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 3.5. 1).
What are the subunits monomers of RNA?
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. Each nitrogenous base in a nucleotide is attached to a sugar molecule, which is attached to one or more phosphate groups.
What are the subunits of DNA and RNA quizlet?
Nucleotides are the subunits of DNA and RNA.
What are the subunits monomers of DNA?
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).Which subunits form a nucleotide of DNA?
Nucleotides are the subunits of DNA. The four nucleotides are adenine, cytosine, guanine and thymine. Each of the four bases has three components, a phosphate group, a deoxyribose sugar and a nitrogen-containing base.
Which of the following structure is the subunit to make RNA?
Nucleic acids (DNA, RNA) are large polymers, made out of monomer building blocks called nucleotides. The nucleotides have a similar structure with three ‘subunits’: A phosphate group. A sugar group : deoxyribose in DNA and ribose in RNA.
What are the three subunits of a DNA 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. The four nucleobases in DNA are guanine, adenine, cytosine and thymine; in RNA, uracil is used in place of thymine.
What polymer makes up DNA?
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.Which nucleotide subunits are not found in RNA?
RNA nucleotides contain the nitrogenous bases adenine, cytosine, and guanine. However, they do not contain thymine, which is instead replaced by uracil, symbolized by a “U.” RNA exists as a single-stranded molecule rather than a double-stranded helix.
What subunits make up DNA quizlet?One of the four DNA chemical subunits that make up the genetic alphabet: Adenine, Thymine, Cytosine, and Guanine. These subunits join together in specific ways to create genetic words and sentences in the DNA.
Article first time published onWhat are the bases of DNA and RNA quizlet?
The nitrogenous bases in DNA are adenine (A), guanine (G), thymine (T), and cytosine (C). The nitrogenous bases in RNA are the same, with one exception: adenine (A), guanine (G), uracil (U), and cytosine (C).
What are the three subunits of a nucleotide quizlet?
- five carbon sugar aka deoxyribose.
- phosphate group.
- nitrogen base (adenine, thymine, cytosine, guanine)
What are RNA nucleotides?
Nucleotide RNA and DNA are polymers made of long chains 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. … In RNA, the base uracil (U) takes the place of thymine.
How many subunits does DNA have?
A DNA molecule consists of two long polynucleotide chains composed of four types of nucleotide subunits. Each of these chains is known as a DNA chain, or a DNA strand. Hydrogen bonds between the base portions of the nucleotides hold the two chains together (Figure 4-3).
What four bases make up DNA?
There are four nucleotides, or bases, in DNA: adenine (A), cytosine (C), guanine (G), and thymine (T). These bases form specific pairs (A with T, and G with C).
What are the subunits that make up carbohydrates?
Carbohydrates are used by the body for energy and structural support in cell walls of plants and exoskeletons of insects and crustaceans. They are made of smaller subunits called monosaccharides. Monosaccharides have carbon, hydrogen, and oxygen in a 1:2:1 ratio.
What subunits make up proteins?
Proteins are made of subunits called amino acids and are used to build cells and do much of the work inside organisms. They also act as enzymes helping to control metabolic reactions in organisms. Amino acids contain two functional groups, the carboxyl group (-COOH) and the amino group (-NH2).
How many nucleotides make up a codon?
Codon is the name we give a stretch of the three nucleotides, you know, one of A, C, G, or T, three of which in a row, that code for a specific amino acid, and so the genetic code is made up of units called codons where you have three nucleotides that code for a specific amino acid next to another three nucleotides, …
Which of the following includes all of the pyrimidines found in RNA and DNA?
While thymine, cytosine, and uracil are all pyrimidines, only thymine and cytosine are found in DNA. Uracil replaces thymine in RNA. Adenine is a purine, and is found in both DNA and RNA. 4.
What makes up the DNA backbone?
Phosphate Backbone A phosphate backbone is the portion of the DNA double helix that provides structural support to the molecule. … 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), or thymine (T).
Which compound is not part of a DNA nucleotide?
Uracil is not found in DNA. It is only found in RNA, where it replaces thymine (which is not found in RNA). Uracil binds with adenine in RNA.
How do monomers of DNA differ from those of RNA?
DNA is a double-stranded molecule, while RNA is a single-stranded molecule. … DNA and RNA base pairing is slightly different since DNA uses the bases adenine, thymine, cytosine, and guanine; RNA uses adenine, uracil, cytosine, and guanine. Uracil differs from thymine in that it lacks a methyl group on its ring.
What monomers make up nucleotides?
- A five-carbon sugar.
- A base that has nitrogen (N) atoms.
- An ion of phosphoric acid known as phosphate (PO43-)
How are nucleotides in a DNA polymer connected?
The nucleotide monomers in a DNA polymer are connected by strong electromagnetic attractions called phosphodiester bonds. Phosphodiester bonds are part of a larger class of electromagnetic attractions between atoms that chemists refer to as covalent bonds.

What are nucleotide bases quizlet?
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).
Which of the 4 bases of DNA corresponds to Au in RNA?
RNA uses the base uracil (U) rather than thymine (T) The only difference between the two molecules is the presence or absence of the CH3 group.
Which nucleotide base is found only in DNA quizlet?
a) thymine and cytosine are only found in DNA, whereas adenine and guanine are only found in RNA.
