Reflection: Connection to Prior Knowledge The Central Dogma (#5 of 6): Translation - Section 4: Closure: What did we learn? Where do we go from here?


From Day #1 to Day #5, there has been a carefully scripted "staircase of complexity" regarding the ever challenging topic of molecular genetics.

First, students were introduced to the basic structure of nucleotides wherein they compared and contrasted DNA and RNA.

Next, students were introduced to the purpose and process of DNA replication and the base pairing rules that permit this to happen.

Then, the DNA-RNA interactions that occur during transcription were added as the next layer of detail. The key aspect with this step is remembering the two sets of base pairing rules (A-T, G-C with DNA-DNA and A-U, G-C with DNA-RNA).

Lastly, three types RNA in two regions of the cell plus the introduction of amino acids forming proteins were added as the "pièce de résistance"!

The Central Dogma (#5 of 6): Translation

Unit 3: 4) DNA & RNA ("Instructions for Life")
Lesson 8 of 10

Objective: Systems of specialized cells within organisms help them perform the essential functions of life. (HS-LS1-1) All cells contain genetic information in the form of DNA molecules. Genes are regions in the DNA that contain the instructions that code for the formation of proteins, which carry out most of the work of cells. (HS-LS1-1 & HS-LS3-1)

Big Idea: The structure of DNA is a double helix. Its shape explains how hereditary information is stored and passed along to offspring.
