In a previous unit you learned about the important functions of proteins. List as many as you can remember. Refer to the Biochemistry unit for help if needed.

Essential question:

How does DNA direct protein synthesis?

Lesson 4.2 Learning Targets

Get a hard copy of this table from your teacher. Below are the learning targets you will master during this lesson.

As a pre-assessment, before the lesson begins, please circle the number that describes your current understanding of the learning target.

Before the formative assessment for this lesson, please draw a triangle around the number that describes your understanding of the learning target.

Before the summative assessment, please draw a square around the number that describes your understanding of the learning target.

Lesson 4.2 vocabulary

Get a hard copy of this table from your teacher. Below are the vocabulary terms you will master during this lesson.

As a pre-assessment, before the lesson begins, please circle the number that describes your current understanding of the term.

You will complete the “Definitions” and “Extra Practice” (shaded gray*) as we progress throughout the unit.

Before each formative assessment, you will reassess your understanding of the terms.  When instructed, please draw a triangle around the number that describes your understanding of the term.

Finally, at the end of the unit (before the summative assessment) you will make a final assessment of your understanding of the terms.  When instructed, please draw a square around the number that describes your understanding of the term.
