Essential Questions:
How does genetic information result in protein production?

The Goal:
  • Explain the processes of transcription and translation.
  • Describe the types and roles of RNA molecules in gene expression.

Part 5: Use these instructions and links to answer questions 13-22

1. Study the picture to understand the "big picture" of gene expression.
(Here's what I want you to notice: First, a small part of the DNA is "copied" in the nucleus. The process of TRANSCRIPTION reads part of the DNA (the gene), making a complementary strand of mRNA. Transcribe means "rewrite." Next, the mRNA leaves the nucleus and travels into the cytoplasm where it binds with a ribosome. The ribosome moves along the mRNA during the process of TRANSLATION, where the language of nucleic acid (DNA/RNA) is translated into the language of protein.)

2. Choose to watch either the "lightbulb" icon links to Bozeman DNA/RNA Parts 1 and 2 (Mr. Anderson) OR the three blue "heart" icon links to Amoeba Sisters videos.

3. Answer the questions and submit.
