5 Questions
What term is used to describe the two strands of DNA based on their base pairing?
Complementary
What is RNA that is complementary to a segment of another RNA molecule called?
Antisense RNA
An organism with an optimal growth rate at very high hydrogen ion concentration is termed as:
Acidophile
Which organisms have more tolerance for acidic pH (lower pH)?
Yeast and moulds
A culture broth tube is very turbid at the surface but clear throughout the rest of the tube, indicating that the organisms are:
Aerobes
Study Notes
DNA Structure
- The bases of one strand of DNA are complementary to the bases of the second strand.
RNA Types
- Antisense RNA is a type of RNA that is complementary to a segment of another RNA molecule and will bind to it.
Optimal Growth Conditions
- An acidophile is an organism that has an optimal growth rate when the hydrogen ion concentration is very high.
pH Tolerance
- Yeast and moulds have more tolerance for acidic pH (lower pH).
Bacterial Growth
- A turbid culture broth tube at the surface but clear throughout the rest of the tube indicates that the organisms are aerobes.
