Name:___________________________________________ Introduction: In this simulation, you will examine the DNA sequence of a fictitious organism - the Snork.

DNA, RNA, and Snorks

Snorks were discovered on the planet Dee Enae in a distant solar system. Snorks only have one chromosome with eight genes on it. Your job is to analyze the genes of its DNA and determine what traits the organism has and then sketch the organism (You can be creative here). For simplicity, the gene sequences are much smaller than -real- gene sequences found in living organisms. Each of the following DNA samples was taken from volunteer snorks.

1.3 Structure & function of proteins

Scientists find a crucial new role for DNA we once considered junk. How a firefly's tail makes light. One reason that fireflies glow is to attract a mate.

How a firefly's tail makes light

Males and females of the same species will flash signals back and forth as a way of communicating. Each firefly species has its own particular pattern. For example, the fireflies of one species will fly around in the night sky and dive steeply just as the flash begins and turn upward to make a distinctive J-shaped pattern of light. Female fireflies hang out on a tree branch or in the grass while the males fly around showing off their best flashes. When a female recognizes the flash from a male of the same species, she will answer with her best flash. Another reason that fireflies glow is to avoid predators. One species of firefly that can't make its own lucibufagens acquires it by eating others that can. Anatomy of a Gene. Transcribe and Translate a Gene. How do Cells Read Genes? It's not a mistake when we say that ATG is a start codon.

How do Cells Read Genes?

Scientists generally consider AUG to be a start codon in mRNA sequence and ATG to be a start codon in a DNA sequence. But... If AUG on an mRNA molecule means "start,"and mRNA is copied from a DNA template,and the DNA template is complementary to the mRNA copy,then why isn't a DNA start codon TAC? The key thing to remember is that DNA is double stranded. Here's a DNA sequence, with the start codon in red: We've shown the sequence of just one of the DNA strands. While our shorthand version shows just the top strand, it's actually the bottom strand that RNA polymerase reads to build an mRNA molecule. But that's not quite right. The scientific standard is to write a nucleotide sequence from 5' to 3'.

It would be more accurate to say that the DNA sequence of the "start codon" on the bottom strand is CAT. For the sake of ease and clarity, scientists tend to ignore the bottom strand (they call it the "non-coding" or "antisense" strand).
