GIZMO: Building DNA Quiz with complete solution
Look at the DNA molecule shown to the right. What does it look like?
a twisted ladder
Based on this picture, how do you think a DNA molecule makes a copy of itself?
it splits and untwists
What are the two DNA components shown in the Gizmo?
nucleoside and phosphate
How many different nitrogenous bases do you see?
4 (Adenine, Cytosine, Guanine, and Thymine)
What makes up the sides of the DNA molecule?
phosphates and sugar
What makes up the rungs of the DNA molecule?
nitrogenous bases
Adenine joins to
Thymine
Cytosine joins to
Guanine
Thymine joins to
Adenine
Guanine joins to
Cytosine
An eznyme is a protein that facilitates certain cell processes. Click release enzyme to
release DNA helicase. What does this enzyme do to the DNA molecule?
It splits it in half
What are the three parts of a nucleotide?
phosphate, sugar and nitrogenous base
Why is DNA replication such a important process?
Because a cell cannotgrow and reproduce (or divide) unless DNA has been replicated.
chromatin
