Chapter 10: Sexual Reproduction and Genetics
CHROMOSOMES AND CHROMOSOME NUMBER
-Human body cells have 46 chromosomes
-Each parent contributes 23 chromosomes
-Homologous chromosomes- one of two paired chromosomes, one from each parent
-Same centromere position
-Carry genes that control the same inherited traits
Chapter 9: Cellular Reproduction
-As the cell grows, its volume increases much more rapidly than the surface area.
-The cell might have difficulty supplying nutrients and expelling enough waste products.
Big Idea 1: The process of evolution drives the diversity and unity of life
Enduring Understanding 1.A- Change in the genetic makeup of a population over time is evolution
Essential knowledge 1.A.1: Natural selection is a major mechanism of evolution
DNA, RNA, and Protein Synthesis
-The species-particular DNA sequences produce the species-particular proteins
-Genes code for proteins
-Genes are long strands of DNA of chromosomes
Chapter 7: Cellular Structure and Function
THE CELL THEORY
-All organisims are composed of one or more cells
-The cell is the basic unit of structure and organization of organisms
-All cells come from pre-existing cells
-Contains a plasma membrane
-Does not contain membrane bound organelles
Chapter 6-Chemistry in Biology
COMPOSITION OF MATTER
-Matter-everything in universe is composed of matter.
-Matter is anything that occupies space or has mass
-Mass-quantity of matter in an object
-Weight-pull of gravity on us

? Differentiation yields a variety of cell types, each
expressing a different combination of genes
? Different types of cells make different proteins because
different combinations of genes are active in each type
