How is cell division possible in eukaryotes versus prokaryotes? - Answer-*Eukaryotes* - Mitosis - > somatic cells - Meiosis -> gametes *Prokaryotes* - Binary fission What is the outcome of Mitosis/Cytokinesis? - Answer-A parent cell is divided to create two identical daughter cells to the parent and each other (clones) What are the three functions of Mitosis? - Answer-1) Growth 2) Repair/ Replacement 3) Asexual Reproduction What is a chromosome? - Answer-- A structure carrying ge...

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...
