Recombinant DNA technology uses certain biotechnology processes to insert nonrelated genes into recipient cells. It has provided medicine by producing human insulin in bacterial cells.
a) Discuss why conjugation has an advantage over other means of lateral transfer because it donates genetic material through cell-to-cell contact.
Homework Answers
Conjugation has an advantage over other means of lateral gene transfer because in this method of genetic transfer between bacterial cell by direct contact. Therefore, it is fast and reliable as compared to other means of lateral transfer.

Bacterial cells, such as E. coli, are surrounded by a fluid plasma membrane and enclosed by a rigid cell wall that protects the cell from damage. You will recall that there is no nuclear envelope in prokaryotic cells, but rather a “nucleoid region” with a single chromosome that is continuous (circular), not linear, as in eukaryotes. All of the genes required for basic survival and reproduction are found in the main chromosome. In addition to the main chromosomes, some DNA...

1. The type of genetic exchange between bacterial cells that can happen between isolated DNA and a live bacterial cell is: a. conjugation b. transduction c. transversion d. transformation 2. An Hfr strain of E. coli with genotype a+b+c+d+e+f+ is mated with an F¯ auxotrophic strain with the genotype a¯b¯c¯d¯e¯f¯. Conjugation is stopped at 10 minute intervals and the genotypes of the resulting conjugants are determined. The following results are obtained: after 10 minutes e+ after 20 minutes a+ e+...
