2 DNA and Genetics

3 - The Cell and Inheritance Gene = group of codons that code for a specific protein Allele = alternate form of a gene A dominant, a recessive both code for the same trait, one from mom, one from dad Homologous pair one from each parent # 1-22, 23 rd is sex chromosomes female XX male - XY

4 Protein Synthesis

5 Transcription DNA code to mrna code occurs in nucleus

6 Translation : Genetic Code to Protein occurs in cytoplasm Active Art build a Protien reduce Power Point to Web

8 DNA Fantastic Song Crash Course Biology : Transcription and Translation

9 Asexual Reproduction Parent cell produces offspring genetically identical to parent. Offspring may look different due to environment. In single-celled organisms and simple animals called binary fission or budding.

13 - The Cell and Inheritance Gene = group of codons that code for a specific protein (order of AA s determines specific shape) Allele = alternate form of a gene A dominant, a recessive both code for the same protein, one from mom, one from dad Homologous pair one from each parent # 1-22, 23 rd is sex chromosomes female XX male - XY

20 Prophase Nuclear Envelope Disappears Chromosomes Appear, Centrioles and spindle forms

21 Metaphase Chromosomes line up on equator. Spindle fibers from centrioles move chromosomes.

22 Anaphase Sister chromatids separate and are pulled to each pole by spindle fibers.

23 Telophase Cell begins to divide. (Cytokinesis) Nuclear envelope reforms Chromosomes back to chromatin. Furrow of Animal cell

24 Mitosis Rap Cytokenesis of Plant Cell Cellulose and lignin are laid down on each side of the cell plate forming a new cell wall at the end of cytokenesis

26 Sperm Pollen Ovule = male Egg 2 gametes parents Sexual reproduction = female - Many organisms produce both gametes (Ex: plants) and sexually reproduce themselves
