Meiosis, DNA Replication, & Gene Expression

You’ll now continue connecting previous knowledge with understanding how genes go from a sequence of nucleotides to ultimately being physically expressed in an organism.

BY THE END OF THIS WEEK, you should be able to:

  • use all appropriate terminology found on your week 20 terms to know,

  • describe the process of meiosis while contrasting its phases with that of mitosis,

  • review the steps of how genes move from DNA to RNA to proteins, and discuss the central dogma of molecular biology. Essentially, can you describe the process of transcription and translation?

Week 20 - Biology

Your Week Ahead

Day 1: DNA Structure & Replication

  1. I’ll be with students on a field trip today, please review the following videos in the content video section of the website.

    1. Start with Videos 5 and 6 in the genetics section: DNA Structure and DNA replication. Take Notes on these videos! I’ll check next class.

    2. Next, watch videos 1 and 2: reviewing mitosis and diving into meiosis. We’ll begin next class with a lab walking through meiosis so watching this video will be helpful.

  2. After class, read pages 344-353 in your textbook and prepare for your quiz this Day 3 with creating Punnett Squares.

Day 2: Meiosis

  1. We’ll use the day to walk through a meiosis lab to ensure that we understand the important steps of this process.

  2. AFTER CLASS, read pages 362-371 in your textbook and study for your quiz. If you’d like additional review, watch video 4 in the genetics section on how to complete Punnett Squares.

Day 3: Quiz and the Central Dogma of Molecular Biology

  1. You’ll start class with a quiz by completing Punnett squares then analyzing them.

  2. After this, you’ll jump into a discussion on the central dogma of molecular biology (Transcription and Translation).

  3. After class, read pages 372-383 in your textbook.
