Study Notes
Gene Anatomy
- A gene is the basic unit of heredity, consisting of a sequence of DNA nucleotides on a chromosome that encodes a protein, tRNA, or rRNA molecule.
- Genetic engineering involves the direct manipulation of one or more genes, often by adding a gene from another species to an organism's genome to give it a desired phenotype.
Genetic Engineering
- Genetic engineering is the process of using recombinant DNA technology to alter the genetic makeup of an organism.
- It involves the manipulation of the genetic material of an organism.
- Recombinant DNA is created by splicing together fragments of DNA from two different species, such as a bacterium and a mammal, into a single molecule.
Key Concepts
- Gene direction: refers to the orientation of a gene in an organism's genome.
- Types of genes: various types of genes exist, each with unique functions and characteristics.
- Structure of a gene: includes the sequence of DNA nucleotides on a chromosome that encodes a protein, tRNA, or rRNA molecule.
- Identifying a gene: involves recognizing and isolating a specific gene from an organism's genome.
