Part 1: Core Genetics
Part 1 resources on Core Genetics take learners through a collection of lessons to help them learn what genetics is and how genes are inherited or passed on from one generation to the next.
Just the facts
Description of the fundamental concepts of trait inheritance in sexually reproducing species.
DNA and Chromosome Structure
This lesson describes the chemical structure of DNA and how the structure relates to genes and chromosomes. The replication of DNA prior to cell division to create the chromatids of replicated chromosome is illustrated, showing how the main DNA replicating enzymes work together in living cells.
Mitosis and Meiosis and the Cell Cycle
Multicellular organisms such as plants and animals are composed of millions to trillions of cells that work together. This lesson details the steps of somatic cell division to produce identical cells by mitosis and germline cell division to produce gametes by meiosis. Emphasis is on what is happening genetically as these new cells are made in multicellular, sexually reproducing organisms.
Gene Expression Part 1: Reading Genes to Make Proteins
This lesson describes the steps involved in a cell as DNA sequence information is read to make RNA and RNA is read to make proteins.
Gene Expression Part 2: Expression of Herbicide Resistant ALS Genes in Plants
This lesson describes how changes in the DNA sequence of a gene can alter the synthesis of a protein and thus influence traits such as herbicide resistance.
Segregation of Genes: The Plant Breeder's Method of Predicting the Future
How plant breeders create families with new combinations of traits and make predictions about the inheritance of traits. Discusses Mendel and Punnett.
The Dihybrid Cross and Independent Assortment
Examines the principle of segregation versus the principle of independent assortment and their effects on genetic data; and the concept of dominance.
