12 Questions
What is the main difference between Gram-positive and Gram-negative bacteria?
Differences in the structure of the cell wall.
What does VBNC (Viable but Non-Cultivable) refer to in marine microbiology?
Bacteria that exist but cannot be cultured using standard techniques.
What do molecular methods involve in marine microbiology?
Analysis of DNA, RNA, and proteins to describe microbial communities.
Why is RNA better suited for studying the function of a type of bacteria compared to DNA?
RNA can make copies until it produces the required protein function.
What is the main function of Taq polymerase in PCR (Polymerase Chain Reaction)?
Making copies of DNA segments during the PCR process.
Why is the 16S ribosomal RNA gene often used as a gene marker in bacterial studies?
It has high variability across different bacterial species.
What is the target of bacterial gene identification and why does it have high variability?
Single species identification
What is the difference between environmental DNA (eDNA) and general DNA?
General DNA is isolated from the environment, while eDNA is DNA from inside the cell
What is the impact of molecular biology on marine microbiology?
Insight into microbial ecology and physiology
What does 'omic' sciences involve?
Exploring DNA and RNA to understand bacterial functions
Why are microbes important for the food web?
They help in waste decomposition
How can microbes help reduce oil pollution in the ocean?
By feeding on oil particles
