What traits are heritable? How different is your DNA from a frog's, a mouse's or even your relative's? Can your genes tell doctors what is the right dose of a medicine for your body? These are the types of questions scientists are answering with genetics and genomics. By studying individual genes as well as genomes, the whole set of DNA belonging to an organism, scientists hope to get a more complete understanding of how our bodies work and develop better disease treatments.
Unsure of what the steps of the scientific method are? Not sure how to apply the scientific method? Watch how we use the scientific method to explore the science of popping boba – fun juice filled balls that pop in your mouth.

There are load of terms to know about DNA, and in this video we explain all the main ones - genes, alleles, homozygous and heterozygous, dominant and recessive, genotype and phenotype. Along the way we'll see how genes and inheritance really works!
The passing down of traits from parent to child is called heredity and the study of how those traits go from generation to generation is called genetics. We start by learning what are DNA and genes and how they make us who we are. Find out more about the science of genetics.
Heredity ['hə-re-də-tē]
The passing of traits to from parents to offspring by the genes of the parents. Who are you? Find out more about heredity on this episode of Science Trek!

This video tutorial is an easy step-by-step guide for using the NCBI BLAST bioinformatics tool for your genomic research. We walk you through how to do a nucleotide or protein BLAST and give you tips for interpreting your BLAST results. We will also show you how to create an evolutionary tree from your BLAST results and demonstrate how to use BLAST for multiple sequence alignment. With the information provided in this tutorial, you should be ready to tackle your own bioinformatics and genomic…
This video tutorial provides a quick overview of the NCBI website. We walk you through how to search for nucleotide and protein sequences using NCBI’s databases and explain what information is provided with each sequence. We also give you tips on how to interpret gene data and guide you through the process of assessing gene variants and mutations using NCBI’s Variation Viewer. With the information provided in this video, you should be well equipped to start your own bioinformatics or genomics…
How do weeds impact crop growth? Why should farmers be concerned about the growth of weeds (unwanted plants) in their crops? This video demonstrates a simulation activity found in the lesson plan, "The Science of a GMO."
