What 3 structures make up a DNA nucleotide?
What 3 structures make up a DNA nucleotide?
DNA and RNA are made up of monomers known as nucleotides. The nucleotides combine with each other to form a polynucleotide, DNA or RNA. Each nucleotide is made up of three components: a nitrogenous base, a pentose (five-carbon) sugar, and a phosphate group (Figure 1).
What are the main components structures in DNA?
DNA has three types of chemical component: phosphate, a sugar called deoxyribose, and four nitrogenous bases—adenine, guanine, cytosine, and thymine. Two of the bases, adenine and guanine, have a double-ring structure characteristic of a type of chemical called a purine.
What are the 4 structures 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).
What are the structural components of nucleotides?
A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base. The bases used in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T). In RNA, the base uracil (U) takes the place of thymine.
What are the three components of a DNA nucleotide quizlet?
Nucleotides each have three parts: phosphate, sugar molecule, and one of four bases. The bases include: A, (adenine), g (guanine), t (thymine), c (cytosine).
What are the components of nucleotides quizlet?
What are the components of a nucleotide? a sugar, a phosphate group and a nitrogenous base.
What are the components of a DNA nucleotide quizlet?
What are the building blocks of nucleotides?
Nucleotides are the building blocks of nucleic acids ; they are composed of three sub unit molecules: a nitrogenous base (also known as nucleobase), a five-carbon sugar (ribose or deoxyribose), and at least one phosphate group.
What are the three parts of a nucleotide?
A nucleotide is made up of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base. The four nitrogenous bases in DNA are adenine , cytosine , guanine , and thymine . RNA contains uracil, instead of thymine.
What are the four types of nucleotides in RNA?
But unlike DNA, RNA uses the nucleotide uracil (abbreviated as U)inplaceofthymine(T). Thus, the four RNA nucleotides are adenine (A), cytosine (C), guanine (G), and uracil (U). Second, the nucleotides in RNA also exhibit complementary base pairing.
How many nucleotides in DNA?
There are four DNA nucleotides, each with one of the four nitrogen bases ( adenine , thymine , cytosine , and guanine ). The first letter of each of these four bases is often used to symbolize the respective nucleotide (A for adenine nucleotide, for example). DNA forms a two-stranded spiral, or double helix.
