Microbiology FINAL Review (Jersey College) Questions and Answers | Latest Update | 2024/2025 | 100% Verified What is the primary function of the bacterial cell wall? The bacterial cell wall provides structural support and protection to the cell, maintaining its shape and preventing osmotic lysis. Describe the role of plasmids in bacterial cells. Plasmids are small, circular DNA molecules that replicate independently of the chromosomal DNA, often carrying genes that confer advanta...

Portage Learning BIOD 171 Microbiology Lecture Exam Key 1-6 Exams 1. What are the two major types of nucleic acids and their roles? DNA- deoxyribonucleic acid RNA- Ribonucleic acid DNA- Cellular life has DNA and a role that DNA has is long-term storage of information, it holds the characteristics of living organisms. RNA- Is the carrier of information in form of amino acid sequence. It converts the information in the DNA and synthesizes proteins Tru...

WGU D311: Microbiology with Lab: Section 1 Describe the lytic cycle in bacteriophages. ️️ In the lytic cycle, a bacteriophage attaches to a bacterial cell, injects its DNA, uses the host’s machinery to replicate and assemble new viruses, then lyses the cell to release them. What is the significance of Koch's postulates? ️️ Koch's postulates are a set of criteria to establish a causative relationship between a microbe and a disease, helping to identify pathogens respon...

True or false: An increase in genome complexity results in an increase in structural and metabolic complexity. - True! More complex organisms have more complex, and usually larger, genomes. What are the stages of bacteriophage assembly? - 1. Infection: Phage attaches itself to bacterial surface and injects its genetic material into the cell. 2. Replication of genetic material: Virus uses the host cell's machinery to replicate its genetic material. 3. Production of viral proteins: Host ce...
