The structure of DNA, genes & chromosomes Chromosomes Gene Cell Nucleus Protein
st 1 Flap: Chromosomes • Chromosomes are made of DNA. • Each contains genes in a linear order. • Human body cells contain 46 chromosomes in 23 pairs – one of each pair inherited from each parent
2 nd Flap: Chromatid Pair – When Chromatid Pair chromosomes from your mom and dad join, the pair resembles an “X”. Centromere Upon closer examination, chromosomes are made of fine thread – like substance called DNA. It is wound very tightly. Chromatid
3 rd Flap: DNA resembles a twisted ladder. The twisted ladder shape is called a double helix
The DNA Double Helix
Proteins • Genes are codes for cells to make proteins. • Proteins build things, like eye pigments, freckles, or mood altering hormones. • Proteins are like the recipe for the body’s characteristics.
4 th Flap: Base Pairs The “rungs” of DNA are made of bases. There are 4 bases: § A – Adenine § T – Thymine § C – Cytosine § G – Guanine. A’s only pair up with T’s C’s only pair up with G’s
DNA Base Pairs

Agenda Go over bellringer 1. • 2 nd period only – Complete table 1 2. Complete table 2 of Multiplicity activity. 3. Analysis and Conclusion Questions 4. Mitosis Summary
Table 2: Stages of Cell Division End of Interphase Centrioles The cell making proteins during this time. Chromatin Nuclear Membrane The chromatin is still uncoiled in the nucleus.
Table 2: Stages of Cell Division Spindle Fibers Centrioles Prophase – The long stringy chromatin starts to coil and condense into thick threads called chromosomes. The nucleus starts Chromosomes to disappear.
Table 2: Stages of Cell Division Metaphase – The centromeres of the sister chromatids line up along the center of the cell. Sister Chromatids Centromeres
Table 2: Stages of Cell Division Anaphase – The centromere of each chromosome divides, separating the sister chromatids from each other. The chromatids of each pair will be moved by the spindle fiber towards opposites poles of the cell. Chromosomes The separated chromatids are called chromosomes.
Table 2: Stages of Cell Division Nuclear Membranes Telophase – The final phase of mitosis occurs as new nuclear membranes are formed around both groups of chromosomes. The result is two separate nuclei, each containing the same amount of chromosomes as the original cell.
Table 2: Stages of Cell Division Cytokinesis – The last stage of the cell cycle in which the cytoplasm divides in animal cells. The start of cytokinesis starts with a cleavage furrow. The cell membrane is drawn inward until the cytoplasm is split into two separate parts, forming two distinct cells.
