Analysis of a Snork - Monitored Homework - Assign after reviewing the codon chart - Next class, post drawing up on board, discuss what characteristics the DNA coded for. o Do you notice anything difference about each snork? o What happened? o Show a picture of the Snork for the correct DNA sequence o Start a conversion about errors in DNA? Good or bad? o PPT on Mutations How Does DNA Determine the Traits of an Organism? Name: ______________________________________ Introduction: In the simulation, you will examine the DNA sequence of a fictitious organism: the Snork. Snorks were discovered on the planet Haa Hig in a distant solar system. They are a small creature who flies at night. Snorks only have one chromosome with 6 genes on it. Your job is to analyze the genes of the Snork’s DNA and determine what traits the organism has. mRNA sequence UGG UCG UCU UUG GCG CCC UCC UUU AAA CCA AUA AAU UAC GAU CCU Amino Acid # 20 16 2 4 3 5 7 8 9 12 13 1 6 10 11 Amino Acid Sequence 20-11-13 20-12-13 20-21-21 13-14-15 16-2-5 16-4-5 12-7-8 5-7-8 9-8-8 9-4-8 11-3-2 11-3-3 6-6-10 6-6-1 Trait Hairless Hairy Plump (Fat) Skinny 4 legged 2 legged Round Head Block Head Curly Tail Straight Tail Narrow Slanted eyes Wide Big round eyes Wings No Wings Observations and Analysis of Snork DNA – V1 ____________________________________ Name: You are given a chromosome from a Snork with the following sequence. Each gene has only 3 amino acids. Your job is to determine the sequence of amino acids for your specimen. Transcribe the DNA code into a complimentary mRNA sequence in the chart below. Use the table on the previous page to translate each 3 base mRNA code into an Amino Acid number, then into a trait.
