Study Notes
Experimental Design
- The dependent variable is the outcome or response being measured in an experiment.
- The independent variable represents the factor being manipulated or changed in an experiment.
- The controlled variable provides baseline information about the dependent variable.
Griffith's Experiment
- Frederick Griffith mixed harmless bacteria with material from heat-killed dangerous bacteria, resulting in the transformation of the harmless bacteria into a pathogenic form.
- This experiment was conducted by a group of scientists, including Frederick Griffith.
Enzymes
- Enzymes that destroy DNA and proteins, respectively, were discovered by scientists.
- These enzymes play a role in destroying DNA and proteins.
DNA Structure
- The 5’ carbon atom of the sugar in DNA plays a crucial role in its structure.
- The two strands of DNA are held together by hydrogen bonds.
- Adenine (A) is a purine nitrogenous base.
Sickle Cell Disease
- A difference in 1 amino acid of the 300 amino acids that make up the beta subunit leads to Sickle Cell Disease.
Genetics
- The question "What is genetic material?" falls under the topic of genetics.
- Erwin Chargaff's work in 1952 primarily contributed to the understanding of the structure of DNA in genetics.
Proteins
- Most cellular processes that depend on proteins are essential for maintaining cellular function.
