Let’s go through each question one by one, using the word bank provided.

1. The molecule of heredity, contains the “blueprint” for building an organism:
This is talking about the main genetic material that carries instructions for life. That’s
DNA.
✔ Answer:
DNA
---
2. Sugar found in DNA, makes up the sides of the ladder:
DNA has a sugar called
deoxyribose (that’s why it’s called *deoxyribonucleic* acid). It forms part of the backbone (“sides”) of the DNA ladder.
✔ Answer:
deoxyribose
---
3. Sugar alternates with this molecule on the sides of the ladder:
In DNA, the sugar (deoxyribose) alternates with
phosphate groups to form the sides of the double helix ladder.
✔ Answer:
phosphate
---
4. These make up the rungs (center) of the DNA ladder, can be 4 different types:
The rungs are made of nitrogenous
bases: adenine, thymine, cytosine, guanine — so the general term here is
bases.
✔ Answer:
bases
---
5. DNA is made of repeating subunits called:
DNA is built from small units linked together — those are called
nucleotides. Each nucleotide has a sugar, phosphate, and base.
✔ Answer:
nucleotides
---
6. DNA is in the shape of a:
Everyone knows DNA looks like a twisted ladder — that’s called a
double helix.
✔ Answer:
double helix
---
Final Answer:
1. DNA
2. deoxyribose
3. phosphate
4. bases
5. nucleotides
6. double helix
