Delivered on: 17 OCTOBER 2022
This video delves into the fascinating world of plant genetics, exploring the structure and function of plant genomes and the intricate processes of gene expression. 🌿 We'll uncover the secrets hidden within plant DNA and how it orchestrates the complex symphony of life.
What you'll learn:
Plant Genomes: We'll introduce the concept of the plant genome, its size, and organization, and how it varies across different plant species.
Gene Structure and Function: Explore the structure of genes, the fundamental units of heredity, and how they encode the information for building and maintaining a plant.
DNA Packaging: Understand how DNA is packaged within the nucleus, from the double helix to chromosomes, and the roles of histone proteins and chromatin.
Heterochromatin vs. Euchromatin: Learn about the different types of chromatin and their influence on gene expression.
Chromosome Structure: We'll examine the key features of chromosomes, including centromeres, telomeres, and nucleolar organizer regions.
Transposons: Discover the intriguing world of "jumping genes" and their impact on genome evolution.
DNA Methylation: Explore how DNA methylation can regulate gene expression and affect plant development.
