Document Summary
Ib biology 3. 1 - genes - interactive lecture. Genetics and its basics the ib biology curriculum emphasizes genetics, which is the study of genes and heredity. Having a good grasp of the basics of genetics can help you understand this field better and form a strong foundation for comprehension. One of the fundamental concepts in genetics is that of genes. A gene is a segment of dna that is coded to create a protein, which in turn determines a particular trait. Dna sections that do not contain genes are commonly referred to as junk dna. Gene location is also important, but there"s more to it than just identifying the spot. Every gene has a unique code that produces a different version of the same trait. For instance, the location of the gene that causes sickle cell anemia is 11q1. 4q2. 1 on chromosome 11"s long arm (q). Sickle cell anemia is a blood disorder that is caused by a specific dna mutation.
