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.
