20 per nucleotide.
Purines
a DNA nucleotide
Nitrogen bases are like the letters of the alphabet because 1. they sound like A,B,C,D but really are A, T, C, G. 2. they can come in any order.
The three subunits that make up a nucleotide are:Nitrogenous base (adenine, thymine, guanine, cytosine)Sugar (ribose)Phosphate groupNucleotides are organic molecules that serve as the monomers, or subunits, of nucleic acids like DNA and RNA.
1. Duplication - Where a portion of a chromosome is duplicated, resulting in multiple copies of the region. 2. Deletions - When a deletion of a nucleotide (nitrogen bases of a DNA) causes a shift of the mRNA codons. This will cause Alternations of Amino Acids. 3. Insertions - Occurs when an extra nucleotide is added. 4. Inversions - When a portion of a chromosome breaks off and reinserts itself in the same spot but in the reversed position 5. Translocation - When a portion of 2 chromosomes break off and switch locations
they differ about .1% of their bases
the three components that make up a nucleotide are a phosphate,deoxyribose and a nitrogen base
A nucleotide is composed of a nitrogenous base (adenine, guanine, cytosine, thymine, or uracil), a ribose sugar (ribose or deoxyribose), and a number of phosphates (1 to 3).
1. Phosphate 2. Sugar 3. Nitrogenous bases
There are three:1. A phosphate group.2. A 5-carbon sugar compound (deoxyribose).3. A nitrogen base.
Purines
4 nitrogen bases :adanine,cytosine,thymine,guanine
There are four elements, vix. Carbon,(C) , Hydrogen(H), Nitrogen (N) and Oxygren (O). There eight(8) x carbon nine (9) by hydrogen one (1) by nitrogen two (2) by oxygen . Total number of atoms is 8+9+1+2 = 20 The answer!!!!
1 amino acid
a DNA nucleotide
There are no hours in nitrogen.
Nitrogen bases are like the letters of the alphabet because 1. they sound like A,B,C,D but really are A, T, C, G. 2. they can come in any order.
