Question

3.

What can you infer about the structure of DNA using the information in this model? Think
about the Building DNA GIZMO that we did in class. Which statement is TRUE about the
structure of DNA?
This figure shows a section of a double-stranded DNA molecule
The numbers of each nucleotide determine genetic information.
O Paired nucleotides are held together by covalent bonds
ODNA has two strands and each is made up of a phosphate-sugar backbone
Adenine pairs with Cytosine and Guanine pairs with Thymine

Answer 1

Answer: DNA has two strands and each is made up of a phosphate-sugar backbone

Step-by-step explanation:

DNA is double stranded. The backbone of each strand consists of phosphate groups bound to ribose sugars.

Adenine pairs with Thymine A - T

Cytosine pairs with Guanine G - C

The nucleotides in DNA are held together by hydrogen bonds not covalent.
