That's a tough question, but I might be able to give you an idea of how many there actually are... Human DNA is divided into 23 paired chromosomes, 22 pairs of autosomes and 1 pair of sex chromosomes. There are about 3 Billion nucleotide pairs packed away in there, most of it inactive at any one point in time. It's believed that much of the DNA is inactive, meaning that it is not currently expressed, and therefore not responsible for creating proteins. However, the inactive DNA could be responsible for early fetal development; we aren't entirely sure what all of the DNA does, although all of it has been mapped out... Now back to the initial question. A molecule is defined as 2 or more atoms connected by chemical bonds. Each DNA strand is comprised of two Phosphate Deoxyribose backbones, held together by nucleotides (Adenine, Cytosine, Guanine, and Thymine), bound by Hydrogen bonds. So technically, every DNA segment that's connected is one molecule...therefore, there are 46 molecules of DNA in each human cell. But, if what you were asking how many molecules are assembled for the DNA in each cell, I'd bet 4 per each nucleotide, 1 for each side of the backbone, and 1 for each nucleotide pair. That's about 12 Billion molecules, but they are joined by chemical bonds, and therefore are not individual molecules anymore once assembled.
A single unit of DNA is called a nucleotide.
A nucleotide is made up of a pentose sugar called deoxy ribose, a nitrogenous base and a phosphate group.
Each molecule of deoxyribose has 5 carbon atoms + 10 hydrogen atoms + 4 oxygen atoms
= 19 atoms
There are four kinds of nitrogenous bases in DNA:
Adenine, thymine, guanine, cytosine
Adenine has 8 atoms in it
Guanine has 16 atoms
Thymine has 6 atoms
Cytosine has 7 atoms
Phosphate group has about 4 atoms.
So the total value is about 29-39 atoms.
DNA only has 5 different atoms - carbon, hydrogen, oxygen, nitrogen and phosphorous.
According to one estimation, there are about 204 billion atoms in each DNA .
It depends on the species but humans have 23 pairs or 46 chromosomes (DNA molecules) total.
Trillions of cells in the human body but it may not true because cell can die every time
there is a DNA strand in every cell within your body, i.e., millions
A chromosome is one massive strand of DNA, technically it would be one continuous molecule.
23,299 genes contained in 23 base pairs.
A water molecule is formed when two hydrogen atoms bind covalently to a single oxygen atom.
DNA
No. The sides of the DNA molecule is made of alternating deoxyribose sugar molecules and phosphate groups.
DNA is a very large chemical compound, deoxyribonuclelic acid. DNA makes up every part of human and animal body chemistry.
Nitrogenous bases (ATCG)
Atoms are the basis of physical matter, and elements are made of atoms. DNA is a very complex molecule made of many atoms. It is like the difference between concrete blocks and an apartment building.
It depends on the organism. In human DNA there are approximately 3 billion "rungs."
DNA is a molecule. It is made up of multiple atoms joined together.
the answer is four (4) billion pairs
Each chromosome is originally made of one DNA molecule.

Many molecules such as organic molecules have significantly large amounts of atoms such as sugar/sucrose (C12H22O11). Others have more Many molecules such as organic molecules have significantly large amounts of atoms such as sugar/sucrose (C12H22O11). There other molecules such as DNA and polymers that have no size limit and there is no maximum size of a molecule.
