In DNA, the four Nitrogenous bases are A= Adenine, T= Thymine, C= Cytosine, and G= Guanine. A pairs with T and G pairs with C through strong bonds called "Hydrogen Bond." A-T base-pairs are held together by 2 Hydrogen bonds, whereas, G-T base-pairs are held together by 3 Hydrogen bonds. If you are familiar with their structures, you can easily see where the "active" part of the molecules are located, aka where the Hydrogen bonds are formed.
WARNING: As these particular bonds are the most desirable and MOST COMMON, it is POSSIBLE for a scenario to occur, where for example, an A (Adenine) binds to G (Guanine) base. Such a case, would therefore lead to what is known as a "mutation," during the Replication Process of DNA. There are numerous types of causes (i.e., natural vs. "unnatural"), types (i.e., deletion, insertion, etc), and results (i.e., gene expression) of mutations.

What is complementary sequence?
When DNA and/or RNA are in the double helix configuration each helix is the complementary sequence of the other.
Describe the 3 dimensional structure of DNA?
DNA has two polynucleotide molecules that spiral around an imaginary axis to form a double helix. only certain bases in the double helix are compatible with each other. Adenine pairs with thymine and guanine pairs with cytosine.
Each half of the DNA strand. Why is DNA called the double helix?
DNA is called a double-helix because it consists of two strands that spiral around each other. A spiral shape is also called a helix, and there're two of them, so it's a double-helix.
Why did Watson and Crick refer to the DNA molecule as a double helix?
Because that is the shape of the molecule: two helices wrapped around each other. Note: due to defective x-ray crystallography photos early in their work, Watson and Crick mistakenly originally reached the tentative conclusion that the DNA molecule was a triple helix with the bases pointing outward, instead of its actual shape of a double helix with the bases pointing inward and linked in pairs by hydrogen bonds.
What holds to strands of DNA molecule to each other?
The two strands of DNA are held together by hydrogen bonds between the nitrogen base pairs.
What is the name of the twisted ladder shape of a DNA molecule?
nitrogenous bases linked together

Which best describe the structure of DNA?
(Apex) Sugar-phosphate backbones with bases on the inside.

How do the bases help form the helix shape?
The bases in DNA (adenine, thymine, cytosine, and guanine) form hydrogen bonds with each other. Adenine pairs with thymine, and cytosine pairs with guanine. This pairing creates a double helix structure, with the bases forming the "rungs" of the ladder and the sugar-phosphate backbone forming the "rails". This hydrogen bonding between the bases is responsible for the stability and shape of the DNA helix.
What holds to strands of DNA molecule to each other?
The two strands of DNA are held together by hydrogen bonds between the nitrogen base pairs.
How do nitrogen bases along a gene serve as a genetic code?
Yes, it is found in pairs Adenine with Thymine and Guanine with Cytosine...they are directly across from each other (horizontally) on the DNA line ( also known as a double helix) there can be many of these on one double helix
DNA is a macromolecule that is shaped like a double?
Each strand of DNA in the double helix can serve as a pattern for duplicating the sequence of bases. This is critical when cells divide because each new cell needs to have an exact copy of the DNA present in the old cell.
