What does the cell theory state? - ✔✔
1. all organisms are made up of cells
2. cells are the basic units of structure and function in organisms
3. cells come only from preexisting cells because cells are self-reproducing
All cells include what 4 things? - ✔✔
1. DNA
2. Cell membrane
3. Cytoplasm
4. Ribosomes
What is the central dogma? - ✔✔It's the basic flow of information in a cell, it's the two step process of
transcription and translation by which information in the genes flow into proteins.
What is the purpose of the cellular membrane? - ✔✔To control the movement of materials into + out of
the cell
What are the 3 domains of life? - ✔✔Bacteria, Archaea = prokaryotes
Eukarya = Eukaryotic
What does metabolism mean? - ✔✔The chemical reaction by which cells convert energy from one form
to another
ATP allows cells to do what? - ✔✔Growth, division + moving substances in and out of the cell
, What are some traits of prokaryotic cells? - ✔✔
- Does not have a membrane bound nucleus (it has a nucleoid region)
- Much smaller then Eukaryotic cells
- No organelles
- Different promoter recognition
- DNA is a single circular chromosome
What are some traits of eukaryotic cells? - ✔✔- Has a membrane bound nucleus
- Cholesterol is present in the cell membrane
- Much larger then Prokaryotic cells
- Contains organelles
- DNA is linear
What are some traits that Prokaroytic and Eukaryotic cells share? - ✔✔- Contain protein, water and DNA
- Contain Ribosomes
- Has a cellular membrane
What are the 4 major categories of macromolecules in cells? - ✔✔1. Protein
2. Nucleic Acid
3. Lipids
4. Carbohydrates
What is the monomer of Protein + what is its bond? - ✔✔Monomer: Amino Acid
Bond: Peptide bond
What is the directionality of protein + the reason for it? - ✔✔The amino group (of one amino acid)
attaches to the carboxyl group of another amino acid
= "N" terminus (is how it starts) to "C" terminus (how it always finishes)
