The DNA’s structure. Structure of DNA
A DNA ________ looks like a twisted ladder. Because of its shape, a DNA molecule is often called a “_______ _____.” A helix is a shape that ______.
*Looks like a twisted ladder
*The sides of the ladder are made of _______________ and _____________>
*The rungs of the ladder are formed by pairs of ______________. Nitrogen bases are molecules that contain the element _________ and other elements.
Within the nucleus of every cell are long ________ of DNA, the ____ that holds all the information needed to ____ and ________ every cell within a living organism.
The bases on one side of the DNA ladder match up in a specific way with the bases on the other side. Adenine (A) - Thymine (T),
Guanine (G) -Cytosine (C)
This pairing pattern is the key to understanding how DNA ____________________ occurs.
Try your own:

DNA replication ensures that each ___________ cell will have all of the _______________ information it needs to carry out its activities.
A DNA molecule “unzips” between its paired ______. New bases pair with the base on each strand. As a result, two __________ DNA molecules form.
Units which, when linked to sugar, make up one side of the DNA ______
New nucleotides move in and go to each side of the ________ ladder. The bases on these _________________ are very particular about what they connect to.
