Which of the following statements about using transduction f

Which of the following statements about using transduction for mapping genes on the bacterial chromosome are true? Check all that apply Transduction mapping can be used to determine the order of several genes. Genes that are located close to one another on the chromosome have a higher probability of being transduced together Transduction studies require the direct contact between bacterial cells Transduction mapping is based on the fact that phages can transfer two genes simultaneously.

Solution

Ans options A , B and D are correct

Transduction does not require direct contact of bacterial cells, it takes place usually through a viral vector.

Genes located closer on the DNA are transduced together (cotransduced). By knowing the cotransduction frequency, the relative proximity of the these genes can be concluded.
