PPT-EOCT Quiz #4 Mitosis, Meiosis, & DNA

Suppose that the anole lizard has fiftytwo chromosomes in the nucleus of its body or somatic cells How many chromosomes will be in the unfertilized egg of an anole lizard 1 13. Unit 5. Welcome Back! . Musical Chairs. TODAY:. Notes on Cell Cycle. Become medical school students on oncology . rotation. Homework for next time: Watch Bozeman video on cell cycle, mitosis and meiosis. There *may* be a quiz.. Sexual Life Cycles. Which of the following transmits genes from both parents to child, or from one generation of a family to another?. DNA. gametes. somatic cells. mitosis. nucleotides. Which of the following transmits genes from both parents to child, or from one generation of a family to another?. Chapter 8. Asexual vs. Sexual reproduction. Asexual reproduction – new organisms/cells are genetically identical to parent cells/organisms . Sexual reproduction – offspring have a combination of genes from both parents. . Mrs. Stewart. Biology I . Stewarts Creek High School. Objectives:. Differentiate between the process of mitosis and meiosis. Demonstrate the movement of chromosomes throughout meiosis. Analyze how meiosis leads to genetic variation. Meiosis Terms . to Know:. Meiosis. : Cell division that produces gametes (sex cells/sperm & egg). These cells are used for sexual reproduction. They have . half . the number of chromosomes as the parent cell.. I. Anaphase I. Metaphase I. Prophase I. Cytokinesis. Images from: http://www.phschool.com/science/biology_place/biocoach/meiosis/teloi.html. What happens. here??. What happens. here??. What type of cell am I??. Mitosis Summary. Class Question. Checkpoints. determine whether cell cycle proceeds or is halted (checks to make sure cell is ready to keep going, checking for errors in replication, growth or division). When is your next paper due?. If you are not sure, you need to. Chapter 10. Cell Division. Cell Division – 2 ½ types. Meiosis – eukaryotes make cells for sex. In humans, “eggs” or “sperm”. Chromatin – the less tightly coiled DNA-protein complex. Centromere – the region of the chromosome that holds the two sister chromatids together during mitosis.. SEX CHROMOSOMES & AUTOSOMES. Sex chromosomes are chromosomes that determine the sex of an organism, and they may also carry genes for other characteristics. . a single . DNA molecule complexed with histone . proteins. DNA is organized within the nucleus as chromosomes. Each chromosome is comprised of subunits called nucleosomes: DNA + proteins. Chromosome numbering/naming. Haploid. Chromosome. Chromatid. Chromatin. Crossing Over. Tetrad. Gene –A segment of genetic information on a chromosome. Codes for a specific . characteristic. Allele – A specific form of a gene. Meiosis is the. . type of . cell division by which . germ cells . (eggs and sperm) . are produced. . One parent cell produces . four . daughter cells. . Daughter cells have half the number of chromosomes found in the parent cell. Learning objective This learning material is about the life cycle of a cell and the series of stages by which genetic materials are duplicated and partitioned to produce two daughter cells with the Levels of Biological organization. Cells  Tissues. Tissues  Organs. Organs  Organ Systems. Organ Systems  Organisms . From zygote to Trillions of Cells. Zygote=Cell that forms when sperm and egg join.
