Question

Gram-positive bacteria can be transformed only at __________

Answer 1

Transformation is a process of gene transfer that occurs among bacteria during which DNA encoding for a particular character from one bacterium passes on to another bacterium and incorporated into the genome of recipient bacterium through recombination at crossing over.

In case of Gram-positive bacteria, the transported strand can enter the recipient bacterium with the degradation of its corresponding strand in the host at similar rates, approximately up to 1000 nucleotides. The two events are coupled. However, the whole process of transformation can occur only after competence between the two species involved.
