BSC1010C Name: Kyle Silver Unit #4 Homework Summer 2013 Below are three 5 question, matching activities, 1-5, 6-10, and 11-15. As matching activities, each answer will be used once in each set of 5 questions. The entire homework is 60 questions. Consider the cell cycle of any multicellular eukaryote organism undergoing its normal life cycle and experiencing everything normally. Also, recognize each answer needs to be appropriately general or appropriately specific in order to properly complete the set of questions as a matching activity. 1) D Mitosis A – this is the cell cycle stage general cell development, maturation, and growth 2) C S B – this is not a cell cycle stage rather it is the designation of cells which are mature and normally do not reproduce 3) A G1 C – this is the cell cycle stage of DNA replication; chromosomes are copied in this stage 4) E G2 D – this is the cell cycle stage of nuclear division and also cell division; cell cycle stage that cellular reproduction 5) B G0 E – this is a cell cycle stage specifically oriented to preparation for cellular reproduction Match the genetics terms 6 – 10 with the correct description A – E. Each is used once. Also, recognize each answer needs to be appropriately general or appropriately specific in order to properly complete the set of questions as a matching activity. 6) D genotype A – the characteristic of an organism that is in part due to its alleles 7) A phenotype B – an organism’s total compliment of chromosomes generally expressed in terms of ploidy and quantity 8) E heterozygote C – a diploid organism with two identical alleles for a gene 9) C homozygote D – an organism’s combination of alleles for a gene 10) B karyotype E – a diploid organism with two different alleles for a gene Please match the following events of mitosis, A – E, with the correct mitosis subphase, 11-15. Each response A – E is used once per # substage. 11) A metaphase A –chromosomes with 2 chromatids line up at the midline of the parent cell 12) C telophase B – chromatin is further condensing as chromosomes appear; microtubules are attaching to and beginning to sort chromosomes 13) E prometaphase C – nuclear envelope reforms; chromosomes ‘uncondense’ reforming chromatin chromatin 14) B prophase D –chromosomes with 1 chromatid are migrating to what will be each daughter cell 15) D anaphase E – chromatin begins condensing into chromosomes; spindle is maturing with microtubules extending to chromosomes

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
