Virtual Lab Journal Response Sheet Name: Date: 11th Feb 2015 Name of Virtual Lab Please include the questions. This can be done by highlighting, copying and pasting into the corresponding space Based on your data and observations, what are some of the Differences between normal cells and cancer cells? Based on my data and observations some of the differences between normal cells and cancerous cells are that cancerous cells tend to be more in telophase and that normal cells tend to be more at rest in telophase. Which type of cancer shows the most aggressive growth? Explain.

Ch 13: Meiosis and sexual life cycles Concept 13.1: Offspring acquire genes from parents by inheriting chromosome Comparison of Asexual and Sexual Reproduction In asexual reproduction, a single individual passes genes to its offspring without the fusion of gametes A clone is a group of genetically identical individuals from the same parent In sexual reproduction, two parents give rise to offspring, through the fusion of gametes, that have unique combinations of genes inherited from the two parents Concept 13.2: Fertilization and meiosis alternate in sexual life cycle Sets of Chromosomes in Human Cells Human somatic cells (any cell other than a gamete) have 23 pairs of chromosomes The two chromosomes in each pair are called homologous chromosomes, or homologs

Biology Chapter 11 Cell Division: 11.1 A) Cell Division Cell Division: the process by which a single cell becomes two daughter cells Prokaryotic cells divide by binary fission Eukaryotic cells divide by Mitosis and Cytokinesis Ori = Origin of replication (code for replication ) B) Binary Fission FtsZ, a protein it encodes forms a ring at the site of constriction where the new cell wall forms between the two daughter cells (very similar to Tublin) Cell Division in bacteria and archaeon?s occurs by binary fission Together, mitosis and cytokinesis are known as mitotic cell division. M phase (mitosis and cytokinesis) alternates with interphase, which consists of G1, S (synthesis), and G2?phases. These four stages together constitute the cell cycle.

THE CELL CYCLE-Chapter 12 ? Ability to reproduce = one characteristic of living things ? Continuity of life based on the reproduction of cells ? Cell division functions in reproduction, growth, and repair? UNICELLULAR ORGANISMS use cell division for reproduction? MULTICELLULAR ORGANISMS use cell division to:? -repair/renew cells that die from normal wear and tear? -grow and develop from a single fertilized egg (zygote)? -reproduce asexually (EX: plants grow by cuttings) ? Results in genetically identical daughter cells ? DNA molecules packaged into chromosomes ? GENOME= cell?s genetic information Prokaryotes genome - single circular loop of DNA Eukaryotes - several DNA molecules in multiple chromosome bundles

Chapter 15 The Chromosomal Basis of Inheritance Overview: Locating Genes Along Chromosomes Mendel?s ?hereditary factors? were genes, though this wasn?t known at the time Today we can show that genes are located on chromosomes The location of a particular gene can be seen by tagging isolated chromosomes with a fluorescent dye that highlights the gene Concept 15.1: Mendelian inheritance has its physical basis in the behavior of chromosomes Mitosis and meiosis were first described in the late 1800s The chromosome theory of inheritance states: Mendelian genes have specific loci (positions) on chromosomes Chromosomes undergo segregation and independent assortment The behavior of chromosomes during meiosis was said to account for Mendel?s laws of segregation and independent assortment
