The nucleotides have a similar structure with three 'subunits':
- A phosphate group
- A sugar group : deoxyribose in DNA and ribose in RNA
- A nitrogenous base : adenine, cytosine, guanine, thymine or uracil.

Chemical reaction is a process that changes one set of chemicals into another set of chemicals. In a reactant it holds them together.
What are the three 3 basic subunits of a nucleotide?
Nucleotides are composed of three subunit molecules: a nucleobase, a five-carbon sugar (ribose or deoxyribose), and a phosphate group consisting of one to three phosphates.
How many subunits does a nucleic acid have?
Nucleic acids consist of 3 subunits.
What are the basic subunits of DNA and RNA?
A nucleotide is the basic building block of nucleic acids (RNA and DNA). 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).
What are the basic nucleic acids?
The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the master blueprint for life and constitutes the genetic material in all free-living organisms and most viruses.
What is the basic subunit of protein?
Proteins are made up of hundreds or thousands of smaller units called amino acids, which are attached to one another in long chains. There are 20 different types of amino acids that can be combined to make a protein.
What are the three subunits of DNA?
DNA is made of smaller subunits called nucleotides. Each nucleotide consists of three components: a five-carbon sugar called deoxyribose, a phosphate group, and a nitrogenous base.
What are the basic subunits of DNA and RNA quizlet?
Nucleotides are the subunits of DNA and RNA.
What are nucleic acids made of?
Nucleic acids are made of nitrogen-containing bases, phosphate groups, and sugar molecules. Each type of nucleic acid has a distinctive structure and plays a different role in our cells.
What are the four subunits of DNA?
Each chain is made up of repeating subunits called nucleotides that are held together by chemical bonds. There are four different types of nucleotides in DNA, and they differ from one another by the type of base that is present: adenine (A), thymine (T), guanine (G), and cytosine (C).
What are 4 types of nucleic acids?
The most common types of nucleic acids are: deoxyribonucleic acid (DNA) ribonucleic acid (RNA) messenger RNA (mRNA)
What are the two types of nucleic acid?
The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material in all living organisms, ranging from single-celled bacteria to multicellular mammals. It is in the nucleus of eukaryotes and in the organelles, chloroplasts, and mitochondria.
What are the four nucleotides in the nucleic acid item?
Each nucleotide in DNA contains one of four possible nitrogenous bases: adenine (A), guanine (G) cytosine (C), and thymine (T).
What are the two classes of bases in DNA?
Each nucleotide consists of a sugar (deoxyribose) in the middle of a phosphate group and a nitrogenous base . There are two classes of bases. Two are purines (double-ringed structures) and two are pyrimidines (single-ringed structures). The four bases in DNA's alphabet are: In both DNA and RNA there are four major bases.
How many bases are there in DNA?
The four bases in DNA's alphabet are: In both DNA and RNA there are four major bases. However, RNA has the first three plus uracil. The substitution of uracil for thymine as a base material constitutes the chief chemical difference between RNA and DNA.
What are the subunits of nucleic acids called?
The subunits that make up nucleic acids are called nucleotides.
What is the subunit of a nucleotide?
Additionally, what is the subunit of a nucleotide? Nucleotide. A nucleotide is a subunit of DNA or RNA that consists of a nitrogenous base (A, G, T, or C in DNA; A, G, U, or C in RNA), a phosphate molecule, and a sugar molecule (deoxyribose in DNA, and ribose in RNA).
What are the three things that make up a nucleotide?
A nucleotide consists of three things: A nitrogenous base, which can be either adenine, guanine, cytosine, or thymine (in the case of RNA, thymine is replaced by uracil). A five-carbon sugar, called deoxyribose because it is lacking an oxygen group on one of its carbons. One or more phosphate groups.
A. Experiments that Established DNA as the Genetic Material
The physician Frederick Griffith was interested in developing a vaccine against the bacterium Streptococcus pneumoniae, one of the major causes of pneumonia, ear infections, and meningitis in children.
B. The Structure of DNA and RNA
DNA and RNA molecules have four levels of structural complexity (see figure 5.5 ):
Review Questions
In the Griffith experiment, the ______________ strain of bacteria kills the mouse.
What are the two types of nucleic acids?
There are two types of nucleic acids that are important to living things. DNA (deoxyribonucleic acid) RNA (ribonucleic acid) These molecules are also polymers of smaller units called nucleotides; each nucleotide consist of a sugar (ribose or deoxyribose), a phosphate group, and one of several "bases" that are either purines or pyrimidines.
How many nucleotides are in DNA?
DNA consists of two nucleotide chains that are bonded to together by weak hydrogen bonds between complementary base pairs. The double strands are wrapped to form a double helix.
What are proteins made of?
Proteins are another class of enormously diverse organic molecules that are made from multiple units of simpler molecules arranged in chains. All proteins are made from combinations of the 20 amino acids show below. As shown below, each of these 20 amino acids has a central carbon (the alpha carbon) bonded to an amino group (-NH 2 i.e., nitrogen bonded to two hydrogens) at one end and a carboxyl group ( -COOH) at the other end.
Why are proteins called polypeptides?
Proteins are sometimes referred to as polypeptides because they consist of chains of amino acids linked together with peptide bonds.
What is the secondary structure of a protein?
Secondary Structure of Proteins. The chains of amino acids establish the primary structure of a protein, but interactions (both attractive forces and repulsive forces) among the components of the chain reshape the protein into its filnal three-dimensional structure.
What distinguishes one amino acid from another?
What distinguishes one amino acid from another is the side chain of atoms that is also bonded to the alpha carbon (designated " R-group on the right).
What is the name of the structure that a polypeptide twists into?
Hydrogen bonding can cause portions of the polypeptide chain to form zig-zag sections called " beta sheets " (which are very prominent in the protein fiber in silk, for example), and it can also cause sections of the polypeptide to twist into a cork screw-shaped structure called an " alpha helix .".
