What are the components of DNA?

The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all people.

How much DNA is in a cell?

A human cell contains about 6 pg of DNA.

What are 5 differences between DNA RNA?

Summary of Differences Between DNA and RNA DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. DNA is a double-stranded molecule, while RNA is a single-stranded molecule. DNA is stable under alkaline conditions, while RNA is not stable. DNA and RNA perform different functions in humans.

What are the 4 main elements that make up DNA?

Learn About Nucleic Acids and Their Function Nucleic Acid Monomers. Nucleotides are composed of a nitrogenous base, a five-carbon sugar, and a phosphate group. DNA Structure. DNA is composed of a phosphate-deoxyribose sugar backbone and the four nitrogenous bases: adenine (A), guanine (G), cytosine (C), and thymine (T). RNA Structure. DNA and RNA Composition. More Macromolecules.

What are the 4 main parts of DNA?

DNA contains four basic building blocks or ‘bases’: adenine (A), cytosine (C), guanine (G) and thymine (T). The order, or sequence, of these bases form the instructions in the genome. DNA is a two-stranded molecule. DNA has a unique ‘double helix’ shape, like a twisted ladder.

What 4 bases make up DNA?

The four bases found in DNA are adenine (abbreviated A), cytosine (C), guanine (G) and thymine (T). These four bases are attached to the sugar/phosphate to form the complete nucleotide, as shown for adenosine monophosphate.

What are the four base pairs in DNA?

The four bases of DNA are Guanine, Cytosine, Adenine and Thymine. In the double helix of DNA, Guanine always binds with Cytosine and Adenine always binds with Thymine.
