DNA, RNA, and Snorks DNA, RNA, and Snorks Name _______________________ Pre-Activity Review Questions: 1) There are 2 parts to the process of protein synthesis. a. During the first part, DNA is “copied” or transcribed into mRNA. What is this process called? ____________________________ b. During the 2nd part, mRNA is translated and used to hook on the correct amino acids. What is this called? _________________ 2) What gets made during the process of protein synthesis?______________________________ 1st LETTER 3rd LETTER Procedure: On the following pages you have been provided with a single strand of DNA for 4 different Snorks. Snorks are alien sea creatures that were discovered on planet Dee Enae in a distance solar system. Snorks only have one chromosome with eight genes. Part 1 - Transcription: “Copy” or transcribe each strand of DNA into mRNA in the table below. Part 2 - Translation: The very first mRNA codon is a start codon. It does not show up in the amino acid sequence. The DNA and mRNA tables have been shaded in to represent each gene. Write the amino acid sequence for each gene in the table labeled Amino Acid Sequences. Use the codon chart below to translate each mRNA codon into the correct amino acid. Then use Trait Descriptions chart to determine each trait from its amino acid sequence.
