Study Notes
Genetic Processes
- Transformation is the process by which extracellular DNA is taken up by a bacterial cell and integrated into its genome.
Horizontal Gene Transfer
- Conjugation is the transfer of genetic material between bacterial cells through direct contact.
Heredity
- Heredity is the process that involves the transmission of genetic material from parent to offspring.
Genome
- Genome refers to the entire genetic complement (DNA) of an organism.
Bacterial DNA
- Circular bacterial DNA is typically shaped like a circle.
Eukaryotic Genes
- Exons are the coding segments of a eukaryotic gene.
Transcription
- The promoter is the specific region of a gene where RNA polymerase can bind and begin transcription.
Gene Regulation
- The advantage of operons is that they allow multiple genes involved in a single process to be regulated simultaneously, ensuring efficient use of cellular resources.
