What are the three parts of the DNA monomer?
Just like in DNA, RNA is made of monomers called nucleotides. Each nucleotide is made up of three components: a nitrogenous base, a pentose (five-carbon) sugar called ribose, and a phosphate group.
What are the 4 monomers in DNA?
The four nucleotide monomers are distinguished by their bases
- A nucleotide contains adenine.
- T nucleotide contains thymine.
- G nucleotide contains guanine.
- C nucleotide contains cytosine.
What is A monomer of DNA and RNA?
DNA and RNA are polymers (in the case of DNA, often very long polymers), and are made up of monomers known as nucleotides. When these monomers combine, the resulting chain is called a polynucleotide (poly- = “many”).
Is DNA A polymer or monomer?
nucleotides
The proteins we eat, and which we’re made of, are polymers made up of amino acids. And even our DNA is a polymer—it’s made of monomers called nucleotides.
How many monomers make up DNA?
four different monomers
DNA is a polymer made from four different monomers , called nucleotides . These join together in different combinations to make long strands. In a DNA molecule , two strands wrap around each other to form a double helix structure.
How many different DNA monomers are there?
four
DNA is composed of four amino acids: adenine, guanine, thymine and cytosine.
Has 4 kinds included in DNA?
Because there are four naturally occurring nitrogenous bases, there are four different types of DNA nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C).
What’s the difference between RNA and DNA?
There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.
What are the main components of DNA?
In turn, each nucleotide is itself made up of three primary components: a nitrogen-containing region known as a nitrogenous base, a carbon-based sugar molecule called deoxyribose, and a phosphorus-containing region known as a phosphate group attached to the sugar molecule (Figure 1).
What makes up the monomer unit of DNA?
Likewise, what is the monomer unit of DNA and what are its three parts? DNA is a polymer. The monomer units of DNA are nucleotides, and the polymer is known as a “polynucleotide.” Each nucleotide consists of a 5-carbon sugar (deoxyribose), a nitrogen containing base attached to the sugar, and a phosphate group.
How are the nucleotides of DNA a polymer?
DNA is a polymer. The monomer units of DNA are nucleotides, and the polymer is known as a “polynucleotide.” Each nucleotide consists of a 5-carbon sugar (deoxyribose), a nitrogen containing base attached to the sugar, and a phosphate group.
What is the monomer and what are the 3 parts?
What is the monomer of DNA and what are the 3 parts? Nucleic acids are polymers of individual nucleotide monomers. Each nucleotide is composed of three parts: a 5-carbon sugar, a phosphate group, and a nitrogenous base.
