What are the smaller molecule that DNA is made of?
nucleotide bases
DNA is a linear molecule composed of four types of smaller chemical molecules called nucleotide bases: adenine (A), cytosine (C), guanine (G), and thymine (T).
What are DNA molecules called?
nucleotides
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C).
What is the name of the small molecules that together form A long molecule of DNA?
Each DNA strand within the double helix is a long, linear molecule made of smaller units called nucleotides that form a chain.
What are the smaller monomers that DNA is made of called?
The monomers of DNA are called nucleotides. Nucleotides have three components: a base, a sugar (deoxyribose) and a phosphate residue. The four bases are adenine (A), cytosine (C), guanine (G) and thymine (T).
How many strands of DNA make up the DNA molecule?
two strands
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.
What are the 4 molecules 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).
How many molecules are in a strand 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).
What makes up the rungs of DNA?
DNA Replication Combinations of these atoms form the sugar-phosphate backbone of the DNA — the sides of the ladder, in other words. Other combinations of the atoms form the four bases: thymine (T), adenine (A), cytosine (C), and guanine (G). These bases are the rungs of the DNA ladder.

What is the basic structure of DNA?
DNA Structure. DNA ( deoxyribonucleic acid) molecules are nucleic acids, which are the information-carrying molecules of the cell. DNA molecules are polymers and are made up of many smaller molecules, called nucleotides. Each nucleotide contains a phosphate group, a sugar molecule, and a nitrogenous base.
What is the difference between DNA and RNA nucleotides?
The structure of RNA nucleotides are also similar to those of DNA; both contain a phosphate group, a sugar molecule, and a nitrogenous base. However, there are some key differences between DNA and RNA molecules. Whereas DNA contains deoxyribose, RNA contains a different type of sugar molecule, called ribose.
What is an organism’s complete set of DNA called?
An organism’s complete set of nuclear DNA is called its genome. Besides the DNA located in the nucleus, humans and other complex organisms also have a small amount of DNA in cell structures known as mitochondria. Mitochondria generate the energy the cell needs to function properly.
What is the Order of nucleotides in a DNA molecule called?
The order of the nucleotides in a DNA molecule is known as the DNA sequence or genetic code. The genetic code determines which instructions are encoded in the DNA molecule; for example, how to make a certain type of protein.
