BIOL 1011 Study Guide - Midterm Guide: Bacterial Conjugation, Pilus, Overlapping Gene
Document Summary
Transformation is the transfer of dna from a donor to a recipient cell. You have carried out a conjugation and discovered that the recipient cells have almost all become donors, but that no chromosomal genes have been transferred. The male cell in the original mating was a(n: avery et al. demonstrated that pneumonia cocci could take up dna directly from the medium surrounding them. This is an example of: transduction, transformation, in one form of dna transfer in bacteria, the dna is transferred from one cell to another in a bacteriophage. Diphtheria-causing bacteria contain a prophage that codes for toxin produced during disease. Chapter 9 questions: streptococcus pyogenes produces a protein that, anchored in the cell wall and cell membrane, allows the bacterial cells to adhere firmly to the pharyngeal tissue. Gram-negative, oxidase- positive cocci were cultured from her cerebrospinal fluid. This condition is called: aschoff bodies, schick syndrome, waterhous-friderichson syndrome, adrenal imbalance syndrome.
