Leaping Lizards Lesson 1
Lesson 1 of the Leaping Lizards unit introduces students to the basic concepts of genetics. Students will learn about the structure and function of DNA, the different types of genes, and how genes are inherited.
Key Concepts
- The structure and function of DNA
- The different types of genes
- How genes are inherited
DNA Structure and Function
DNA is a molecule that contains the instructions for an organism’s development and characteristics. It is made up of four different types of nucleotides: adenine, thymine, cytosine, and guanine. These nucleotides are arranged in a specific order, which determines the genetic code.
The genetic code is read by cells to produce proteins. Proteins are the building blocks of cells and are responsible for a wide range of functions, including metabolism, growth, and reproduction.
Types of Genes
There are many different types of genes, each of which codes for a specific protein. Some genes are essential for life, while others are not. Some genes are inherited from both parents, while others are inherited from only one parent.
Inheritance
Genes are inherited from parents to offspring through the process of meiosis. Meiosis is a type of cell division that produces gametes, which are sex cells. Gametes contain half the number of chromosomes as regular cells. When two gametes combine during fertilization, they form a zygote, which contains the complete set of chromosomes.
The zygote develops into an embryo, which eventually develops into a fetus. The fetus inherits half of its genes from its mother and half from its father.
