Study Notes
Scientific Method
- The first step of the scientific method involves making observations.
- The next steps include forming a hypothesis, performing an experiment, and predicting the result of the experiment.
Biology Terminology
- Antiretroviral drugs reduce the spread of HIV within a person by blocking enzymes involved in the entry phase, reverse transcription, and protein synthesis.
- In a biology laboratory, a plant press is a useful equipment.
- Viruses differ from other cellular organisms in that they do not possess cellular organelles, have circular DNA, and reproduce inside the host.
Microscopy
- The minimum distance of which a microscope is capable of distinguishing two points as separate is its resolving power.
Biology of Plants
- A very strong structural molecule in plants is formed by hydrogen bonding between chains of glucose molecules, which is cellulose.
- In biology, starch is formed by hydrogen bonding between chains of glucose molecules.
Bacteriology
- Gram-negative bacteria stain pink with Gram's stain.
- Bacilli is a bacterium that belongs to prokaryotes.
- In bacteriology, peptidoglycan is a polysaccharide that acts as the strengthening material of a bacterial cell wall.
Molecular Biology
- In DNA, the "uprights" of the ladder are made up of sugar and phosphate.
- mRNA code is converted into a polypeptide chain through translation.
- Transduction is the process by which a virus carries a plasmid from one cell to another to exchange genetic information.
Ecology
- Carrying capacity refers to the maximum number of individuals that a given environment can support over a long period of time without degradation.
- Inter-specific competition is competition between members of different species in the same ecosystem.
Biotechnology
- Genetic engineering to improve plant growth is an example of biotechnology.
- Transduction is a process that shows the significance of biotechnology.
Genetics
- Inheritance is a fundamental concept in genetics, where traits are passed down from one generation to the next.
- Mendel's experiment showed that the purple flower color is a dominant character.
Cell Biology
- Metabolism is the chemical process of living organisms that involves both the joining up of monomers to produce polymers and the splitting of polymers to monomers.
- Universal code is a property of the genetic code that defines the genetic code for a specific amino acid similar to all kinds of organisms.
Evolution
- Drosophila (fruit fly) is a convenient experimental animal in genetics because it has only four pairs of chromosomes per cell.
- Homologous chromosomes carry alleles of the same genes at different loci.
Biochemistry
- Glycogen is the most abundant polysaccharide found in animals.
- Enzymes are biological catalysts that are specific to only one kind of reaction because each enzyme has a unique shape.
Fossils
- Fossils can be classified into different types, including bone fragments, teeth fragments, plant body impressions, and more.
Energy
- Activation energy is the energy that needs to be provided to get a chemical reaction started.
Protein Synthesis
- During protein synthesis, tRNA molecules transport amino acids to their correct positions in the group chains of polypeptide.
Hormones
- Peptide hormones are a type of hormone that helps regulate various bodily functions.
