Question
Hey guys I need some help please
Genetics mitosis and meloshs 1. What was the "point" of the article about Henrieta Lack? 2 Why is the mitotic process NOT a sexual process? 3 te which mitotic phase are duplicated chromosomes fully formed, but attached by the centromeres? 4 Mitotic cells, in animals, divide differently following telophase, than cellular mitotic cells divide in plant cells Explain how these cell divisions are different in animals and plants 5 In which mitotic phase are duplicated chromosomes aligned in the middle of the cel? 6 Sometimes normal cells mutate forming oncogenes. What are oncogenes and what may be produced as a result of this mutatian? 7. In meiosis, crossovers occasionally occur. What is the result of a crossover? What is really heppening when a crossover occurs? L How many cell divisions take place when melosis occurs? What is really happening during these divisions that result in the formation of sex cells? 1 Define the following rvaote/ gamete/ haploid/diploid / germ cell/n- chromosome number /2n chromosome number / germ cell / n chromosome number 10 How many cell divisiohs are necessary in the melotic process? In which stage of melosis does "reduction of the chromosome number occur"? 11 What "Kind" of cell division lmmediately follows fertilization? 12. Do the "Self-Quit" on page 146 13. Gregor Mendel (Chap, 9) provided a mechanism by which variationsin offspring contributed to the evolutionary process. Explain how this is interpreted
Explanation / Answer
Ans-2 mitosis is not suitable because the gametes are haploid cells, while mitosis is a equatorial division. Ans-3 prophase. Ans-5 metaphase. Ans-6 oncogenes are cancer causing gene. Which induce abnormal cell growth. Ans-7. Crossing over produce new combinations. Ans-8 meiosis 1 and meiosis 2
