A nucleotide is composed of:
1.) A nitrogenous base (either a purine such as Adenine or Guanine, or a pyrimidine such as a Thymine or Cytosine; Uracil is the nitrogenous base that replaces Thymine in RNA)
2.) A ribose sugar (5 Carbon ring)
3.) A phosphate group
The nitrogenous base is attached to Carbon 1 on the ribose sugar while the phosphate group is attached to Carbon 5 of the same sugar. (That same phosphate group is attached to Carbon 3 of a neighboring sugar when forming a strand.)

What three common parts of a nucleotide?
Phosphate groups can be esterified at any hydroxyl group on a pentose nucleotide What position is the most common?
5'
Subunit of DNA consisting of a nitrogeneous base a sugar and a phosphate group?
nucleotide = in a nucleic-acid chain, a subunit that consists of a sugar, a phosphate, and a nitrogenous base. The subunit in a nucleic acid chain that consists of a sugar a phosphate and a nitrogenous base is a nucleotide.
What is a U nucleotide?
U is the nucleotide abbreviation of uracil
Which nucleotide will bind A nucleotide to parental DNA?
t
How common are single nucleotide polymorphisms?
One in every 1,000 base pairs of DNA
How are nucleotide sequences used to put organisms in evolutionary order?
When comparing nucleotide sequences in organisms, we find that the organisms that have less differences in their nucleotide sequences are closer related in the evolutionary tree. By this we mean that the common ancestor from which these two organisms evolved is more modern than the ancestor they might share with an organism that shows more difference in the DNA sequencing. Example: the chimps and humans share a common ancestor that is relatively modern because the difference in their nucleotide sequences is just about 1% but the differences between the nucleotide sequence of humans and fish shows lots of differences which shows their common ancestor y much older than the one with chimps.
What is a monomer of nucleic acids?
Nucleotide is the monomer. Nucleotide is the monomer of Nucleic Acids.
What three common parts of a nucleotide?
How would you know if organisms shared a common ancestor?
The closer the DNA pattern (the nucleotide base pairing), the closer the species from a common ancestor.

Subunit of DNA consisting of a nitrogeneous base a sugar and a phosphate group?
nucleotide = in a nucleic-acid chain, a subunit that consists of a sugar, a phosphate, and a nitrogenous base. The subunit in a nucleic acid chain that consists of a sugar a phosphate and a nitrogenous base is a nucleotide.
What nucleotide is present in RNA but not in DNA?
deoxythymidinetriphosphate (dTTP) is the nucleotide in DNA that is not present in RNA. The corresponding base is thymine (T). RNA contains the nucleotide uridinetriphosphate (UTP) instead. In their incorporated forms, the will be in the monophosphate state.Note: Someone previously changed this to read "Deoxythymine is the nucleotide in DNA that is not present in RNA. The corresponding Rna base is Uracil." While they had good intentions, this represents several common errors in molecular Biology. "Deoxythymine" does not exist as a nucleotide (or anything at all for that matter). The nucleoside is called deoxythymidine. If a nucleoside such as deoxythymidine is paired with one or more phosphate groups, it is then a nucleotide.
What does a nucleotide not contain?
A nucleotide does not contain an organic acid.A nucleotide is similar to a nucleoside but does not contain a polymerase.
What is a U nucleotide?
U is the nucleotide abbreviation of uracil
Which nucleotide will bind A nucleotide to parental DNA?
t
What is of Nucleotides?
Nucleotide is the monomer. Nucleotide is the monomer of Nucleic Acids.
