Reproduction Objective: L.8.2.A I Can Explain the relationship among genes, chromosomes, & DNA as well as their relationship … to inherited characteristics Cell Theory: 3 parts 1. All living things are made of cells. 2. Cells are the basic and fundamental building blocks of life 3. All come from pre-existing cells. What is the purpose of reproduction? Reproduction is the process of producing a new organism. Reproduction also allows for growth and replaces worn out or damaged cells. The main purpose of reproduction is for survival of a species by transferring DNA What is DNA’s role in reproduction of cells? Performance Objectives: L.8.2A.1 Obtain & Communicate information about the relationship of genes, chromosomes, & DNA. Construct explanations comparing their relationship to inherited characteristics DNA (Deoxyribonucleic Acid) DNA is the chemical inside cells that contains hereditary information In Eukaryotic it is found in the nucleus Plants and animal In Prokaryotic cells it is found within the cytoplasm bacteria Structure of DNA Shaped like a twisted ladder The sides of the ladder are made up of sugar-phosphate molecules The rungs of the ladder are made up of nitrogen base pairs There are 4 Nitrogen Bases that make the Rungs (steps) of the ladder – Adenine always bonds to Thymine Guanine always bonds to Cytosine DNA is like blueprint or instructions Controls how an organism will look & behave act as a messenger carrying instructions from DNA in the nucleus to the ribosome for making RNA proteins that build specific traits Chromosomes Chromosomes are rod-shaped or threadlike structures made of tightly coiled DNA typically containing thousands of genes that hold hereditary information Different organisms have different numbers of chromosomes Diploid cells have a full set of chromosomes 46 for humans Haploid cells known as gametes or sex cells have a half set of chromosomes 23 for humans A karyotype is the number and appearance of chromosomes in the nucleus of a eukaryotic cell.
