MIP 302 Exam 1 Questions with All Correct Answers What is viral cultivation? - Answer-The replication of a virus in living cells What is the main necessary component of viral cultivation? - Answer-Living cells Describe the setup of the plaque assay. - Answer-E. coli is mixed with a bacteriophage in a TSA then poured into a plate; the E. coli form a bacterial lawn then the phages infect the E. coli cells and lyse them, forming the plaques Why did you dilute the phage stock in the pla...

the purpose of the development of a vacuole is correct answers digest food, regulate excess water and regulate internal environment if a virus that normally infects cells in the lining of an elephant's lungs enters a rhinoceros correct answers it cannot infect the rhinoceros because a virus is specific to a cell type and a species photoheterotrophs get their energy from blank and their carbon source is correct answers light carbon source chloroplast arose twice on a phylogentic tree ma...

BTECH Review Exam 2 Questions & Answers 2024/2025 what applies to bacteriophages? - ANSWERSBacteriophages recognize molecules on bacterial surface to infect All phages use the hosts replication machinery to some extent Most phages have narrow host range Bacteriophage genomes can be RNA, but mostly DNA In vitro transcription of the SARS-2 spike gene makes use of the __________ - ANSWERST7 gp10 promoter The antirestriction protein of T7: - ANSWERSprotects T7 DNA from bacterial...

Hershey and Chase performed an experiment in order to determine how bacteriophages infect bacteria. What did they find? The bacteriophage injects DNA into the host cell. This was found because, after centrifugation, the pellet was radioactive The largest difference between a Gram + and Gram - bacterial cell is: The gram + cell has a much thicker peptidoglycan layer Why does a Gram + cell stain blue/purple in a gram stain? The Gram + cell stains blue/purple because crystal violet rem...

Portage Learning BIOD 171 Module 6 Exam Questions and Answers 2024 True or False: viruses can be classified as prokaryotic or eukaryotic -Answer-False. Viruses are neither prokaryotic or eukaryotic What is an obligate intracellular parasite? -Answer-viruses cannot replicate unless inside a living host cell. As a parasite, a virus depends on its living host to provide the framework (proteins, etc) to replicate—to make additional copies of itself. What is a viral capsid? -Answer-a membran...

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...

MICROBIOLOGY EXAM 2/ REVIEW QUESTIONS AND ANSWERS, GRADED A+ Are Viruses Living or Nonliving? - -They are only considered living when they are inside of a host cell, using their resources and energy. Outside of a host they are considered intert. When are Viruses considered to be "alive"? - -When they are inside of a host cell. When inside, their nucleic acid (ONLY RNA OR DNA) become active. *Virus replicates Obligatory Intracellular Parasites - -Require livinghost cell in order to ...
