BIOD 101 Module 4 Portage Learning Exam With Complete Solutions Chromosomes - structures of packaged chromatin complexes Somatic cell - All of the body's cells except gametes Number of chromosomes in each somatic cell - 46 (23 pairs) Cell cycle - Process of parent cell replicating its genetic info and dividing into 2 new daughter cells cytokinesis - division of the cytoplasm interphase - G1, S, G2 phases. 90% of cycle time. Gap phase 1 - First phase, growth phase Messenger RNA (mR...

Cell cycle The stages that take place between the time a eukaryotic cell divides and the time the daughter cells divide. (stages of growth, preparation, and division (Interphase and Mitosis) Interphase Activities Cell grows, performs its normal functions, and prepares for division G1 In interphase - cell grows rapidly, builds new organelles; also performs regular cell functions S phase The "synthesis" phase of the cell cycle; the portion of interphase during which DNA is replicated. (do...

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

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

heat is a form of? a. kinetic tial c. activation d. catalytic - ANSWER a. kinetic An alpha helix is a type of protein_________ structure? a. primary b. seconday c. tertiary d. quartenary - ANSWER b. secondary the cytoplasmic granule of RNA and protein that reads mRNA and synthesizes proteins is called the _________, an organelle that is not bound by a membrane? a. kinetechore b. Golgi complex c. ribosome d. nucleolus - ANSWER c. ribosome ______________ is not found in DN...

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...

IB Biology: Chapter 1.6 Latest Update Graded A cell cycle all stages in the life cycle of a cell interphase composed of G1, S, and G2; = the growth of the cell. G1 - DNA transcription - protein synthesis (centrioles) - cell Respiration (produces energy) - growth of cell volume - organelles double (mitochondria & chloroplast) -increase in energy stored G0 the stage where cells are unlikely to divide (ex: neurons) S - synthesis of genetic material - DNA replication - dup...
