Each nucleotide is a polymer made up of three parts:
- A five-carbon sugar (2'-deoxyribose in DNA or ribose in RNA)
- A phosphate molecule
- A nitrogenous (nitrogen-containing) base
What are the three main components of a nucleotide?
The three components of nucleotide are:
- Sugar Base: Deoxyribose in case of DNA and Ribose in case of RNA
- Phosphate group
- Nitrogen base: Adenine, Guanine, Cytosine, Thymine. In RNA, Thymine is replaced by Uracil.
What three things that make up nucleotides?
Nucleotides each have three parts: phosphate, sugar molecule, and one of four bases. The bases include: A, (adenine), g (guanine), t (thymine), c (cytosine). The phosphate and sugar molecule bonds form the backbone or hand rail of the DNA (staircase), but the genetic key is in the steps (of the stairs): the bases.
How many parts does a nucleotide have?
Each nucleotide is a polymer made up of three parts: The five bases are adenine, guanine, cytosine, thymine, and uracil, which have the symbols A, G, C, T, and U, respectively. The name of the base is generally used as the name of the nucleotide, although this is technically incorrect.
What are not components of a nucleotide?
Nucleotide Structure
- Nitrogenous base. The nitrogenous base is the central information carrying part of the nucleotide structure. ...
- Sugar. The second portion of the nucleotide is the sugar. ...
- Phosphate Group. The last part of nucleotide structure, the phosphate group, is probably familiar from another important molecule ATP.
What are the common parts of a nucleotide answer?
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. A nucleotide within a chain makes up the genetic material of all known living things.
What are 3 common parts of a nucleotide?
Each nucleotide, in turn, is made up of a nitrogenous base, a pentose sugar, and a phosphate.
What are the common types of nucleotide?
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 are the common parts of the nucleotide 3 answers?
The building blocks of DNA are nucleotides, which are made up of three parts: a deoxyribose (5-carbon sugar), a phosphate group, and a nitrogenous base (Figure 9.3).
What are the 3 parts of a nucleotide quizlet?
nucleotide --> composed of three parts: nitrogenous base, five-carbon sugar (pentose), and phosphate group.
What is nucleotide made up of?
A molecule consisting of a nitrogen-containing base (adenine, guanine, thymine, or cytosine in DNA; adenine, guanine, uracil, or cytosine in RNA), a phosphate group, and a sugar (deoxyribose in DNA; ribose in RNA).
What two parts do all nucleotides have in common?
All nucleotides have two parts that are the same: the deoxyribose sugar and phosphate. The third part, nitrogen base, is different.
What do the four types of nucleotides have in common?
The four types of nucleotides contain four types of nitrogenous bases. Adenine, guanine, thymine and cytosine are nitrogenous bases present in DNA and uracil instead of thymine in RNA.
What are the 4 nucleotides?
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 3 parts of a nucleotide How are they attached to one another?
How Are the Parts of a Nucleotide Connected or Attached? The base is attached to the primary or first carbon. The number 5 carbon of the sugar is bonded to the phosphate group. A free nucleotide may have one, two, or three phosphate groups attached as a chain to the 5-carbon of the sugar.
What are the three parts of a DNA nucleotide and how are they connected to each other?
What are the three parts of a DNA nucleotide, and how are they connected to each other? The three parts are a deoxyribose sugar, a phos- phate group, and a nitrogenous base. The phosphate group and the base are connected to different parts of the sugar.
What are the 5 types of nucleotides?
Names of Nucleotides The five bases are adenine, guanine, cytosine, thymine, and uracil, which have the symbols A, G, C, T, and U, respectively. The name of the base is generally used as the name of the nucleotide, although this is technically incorrect.
What are the 5 nucleotides?
The five bases that are found in nucleotides are often represented by their initial letter: adenine, A; guanine, G; cytosine, C; thymine, T; and uracil, U. Note that A, G, C and T occur in DNA; A, G, C and U occur in RNA.
What are six major nucleotides?
Nucleic acids are broadly divided into two major types; Ribonucleic acid (RNA) which is single stranded containing Adenine (A), Uracil (U), Cytosine (C) and Guanine (G) ribonucleotides and deoxyribonucleic acid which is double stranded containing Adenine, Thymine (T), Cytosine and Guanine deoxyribonucleotides.
What are 3 nucleic acids examples?
The most common types of nucleic acids are:deoxyribonucleic acid (DNA)ribonucleic acid (RNA)messenger RNA (mRNA)transfer RNA (tRNA)ribosomal RNA (rRNA)
Answer
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 three parts of a nucleotide?
They also have functions related to cell signaling, metabolism, and enzyme reactions. 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. A nucleotide within a chain makes up the genetic material of all known living things. They also serve a number of function outside of genetic information storage, as messengers and energy moving molecules.
Which molecule contains nucleotides?
Another molecule that contains a nucleotide is cyclic AMP (cAMP), a messenger molecule that is important in many processes including the regulation of metabolism and transporting chemical signals to cells.
What are the four nitrogenous bases in DNA?
The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine. RNA contains uracil, instead of thymine. A nucleotide within a chain makes up the genetic material of all known living things. They also serve a number of function outside of genetic information storage, as messengers and energy moving molecules.
What is the central information carrying part of the nucleotide structure?
Nitrogenous base. The nitrogenous base is the central information carrying part of the nucleotide structure. These molecules, which have different exposed functional groups, have differing abilities to interact with each other.
How many phosphate groups are in ATP?
ATP contains three phosphate groups, which can store a lot of energy in their bonds. Unlike ATP, the bonds formed within a nucleotide are known as phosphodiester bonds, because they happen between the phosphate group and the sugar molecule.
What is the idea arrangement of a nucleotide?
As in the image, the idea arrangement is the maximum amount of hydrogen bonds between nucleotides involved. Because of the structure of the nucleotide, only a certain nucleotide can interact with other. The image above shows thymine bonding to adenine, and guanine bonding to cytosine. This is the proper and typical arrangement.
Why are there uneven spots in DNA?
Uneven spots are created when hydrogen bonding does not occur between the opposing nucleotide molecules.
