How Does DNA Determine the Traits of an Organism?
In this simulation, you will examine the mRNA sequence of a fictitious organism - the Snork. Snorks were discovered on the planet Dee Enae in a distant solar system. Snorks only have one chromosome with ten genes on it.
Analyze the genes of four Snork DNA samples and determine what traits the organism has. You must show ALL your work!
Then, sketch the organism (Be creative!).
For simplicity, the gene sequences are much smaller than real gene sequences found in living organisms. Each gene has two versions that result in a different trait being expressed in the Snork.
Each of the following mRNA samples was taken from volunteer Snorks. Your job is to analyze each sample and determine the phenotype (how the organism looks) based on the sequence. Remember that AUG is a start codon, and it signifies the beginning of each gene. UAA is a stop codon and signifies the end of a gene. The genes are in order from gene 1 to gene 10 and are separated by a vertical line (|).
