Which substance is not part of nucleotide?
The three components of a nucleotide are a 5-carbon sugar, a phosphate group, and a nitrogenous base. A nucleotide does not contain phospholipids; those are molecules that make up the cell membrane and nuclear envelope.
What substance is part of a nucleotide?
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).
Which substance is not part of a molecule?
Single atoms of elements are not molecules. A single oxygen, O, is not a molecule. When oxygen bonds to itself (e.g., O2, O3) or to another element (e.g., carbon dioxide or CO2), molecules are formed.
Is nitrogenous base part of a nucleotide?
Nucleotides. Nucleotides include: (1) a nitrogenous base, (2) a five-carbon monosaccharide (aldopentose), and (3) phosphoric acid. Nitrogenous bases. Nucleotide hydrolysis produces two types of substances derived from the heterocyclic rings purine and pyrimidine known as the purine and pyrimidine bases.
What are the four different nucleotides?
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).
Which of the following is not the function of nucleotides?
d) Receptors is the answer.
What 3 components make up a nucleotide?
Nitrogen-Containing Base. The nitrogen-containing base is arguably the most important element in a nucleotide,since the type of base dictates the information that actually makes up the genetic code.
What does a nucleotide not contain?
A nucleotide does NOT contain a a 5-carbon sugar b polymerase c nitrogen base d a phosphate group. A quarry is an area where minerals, rocks, and sand are extracted from the Earth’s surface. The place where the Six Flags amusement park now stands in San Antonio, Texas, used to be a quarry….
Which nucleotide is not found in RNA?
The sugar in the nucleotides that make an RNA molecule is ribose, not deoxyribose as it is in DNA. The thymine nucleotide does not occur in RNA. It is replaced by uracil . When pairing of bases occurs in RNA, uracil (instead of thymine) pairs with adenine .
What elements make up a nucleotide?
Elements of Nucleic Acids . The phosphate groups allow the nucleotides to link together, creating the sugar-phosphate backbone of the nucleic acid while the nitrogenous bases provide the letters of the genetic alphabet. These components of nucleic acids are constructed from five elements: carbon, hydrogen, oxygen, nitrogen, and phosphorous.
