2. the ______ is found inside the cell and protects the dna.
3. the ______ are tightly wound strands of dna inside the nucleus.
4. ______ is a molecule that holds the instructions for building all of the proteins in our body.
5. a ______ is one section of dna that has the instructions to make a specific protein.
6. a ______ is built by the cell using the instructions found in a gene.

part 2: multiple choice - circle the correct answer for each question.

1. which list correctly shows how genetic material is organized?

a. gene → chromosome → dna → cell
b. cell → nucleus → chromosome → dna → gene
c. dna → gene → chromosome → cell
d. chromosome → cell → gene → dna
