Mississippi Science L.8.2C.1
The Standard
- L.8.2C
- Students will demonstrate an understanding that chromosomes contain many distinct genes and that each gene holds the instructions for the production of a specific protein, which in turn affects the traits of an individual.
Communicate through diagrams that chromosomes contain many distinct genes and that each gene holds the instructions for the production of specific proteins, which in turn affects the traits of the individual (not to include transcription or translation).

What This Standard Means
What Students Need to Do
- Students draw a chromosome with many separate genes. They use labels and arrows to show how a gene gives instructions for a protein that can affect a trait.
What Mastery Looks Like
- A student can label several distinct genes on one chromosome. They can trace one gene to hemoglobin, then show how that protein helps red blood cells carry oxygen.
Common Misconceptions
- Students may draw one gene per chromosome or place genes outside chromosomes. Some treat genes as proteins or draw a gene changing a trait directly, with no protein in between.
How to Assess It
- On an exit ticket, ask students to draw a chromosome with at least four distinct genes. Have them choose one gene and add labeled arrows from it to a protein, then to a trait the protein affects.

Ways to Teach It
Give pairs a paper chromosome strip, five gene stickers, and protein and trait cards to connect with arrows.
Show a diagram with an arrow straight from a gene to hair color; ask students to write what is missing.
Have pairs correct three flawed diagrams, including one with a protein inside a gene and one that skips proteins.
Show a red blood cell photo and a hemoglobin card; have students diagram how a gene affects oxygen carrying.
