Somatic (body): most of body tissue and organs. Germ: found in reproductive organs, develop into gametes. Gametes are sex cells – ova (eggs) & spermatozoa (sperm). 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. 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. Interphase. Cytokinesis. Telophase. Anaphase. Metaphase. Prophase. Mitosis. Meiosis. What looks similar between mitosis and meiosis?. What looks different?. Vocabulary- Meiosis. Process of reduction . 1. MEIOSIS AND SEXUAL LIFE . CYCLES. Heredity. = Continuity of biological traits from one generation to the . next. Variation. = Inherited differences among individuals of the same . species. Genetics. These phenomena observed in Saccharomyces cerevisiae are highly conserved in eukaryotes, thus rendering yeast, which is easy to use, an essential model organism. Researchers identified and studied fun 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.
