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.

∙ 9y agoA 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.
A human DNA molecule consists of about 6 billion atoms. These atoms are arranged in a specific sequence that encodes genetic information.

According to one estimation, there are about 204 billion atoms in each DNA .

The basic structural unit of molecular compounds is the molecule. A molecule is a group of atoms bonded together, representing the smallest unit of a compound that retains its chemical properties. Molecules can be simple, consisting of just two atoms (like oxygen gas, O2), or complex with many atoms bonded together (like DNA).
The sides of the DNA molecule are made up of repeating sugar-phosphate groups, not nitrogen bases. The nitrogen bases are arranged in the middle of the DNA molecule and form the rungs of the double helix structure.
Hydrogen bonds play a crucial role in various biological processes, such as the formation of DNA double helix, protein folding, and water's unique properties. They result from the attraction between a hydrogen atom covalently bonded to an electronegative atom (like oxygen or nitrogen) and another electronegative atom nearby. This weak interaction helps maintain the structure and stability of many biological molecules.
A water molecule is bigger than a carbon atom. A water molecule consists of three atoms (two hydrogen and one oxygen), whereas a carbon atom is a single atom.
DNA is a biotic molecule because it is found in living organisms and is essential for their genetic information and inheritance.
Neil deGrasse Tyson compares the number of atoms in one molecule of DNA to the number of stars in the Milky Way galaxy.
Atoms are the basic building blocks of matter, consisting of protons, neutrons, and electrons. DNA, on the other hand, is a complex molecule that carries genetic information in living organisms. While atoms make up everything in the universe, DNA specifically codes for the instructions needed for an organism to develop, grow, and function.
The phosphate group in a DNA molecule is composed of a phosphorus atom bonded to four oxygen atoms.
The black pentagons in a DNA structure typically represent the phosphorus atoms found in the DNA backbone. These phosphorus atoms help to form the backbone of the DNA molecule, connecting the nucleotide bases and providing structural stability to the molecule.
the answer is four (4) billion pairs
DNA is a molecule. It is made up of multiple atoms joined together.
No, benzene is not a DNA molecule. Benzene is an organic compound consisting of six carbon atoms in a ring with alternating single and double bonds, while DNA is a large molecule comprising nucleotides that contain genetic information. Benzene is not a component of DNA.
HPV (human papillomavirus) has a double-stranded DNA genome, composed of one circular DNA molecule.
Bacterial DNA is single strand. Human DNA in the nucleus is double helix. So, with human DNA, the DNA must first split apart before an RNA molecule can read it.
