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?
The most common position for esterification of a phosphate group on a pentose nucleotide is the 5' carbon of the sugar. This is because it is the primary site for linking nucleotides in DNA and RNA chains.
Name for DNA subunit?
Nucleotide
Which nucleotide will bind A nucleotide to parental DNA?
A adenine (A) nucleotide will bind to thymine (T) nucleotide in parental DNA through hydrogen bonding.
What is a SNP?
A SNP (Single Nucleotide Polymorphism) is a variation at a single position in a DNA sequence that occurs when a single nucleotide (A, T, C, or G) differs between individuals. SNPs are the most common type of genetic variation in individuals and are used in genetic studies to understand genetic predispositions to diseases and traits.
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.

Which mutation occurs when one nucleotide is replaced with another base?
Substitution

Which nucleotide will bind A nucleotide to parental DNA?
A adenine (A) nucleotide will bind to thymine (T) nucleotide in parental DNA through hydrogen bonding.
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 is of Nucleotides?
Nucleotide is the monomer. Nucleotide is the monomer of Nucleic Acids.
How does the sugar in a DNA nucleotide differ from that in a RNA nucleotide?
The sugar in a DNA nucleotide contains one less oxygen atom.
How does the sugar in a DNA nucleotide differ from of an RNA nucleotide?
