Which of the following refers to the uptake of naked dna from the surrounding environment?
conjugation
generalized transduction
specialized transduction
transformation

The correct answer will be option- transformation.

Explanation:

The transformation is the process of the horizontal transfer of gene in which the competent cells takes the naked DNA from the environment.

This process was reported in the experiments of Griffith on Streptococcus pneumonia in 1928. The bacteria should be competent to take up the free extracellular DNA form the environment. This ability of the bacteria is used in biotechnology and molecular biology in cloning procedures and many others.

Thus, option- transformation is the correct answer.

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.
