BIO 115 FINAL (Barry) WVU LATEST VERSION GRADED A+ scientific theory an explanation for a very general class of phenomena or observations that are supported by a wide body of evidence hypothesis -must be testable -must be falsifiable -is a proposed explanation for an observation mitotic spindles come out of centrosomes kinetochore microtubules spindle fibers that attach to the kinetochore (center) of chromosome non-kinetochore microtubules spindle fibers that attach to sp...

Meiosis lead to the production of ________. - Gametes Mitosis leads to the production of ________. - Somatic cells What are the functions of mitosis? - Growth, repair/replacement, and asexual reproduction in planaria. What is the G1 stage responsible for? - Cell growth, transcription/translation, duplication of organelles, and to prepare for DNA replication. What is the S phase of interphase responsible for? - DNA replication. It only occurs during this phase. What is the G2 phase...

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...

Interphase - cell grows, performs its normal functions, and prepares for division; consists of G1, S, and G2 phases G1 phase - the cell grows in size and organelles double in size S phase - DNA replication ("S"= synthesize) G2 phase - cell growth, production of enzymes and other proteins two categories of mitosis - 1. karyokinesis (division of cell nucleus) 2. cytokinesis (division of cytoplasm) prophase - 1. chromatin condenses to form chromosomes; nuclear membrane and nucleoli disapp...

what structures comprise the mitotic spindle? how do they behave during mitosis? - ANSWER the mitotic spindle is composed of microtubules and centrosomes -non-kinetochore microtubules aren't attached to a chromosome; kinetochore is the protein that binds the microtubule to the chromosome -asters: radial array of short microtubules what structures are involved in cytokinesis for animal cells? plant cells? - ANSWER animal cell: -cytokinesis occurs when the plasma membrane forms a cleavage f...
