3 mechanisms of microevolution - natural selection, genetic drift, gene flow 3 modifications made during RNA processing - - adenines added to poly-A tail - 5' end recieves a guanine cap - RNA splicing 3 steps of DNA replication - initiation, elongation, termination active transport - movement of molecules across a plasma membrane against from low concentration to high concentration with the expenditure of energy (ATP) by the cell adhesion - An attraction between molecules of different su...

3 Groups of the Tree of Life - Answer-Bacteria, Archaea, and Eukarya Structure of bacteria - Answer-Circular, 1-2 membranes What is the primary reason the size of bacteria is limited? - Answer-Diffusion Myrobacterium - Answer-Bacterium in which cells aggregate to form fruiting bodies How does bacteria reproduce? - Answer-Only splitting (not sexual), get new genetic information and can acquire it Conjugation - Answer-Direct transfer of DNA between 2 living cells (linear) Pilus - Answer-Phy...

What is the basic unit of all life? Cells All cells must share the features that enable them to what? Perform the functions necessary for life. Robert Hooke Discovered the calls while looking at cork under his microscope. Antoni van Leeuwenhoek First to describe living cells Larger Cells Need more proteins (energy cost) Smaller Cells Can absorb more because their is more surface area to volume Can maintain small size, within itself Two Tenets of the Cell theory 1. All living organi...

FAU Dr. Brooks - Biological Principles - Unit 3 Comprehensive Study Guide 2024 with complete Solutions What is the cell theory? - Answer- All organisms are made come from cells and are made up of cells Cells must reproduce for what 2 reasons? - Answer- Cells must reproduce either to perpetuate the species or create a multi-celled individual Cell reproduction involves which two processes? - Answer- Cell reproduction involves mitosis (duplication and division of the nucleus) and cytokinesi...

G1 Phase correct answer: Preparation for DNA synthesis. Duplicate organelles and systolic compents. (8-10hrs) Cyclin D / CDK 4/6 Checkpoint close to end (RB). S phase costs a lot of ATP. S Phase correct answer: Interphase. DNA replication/synthesis. (6-8 hrs) Cyclin A / CDK2 Between G1 and S correct answer: Cyclin E / CDK2 G2 Phase correct answer: Cell growth to accomodate splitting, enzyme and protein synthesis continue; replication of centrosomes complete. (4-6hrs) Cyc...
