A. DNA stores and transmits genetic information. Genes are sets of instructions encoded in the structure of DNA.
B. Genetic information is passed from generation to generation by DNA in all organisms and accounts for similarities in related individuals.
C. Manipulation of DNA in organisms has led to commercial production of biological molecules on a large scale and genetically modified organisms.
D. Reproduction is characteristic of living things and is essential for the survival of species.

Gene transcription is controlled by multiple factors. Some proteins bind to DNA sequences and start the process of gene transcription. RNA synthesis can only occur when these activators are bound to specific DNA sequences. This tutorial will help you to understand the process of gene transcription.
Type: Tutorial
You will see how the genetic code, using the DNA alphabet A,T,C, and G, produces codons to specify the 20 known amino acids. Each codon consists of a three letter code producing 64 possible words which specify the amino acids and stop signals.

The lac operon is a set of genes which are responsible for the metabolism of lactose in some bacterial cells. Students will explore the effects of mutation within the lac operon by adding or removing genes from the DNA.
- Predicts the effects on lactose metabolism when the various genes and DNA control elements are mutated (added or removed).
- Predicts the effects on lactose metabolism when the concentration of lactose is changed.
- Explain the roles of Lacl, LacZ, and LacY in lactose regulation.
