About This Chapter
Advances in DNA technology have changed our world. These discoveries have helped find cures for diseases, led to the development of medications and helped us to prevent genetic defects. Genomics and DNA technology are the focus of this chapter. You'll watch videos that cover:
- Comparative genomics
- Genetic modification
- The Human Genome Project
- Restriction enzymes
|Comparative Genomics: Prokaryotes Vs. Eukaryotes||Study repetitive sequences, junk DNA and introns and why they are important.|
|Comparative Genomics: Chromosome Number||Discover the diversity of chromosomes in different species.|
|PCR: The Polymerase Chain Reaction||Learn more about the polymerase chain reaction, including a study of amplification, Taq polymerase and primer.|
|Cloning, Restriction Enzymes, and Plasmids||Explore concepts including cloning, restriction enzymes, plasmids, blunt ends and sticky ends.|
|Microarrays: Analyzing Genes on a Chip||Examine topics that include gene expression analysis and genotyping.|
|Human Genome Project||Analyze what the Human Genome Project was about, what it accomplished and what's new in Next Gen Sequencing Technology.|
|siRNA||Study the inhibition of translation of complementary mRNA.|
|Genetically Modified Organisms: What Are They?||Discover why people create genetically modified crops and livestock and compare these altered organisms to traditional ones.|
|Genetically Modified Food: Golden Rice||Explore the idea of genetically modified rice.|
|Genetically Modified Food: Herbicide Resistant Crops||Examine the concept of herbicide-resistant crops.|
|Genetically Modified Food: Genetically Modified Cows||Learn more about genetically modified cows, including studying vocabulary like mastitis, staphylococcus aureus, staphylococcus simulans, lysostaphin, hypoallergenic milk and beta lactoglobulin.|
1. Comparative Genomics: Prokaryotes vs Eukaryotes
Prokaryotic cells and eukaryotic cells have some obvious differences in size and complexity, but we'll explore additional differences in how their DNA is structured and functions. Test your knowledge with a brief quiz.
2. Comparative Genomics: Homology
Evolutionary heritage links many modern species by way of a common ancestor. Homology examines the structural similarities between species that reveal their ancestry. Here we will examine the concepts of homology, look at examples, and finish with a brief quiz.
3. Comparative Genomics: Chromosome Number
The genetic blueprint of an organism is contained in its chromosomes. Different species have different numbers of chromosomes. In this lesson, we will examine the concept of chromosome numbers as it applies to genomics and follow up with a brief quiz.
