DNA
Understand the Problem
The question seems to be a simple search term related to DNA, which could encompass a wide range of topics such as its structure, function, or role in genetics.
Answer
DNA is a double-stranded helix with base pairs A-T and G-C.
DNA is a double-stranded helix molecule containing genetic information, held together by hydrogen bonds between nucleotide base pairs: adenine with thymine and guanine with cytosine.
Answer for screen readers
DNA is a double-stranded helix molecule containing genetic information, held together by hydrogen bonds between nucleotide base pairs: adenine with thymine and guanine with cytosine.
More Information
DNA consists of two long strands forming a double helix. These strands are made of nucleotides, which include a phosphate group, a sugar group, and a nitrogen base. The order of these bases (A, T, G, C) forms a genetic code.
Tips
A common mistake is confusing DNA with RNA; RNA is single-stranded and uses uracil instead of thymine.
