of bacterial cells to take up DNA fragments from surrounding is called. a)Transfection. b)Transduction. c)Transformation. d)congulation​

Answer 1

Answer:

other than option (a) all are correct

Answer 2

The ability of bacterial cells to take up DNA fragments from surrounding is called c)Transformation

• Transformation is defined as the direct uptake of external genetic material from the surroundings. The genetic material passes through the cell membrane into the cell. Electroporation and chemical bombardment are the methods used to achieve transformation.
• Transfection is defined as the introduction of genetic material into the eukaryotic cell. The process is deliberate. Gene gun technique, use of chemical like calcium phosphate is used for transfection.
• Transduction is the introduction of genetic material via viral vectors. This method is also deliberate. It uses biological agents like viruses for introducing nucleic acids.
• Conjugation is the method of gene sharing between bacteria. The bacteria come in direct contact to transfer the genetic material to other bacteria. The process involves fertility factors to enable the transfer of genetic material.
