Building Knowledge – Part 3



Building Knowledge – Part 1

Genetics 101: Kahn Academy

Step 1. Attempt the knowledge check for this portion of the unit. See bottom portion of this page.

Parts of the DNA Structure and Punnett Squares Knowledge Check – Answer the knowledge check questions. They are located at the end of this document… If you are unable to answer the questions you must complete the knowledge building exercises, step 2. If you are able to answer the questions without any assistance you are ready to move on to the next portion of the unit, Building Knowledge part 2. Submit your work to your instructor via email for feedback.

You are encouraged to complete the knowledge check in a word document. However you are welcome to complete the knowledge check by printing the document and placing it in your biology binder OR complete the following in your biology lab notebook.

Step 2. What is Genetics?

Watch part 1, 2, 3, and part 4



After each view record in your notebook, or in a notes section of a word document, a summary of what you learned. Be sure to record words that are new to you.

- Optional (but excellent study habit): Research the vocabulary definitions and sketch your understanding of that word.

Step 3 What is the structure of DNA?

AND Interactive parts of DNA using the computer…



AND/OR

Hands on contructing DNA paper 2D



AND/OR

Hands on constructing DNA 3D – See Mrs. Kirby Room 1016. It takes about 20 minutes to compose the 3D DNA model.

Step 3 – Details of genetics? Understanding vocabulary: DNA, alleles, homologous, heterozygous, homozygous, genotype, phenotype, and heredity.

Watch this video: You may need to watch this video a couple of times to understand the vocabulary.



AND/OR

Read about it first or second…. This is a great summary of the basics of genetics.



Step 4 – Punnett Square vocabulary and practice completing Punnett squares.

We all learn at different rates and we learn different things from different experiences. Try all or one of the following 3 choices.

Quiz your self. If you can answer these questions you are ready to move on with step 5.

Only complete the …. Monohybric cross

IN ADDITION TO THE ABOVE: Khan Academy Lesson



Step 5 - Showing what you learned

Correct the quiz using a different color (to show your learning) using what you learned the content. Never delete your work. Only use strike through (select the font you would like to change. C lick on format, click on Font, click “strikethrough.”
