What are the 4 DNA strands?

What are the 4 DNA strands?

The DNA molecule is made up of four nucleobases – adenine, cytosine, guanine and thymine – and can configure itself in a number of ways. It creates a four-stranded structure when four guanine bases form a square – guanine is the only base able to bond with itself.

What does A DNA molecule consists of?

The DNA molecule consists of two strands that wind around one another to form a shape known as a double helix. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases–adenine (A), cytosine (C), guanine (G), and thymine (T).

What are the five components of DNA?

DNA is made up of six smaller molecules — a five carbon sugar called deoxyribose, a phosphate molecule and four different nitrogenous bases (adenine, thymine, cytosine and guanine).

Why is DNA important to life?

DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.

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.
