Cell Cycle/Mitosis/Meiosis Unit 5 Test Review Cell Cycle/Mitosis/Meiosis

Question #1 Looking at the diagram below, what would be the correct order of the illustrated stages of mitosis? B-D-C-A A-B-C-D A-B-D-C B-C-D-A

Question #2 The diagram below illustrates the stages of the cell cycle. Inhibitors stop the cycle at G1 to avoid cells dividing out of control. When mutations take place and do not allow the inhibitors to stop the cell cycle, what can happen in the body? Cell death Deformities Birth defects Cancer

Question #3 Growth and repair of the body cells happen because of ____________. In organisms that reproduce sexually, gametes are produced by _____________. Mitosis; meiosis Meiosis; mitosis Mitosis; conjugation Meiosis; gametogenesis

Question #4 Before mitosis can start, what must happen first? chromosome replication, formation of the cell plate, growth growth of cytoplasm, duplication of cellular organelles, chromosome replication, formation of the cleavage furrow growth, replication of chromosomes, duplication of cellular contents, chromosomal alignment in the middle of the cell growth and duplication of cell organelles, chromosome replication, growth and repair of chromosomal errors

Question #5 What would be the correct order in the diagram below? P-R-Q Q-R-P R-P-Q P-Q-R

Question #6 What is the name of the phase in which cells prepare for division? Prophase Interphase Metaphase Cytokinesis

Question #7 How many chromosomes does a human somatic cell have? 23 46 64 92

Question #8 If an inhibitor cannot stop the cell cycle in G1 and the cell cycle continues to prepare and divide cells uncontrollably, what could develop in the body? Diabetes Extra DNA Extra RNA Tumor

Question #9 For what reasons do cells divide? To make DNA To prevent tumors from being created To make sex cells that will them combine to form offspring For growth, repair and reproduction

Question #10 Organisms begin life as ___________ cells. Haploid Zygotic Embryonic Single

Question #11 Cancer cells can appear in many parts of the body. What could be a possible cause for these cells? Lack of antibiotics given when the first cell appeared Deficiency of vitamins A and C Blood clots Genetic mutation in the somatic cells

Question #12 What is a zygote? A sex cell The combination of a sperm and egg cell A haploid cell A cancerous cell

Question #13 When a zygote develops into a multicellular organism it is because: Protein synthesis is followed by meiosis Meiosis is followed by mitosis Mitosis is followed by cell differentiation Meiosis is followed by cell differentiation

Question #14 If you have a test question that mentions “UNCONTROLLED cell growth”, what type of disease is it making reference to? CANCER

Chromosomes align in the middle of the cell: Metaphase Anaphase Question #15 Chromosomes align in the middle of the cell: Metaphase Anaphase Telophase Prophase

Question #16 Nuclear envelope disappears, chromatin condenses into chromosomes, spindle forms: Metaphase Prophase Anaphase Telophase

Question #17 Nuclear envelope forms at each pole, spindle dissolves, chromosomes uncoil: Prophase Metaphase Anaphase Telophase Cytokinesis

Question #18 Cytoplasmic division: Prophase Metaphase Anaphase Telophase Cytokinesis

Question #19 Which term describes a very long condensed molecule of DNA? Chromosome Gene Helix nucleotide

DNA is often referred to as: Powerhouse of the cell Question #20 DNA is often referred to as: Powerhouse of the cell Control center of the cell Blueprint of the cell Creator of the cell

Question #21 When chromosomes segregate during Meiosis II, the results are: A fertilized sperm cell A group of genetically identical cells The reduction of the number of chromosomes per cell The reduction in the total number of cells per organism

Question #22 What process is illustrated in the diagram below? Crossing over Segregation of sister chromatids DNA replication Mutation of the content of DNA

Question #23 Which of the statements below describes meiosis? It is carried out in all cells for the growth of the individual It is considered the first stage of mitosis It happens in all body cells except for brain and spinal cord cells It happens in the cells of the reproductive organs

Question #24 Interphase is characterized by having three stages G1, S and G2. What event takes place in G1? DNA replication Formation of the spindle Organelle replication Growth of the cell

Question #25 Which process does NOT take place during Prophase? Chromosomes line up in the middle of the cell Coiling of the chromosomes Breaking down of the nuclear envelope Nucleolus disappears

Question #26 If an error took place during mitosis, what could the possible consequence be? Cell death Disturbance in fertilization Mutations that can lead to cancer Both a and c

Question #27 What are the two main stages of cell division? Telophase and cytokinesis M phase and S phase Mitosis and cytokinesis Interphase and mitosis

Questions #28 What event takes place during the S phase that is essential for the daughter cell formation in the M phase? Chromosomes must be joined together DNA replication Cytoplasmic separation Expansion of the cell membrane

Question #29 During cell differentiation, DNA tells the fertilized egg to: Combine with the sperm cell to create many organisms Combine with other fertilized eggs Divide into many organisms that will vary in size Divide into many cells that will vary in function

Question #30 The karyotype below is a: Normal male (no genetic disorder) Male with trisomy 21 (Down Syndrome) Normal female (no genetic disorder) Female with trisomy 21 (Down Syndrome)
